It was late at night when I finished installing these so the look wasn't the best. To see them clearer check out this video here: th-cam.com/video/-MDRneQl1hM/w-d-xo.htmlsi=are9GYB4nIuBXLHj 👍👍 If you want a set for YOUR C7 Corvette get them here: bit.ly/43zwJQJ
Sick ZR1!!!!! Those diffuser fins are a nice touch!!!!!
Looks awesome. My 2017 Grand Sport had them on already when I bought it. I have ordered lifting pucks and the protective socket from ACS, because of your Z06 Videos
Thank you! 😁
Thanks! That's awesome to hear! I'm glad I could help! 😁
HorsePower Obsessed How much horsepower but I have now
That little trick of un-clipping the rear fascia on both sides is a life saver. Thank You!!
You're welcome!
@@HorsePowerObsessed Unclipping the rear fascia AND taking out the two bolts above the exhaust are great tips that nobody else is showing in their videos, you are the man! Great job, thanks!
OH BLESS YOU FOR MAKING THIS VIDEO! I’m installing these Friday and all I’ve heard was how hard it was. Now with these cool tips I’m already feeling a lot better! Thanks Justin!
You're welcome, Steve! Definitely not hard with this new method. 👍👍
Hi Justin, another great video! Nice to see your installation video featured on the ACS website! Your install video was pre-rear facia extension install. I have already installed the rear facia extensions. Any recommendations given my situation? Thank you!
Thank you! You should be able to take the screws out without any issue still. The rivets will keep the facia extensions in place while you move the rear facia around.
I'm not first, I'm not last. but when it comes to HorsePowerObsessed, I click fast.
🤣🤣 I appreciate that!
@@HorsePowerObsessed today u were FIrst!
@@chrisiden1 👍👍
Likewise. And as a result I open my purse nearly as often. I find that odd since I'm usually the one who's blamed for spending other peoples money. ;)
The car looks great with the fins installed J. You made it look simple. That new method is great. Would have saved a pound of flesh installing mine several months ago had I known. Lol Thx man...good job. 👍😉
Lol thanks! It definitely helped that's for sure!
Hi Justin, just installed the rear diffusers on my 2017 Z06 - your video was very helpful and saved me a lot of time!!
Glad it helped! 👍👍
Thanks Justin, You've given me the confidence to tackle this. I've had my ACS rear diffuser fins for over 6 months.
You're quite welcome! You can definitely do it. 👍
Lol. I was the same. Took me like 3-4 months to get them on. Although I did have help. Justin's vid wasn't out yet. Lol
@@FrontSeatDriver I wish I would have known about this way earlier because when I installed these on my Z06 it was nowhere near this easy!
I have been thinking about the rear diffusers for my vette. TY for the tips on installing. Can't beat ACS for quality. I have a number of their products on my car and have zero complaints.
Exactly my experience. I love their products. The diffuser fins really finish the rear end of the car. I HIGHLY recommend them.
You're really messing up my singularity of thought by resurrecting my bi-polarity Justin. I was all set to go for a C8 and now you AND ACS makes me want a ZR1. Now I've got to go back on my meds. Oh the humanity. 😂 Save the Wave.
Save the money and get a C7, Peter! The C8 is great, but it won't be "better" than the ZR1 until at least the Z06 iteration and at that point it's going to be well over 100k. Plus, ACS has all kinds of stuff out already for the C7! 😁
Roger that.
Justin thank you I installed my diffuser today your video help a lot

You're very welcome! Thanks for the picture! Looks great!
Hey bro, I’m 5’4” 125Ibs and this was also a pain to install, I did it to my 2nd C7 and it didn’t hurt this time. The first time my right arm was so messed up, it looked like I did my own tattoo with three needles and wrecked it. So if you mess things up, then we ALL of us will do likewise. So, keep up the great work for us, so we never mess up. With love ,no homo, Nelson.
Excellent Video!! You make it look so easy installing the read dif fins. The ZR-1 looks so 🔥 with the new fins!
Thank you! It's amazing how much better the rear end looks with these installed!
Great video of the setup Justin. Have to install them on my Z06 this winter. Thanks for the tips. The C7 back bumper without them does look a bit incomplete. I hope the new C8 Z06 have some sort of a diffuser right from the factory. Guess time will tell.
Thanks. I'm hoping the C8 Z06 has one as well!
Great video bro. This method sure makes this a lot easier. Also, really cool that Sam Fisher is watching over the ZR1 😃👌
Thank you! You're the first one to say anything about that poster! 🤣
@@HorsePowerObsessed You are most welcome.
@@DigimortalFM81 👍👍
Looks awesome! I’m tempted to add them to the GS. Nervous about drilling into the rear!😫
You definitely should. I'll give you a hand next time we're together! 👍👍
Sounds good man. 👍 Wonder if it would be any easier up on the lift in my garage.
@@Team512 everything is easier with a lift! 😁👍
Very helpful instructions to my C7 project next week. Thank you
You're very welcome!
Thanks again Justin. Your video made this task much easier to accomplish.
Awesome! Did you get them installed?
Just finished installing the last one.I Just have to button things up. Thanks again for your help.
You're quite welcome. They definitely help the look of the rear end!
I love the upgrades we do to our cars but I just wish there was someone at chevy that had some pride in themselves to finish the car before putting it up for sale.
ACS make great products! No doubt. Love all my stuff.
Definitely agree!
The diffuser fins make the zr1 look even more aggressive from the back awesome video 👍
Thanks, man! It definitely helps finish off the rear end.
Great detailed informative video! We appreciate and need videos like this.
Thank you!
I'm a new subscriber and really enjoy your videos. They're incredibly informative and helpful. I'm adding diffuser fins to my 2014 Z51 soon and this is probably the most helpful installation video I've seen. I'm curious if you considered 14-19 ACS Rear Diffuser Fins (Triple - Carbon Flash)
from Zip Corvettes before going with the traditional two fins on each side. They are a bit pricier (about $120) and I'm thinking three on each side may be a bit much, but I'm still undecided. Do you or others have an opinion? Thanks again and keep the videos coming. And it goes without saying, your car is a monster.
Thank you! I appreciate the kind words. I'm more than happy to help! I did see those diffuser fins and I think three on each side is a little bit too much. 2 on each side looks very stock so it blends in very nicely.
Have them on mine 19 gs makes a huge difference to rear end a must thx justin. Great video
Thank you! It literally changes the look of the rear end. 👍
100 percent looks amazing
Definitely! 😁
Great Video. About the ACS template you used. Was there two templates, one for each side, or did you just flip the template over to do the passenger side?
2. One for each side.
@@HorsePowerObsessed Thank You. I ordered mine. I'm waiting for it to arrive from Canada, then I'll watch your video again and do mine. Keep posting the great videos. I follow most of your stuff.
Thank you so much for your great video. It was very helpful for mounting the fins on my C7 Z06.
But the work was still extremely tedious, because the space is really too small :-)...!
Generally you maintain a super channel, thank you.
Best regards from Switzerland
Thank you! I'm glad I could help out!
I ordered these and haven't received them yet, but now I'm rethinking it. These thick fins are very different than what is on my 458. I now think they look janky and the thickness probably increases air drag.
All going great but the passenger side is fully retracted and I can’t get it loose to finish the install. Ideas
If all the bolts are out you have to pull it towards you while pushing the actual bumper forward towards the front of the car to free the rear facia enough to get your hand in there.
Just about to tackle this job. Thx for the tips !
You're very welcome! It's a lot, but at the end, it looks amazing.
Wow!! That would have made it SOOOOOO much easier! Best install video for this product yet!
Thanks, Jason! It definitely did cut down the install time and the install swear words! 🤣🤣
@@HorsePowerObsessed lol. I bet!! 😜
@@FrontSeatDriver 🤣🤣🤣
Justin, which company sells a diffuser that has this same look as all one piece? I don’t want to drill into my bumper. Looking for a good quality one that has as much of an OEM look as possible.
Only one I know of is APR and it's carbon fiber.
@@HorsePowerObsessed thank you brotha, I appreciate the information
@drakeb.5270 you’re quite welcome!
Justin, one more question on this brother. Which diffusers fins are the best to buy in terms of quality, fitment, etc. the ones from ACS OR the ones from EOS?
If you can please explain the “why” behind your answer in good detail, it would really help me make my decision on which vendor to buy from.
I appreciate you very much.
@horsepowerobsessed
Hello do you still have the paper templates can’t see to find them,if you still have them I can buy them from you!!
Yes I do.
@@HorsePowerObsessedawesome are you willing to sell them to me? I’m in New York!!
got any ideas to make the C8 Exhaust look better???
I think Corsa or Borla might. 👍👍
@@HorsePowerObsessed yes i think so!
@@chrisiden1 I'm anxious to see what they do with it!
Hey man you’re pretty badass and chill love watching the vids
man I was cringing and grinding my teeth seeing the drilling part seeing it move up and down thought it was going to fall
not sure if you remember me but like I said on your video of cost of the ownership of a c7 zo6 I’m finally taking out my Corvette on October been having so much anxiety due to the excitement
Thanks, man! I definitely remember you! The drilling was definitely scary at first. 🤣
HorsePower Obsessed lol yes I bet man great video once again
@@Emilianoo8 thank you! 😁
After the diffuser is on are there any gaps around the ACS product?
There can be, but there is a fair amount of adjustability. After you get them snug you can move them around to eliminate any gaps then tighten it up.
Full carbon fiber ones on aliexpress as well as gold Corvette emblems that would be great with you car. I also have seen entire carbon interiors as well. Check it out on both Alibaba and Aliexpress. Looks pretty good.
Will do!
But those don’t have a template
Looks great I’ll be definitely adding these to my Z soon
I highly recommend them! 👍👍
Awesome how to video! I wonder if that extra bit about loosening the bumper by the vents would work on my Stingray? Also do the vents come in torch red? 👍
It should work for you as well... And FANTASTIC idea about those vents! 👍👍
Justin I need a template can you help me?
Unfortunately, no. The template is on some seriously large paper. I still have mine but in order to copy it it has to be on a gigantic piece of paper.
I’m on the exact opposite boat, I bought a C7Z with the fins and I want to remove them lol
About time you catch up to me installing all the ACS stuff...lol
lol there's more coming soon! 😁
Did you end up with any gaps between the fins and the bumper? ie:see any daylight?
No. You have a good bit of adjustability so they are pretty easy to move around to make sure there isn't any gaps.
Been going back and forth, these or the on piece unit (1 per side). How are they holding up?
Perfect. Definitely an awesome addition. 👍
I love this car.
Me too! 😍
I changed the oil last week, no problem* But drilling holes in it would be like performing brain surgery on myself. For the same reason I have yet to yet to get the ACS front mud guards. And since I live in a desert it's not like there's a lot of sand and rocks here. ;)
*ETA: "Race Ramps" make doing so a lot easier. Have you ever seen or used them?
Yes. I have the 67" race ramps for oil changes, etc. LOVE THEM!
Add some thin red stripes on the fins
I thought about that!
I got it on mine if yould like to see it.
Sure! Send me some pictures!
Dont even know how to do that on here, but here is my email, hrstickers@yahoo.com
Hey man, another great video. These pieces look amazing but do they offer any aero upgrade at all or is it purely for appearance? Thanks!!
It's look and function! At high speed they are functional.
You've got big NADS my friend lol!!! Not a shot in hell i drill any holes in my car. I would puke if something went wrong lol... I was sweating bullets putting on my rock guards and side markers and i didn't drill anything lol. Great video Justin keep them coming!!
Lol thanks! I felt a certain way about it that's for sure!
I picked up my rock guards from ACS and they were great to work with. I went with the Oracle side markers because i got the color match markers (Arctic White).
Nice! Definitely good add-ons!
Love your channel bro! Thanks for the tip, looks pretty easy to install. ordering mine soon. P.s where did you get the smoked license plate cover and corvette plate holder? Pls msg me onwhere to order.
Thank you! The smoke cover is from amazon: amzn.to/32q6UCM and the plate frame is from ebay: ebay.to/2No0Jeb
Nice video work up!
Thank you!
is there by any chance a small gap on the upper tip of the diffuser fins? I installed them and have very small gaps
No. If there's gaps you have room for adjustment with the holes drilled. Loosen up the bolts and move the diffuser around until it sits flush.
@@HorsePowerObsessed okay, I'll try, any particular order work best?
Not really. Just loosen all 3 and get them where you're happy with it and then tighten them back up.
Cool man! Good job! Love it!
Thanks, man! 👍
This was a great video... just wished you would have showed a more... um... clearer and direct view point of the finished product.
That night was late when I finished installing them. I have a bunch of videos on here that show the car afterwards but if you want a good look check out this video here to see them during the day: th-cam.com/video/-MDRneQl1hM/w-d-xo.htmlsi=are9GYB4nIuBXLHj
really nice job when i get my stuff i'll just drop by so YOU can do the install😄 is this strictly cosmetic it does look cool but does it actually do something
I'd be glad to help you with the install! They are functional at high speed! 👍👍
Wow, that came out amazing!
Thank you! 😎👍
great vid. but you should have went carbon fiber and replaced the whole rear bumper. apr makes a stage 1 and a new stage 2. i like the stage 1 better.
Thanks. I looked into the carbon fiber diffuser pieces and I couldn't find any that matched the stock center-lined carbon fiber look. With the spoiler right there it would look weird if it didn't match correctly.
@@HorsePowerObsessed apr's does
It is center-lined?
@@HorsePowerObsessed www.westcoastcorvette.com/p-13014-corvette-aero-rear-diffuser-carbon-fiber-apr-performance-c7-stingray-z06-grand-sport.aspx i have it on my 16 z07 and it fits like a glove and is a work of art.
It does look good but it's not center-lined like the carbon fiber is on the ZR1. Basically, the weave all meets in the center of the piece.
Acs best
Agreed. They make some awesome quality parts.
Looks great, but if I may ask, how do you guys on youtube afford 110k vettes?? I work in IT and could never afford a car that nice. Not ragging, askin'. 😎👍
I worked in IT before I went full time on TH-cam. I always budget my money well and that allows me to afford most of the toys I want.
@@HorsePowerObsessed that is awesome....i just have shitty luck I guess....
New subscriber 💯
Awesome! Thanks for the support, man!
👍👍👍
👍
You were like 5 bolts away from just taking the whole thing off lol
Yup but those rear deflectors really make it a lot more difficult so this is the easiest way.
If Batman weren’t gay, that would be his car! LoL 😂
🤣🤣
For almost $500 the cost of the diffusers fins. I don't think so that's ridiculous.
Quality is never cheap.
They would look better if not so thick...
They do have great, non Chinese parts. Don’t put junk on your car
Agreed!
Why dont you jack the car up. You made this 10 times harder then is necessary.
Sure didn't. Jacking the car up doesn't help at all with this.
HorsePower Obsessed I know you didnt jack the car i watched the video. I have owned a faberication company for 25 yrs
I have awards for full metal restorations. And have been a corvette owner for 25 yrs. that said jacking the car up and not crawling on the car gives you a room to line things up and use tools properly.
I had the installed on my z06 and that was jacked up. No easier or harder. Sorry, height doesn't help here.
That rear wing takes away from the car.
I disagree.
Great video. But, it's an actual fact that you say actual and actually in actually every actual sentence....... Don't get me started on basic and basically....
🤣🤣🤣 thanks for pointing it out! I'll work on it!
