Can't help you there. I'm the C7 Grand Sport owner/driver. I am 100% OEM stock. The C8 was lightly modded, and I have no control over that.

@@PeterReingold would u ever do any mods?

@@thewanderer5124 Hi, nope, the C7 GS is awesome stock. Plus it's my street car.

Thanks, Todd, for the compliment. I think I just know this particular track a little better than the other driver. The C7GS does all the work, it's fantastic on track.

Hey Tony. I'm pretty spoiled because we have Spring Mountain, LVMS, & SpeedVegas here, all in southern Nevada. So I don't really go to any other tracks. I'm thinking in a few years about some road trips to Streets of Willow and perhaps Laguna Seca. Also, I don't 'race'. Mine is a street car that just does fun track days. I do go head-to-head with my friends, and we track our lap times, and they are usually faster than me! But we have a great time.

@@PeterReingold Ive never raced any of those tracks before, maybe i can come out to an event out there sometime and join you. Its not to bad of a drive from San Diego, and im always up for a new track. Like your videos by the way, orange looks very good on the grand sport.

@@103familyracing Thanks, Tony. Your yellow is great-looking also. LVMS is about 2 miles - SpeedVentures goes there about once a year and I join them. SpeedVegas is about 1 mile (but very $$ for their track days, and I think they stopped doing them). Spring Mountain is huge, with many configurations - the Porsche Club Las Vegas runs there 4 times per year, that's when I usually go. They typically run a 3 or 3.5 mile configuration there. You can sign up for e-mail notifications on the PCA-LVR website, and also on MotorsportReg. We usually see a few Grand Sports at Spring Mountain, would love to have you join us.

I do LVMS about once every two years, when SpeedVentures has a track day, or CamaroCon, or LSFest. Fun little track, and so close. My friend's ZL1 1LE is no joke, it is a monster on track. He's in another of my videos at SpeedVegas. With Cup2s, he always pulls away from me!

This vehicle is 8-speed auto. The auto will usually be faster, but the manual is probably a little more fun.

Especially if you have good knees, lol

Thank you! The car is awesome.

100% stock, yes.

For me, no. I think the power is adequate and the handling and braking more than make up for it. That being said, who doesn't always want 100 more HP? However, I don't know how the mods in your list will hold up to full-on track days. While staying 100% stock the LT1 is pretty solid.

Thank you! This car is amazing on track.

I will try those on my next track day. This track day was different, I had crap tires and there was crap on the surface in some corners. The car went into limp mode and hunted for gears in some turns. Never happened before. Normally I really like the Auto shift's logic, but I will try the paddles next time.

@uwegt3 - not sure why you're having these issues. I see many Grand Sports at the track with me, all stock, no one has temperature issues. You may be right, maybe we are all driving too slowly. But I've had four great track days each with four full sessions (30 minutes), with warm outside temps (Las Vegas). No temperature issues. My car is 100% stock, on the OEM run-flat MPSS (NOT cup 2s). And my times are within 1-3 seconds as friends of mine on R-compound tires in Corvettes, ZL1 1LEs, M4s, etc. So I don't think I'm necessarily slow. But this is a street car, and this is HPDE, not racing. My last outing I set the oil temp gauge and watched it for you (and your friend, @997GT3R). Outside temps 90F, my oil temps got as high as 230F-250F. Here's that video - th-cam.com/video/dNl_cWFIoGs/w-d-xo.html Grand Sport has coolers for: engine oil, transaxle, diff, trans, F/R brakes, everything. Too bad you had a bad experience.

I drive a GS at the limit at the track all day and frankly right on past many porches - no cooling problems what so ever. Only way I see you having temp spikes like that is if you have a bad thermostat. It’s a a 35 dollar part and takes about 30min to change. I hope you tried that before you sold the car....

@@thundrune1554 Agreed, this is what I've been trying to explain to these two guys. I was at the track yesterday, 90 degrees all day, ran all day, no cooling issues. There were at least six other Grand Sports doing just fine, all day. I just posted the video, title "Corvette chasing Porsche on track...can I catch him?".

@@PeterReingold hahahaha - you certainly can unless it’s one of those new gt3 cars - cause damn they fast on track.... But a small amount of motor work (heads cam Katech has a nice package) will get you 560hp/500ftlbs at the crank. On a tight track where lateral grip and torque out of corner apex matters the GS is verrryyyyy formidable 😎😎😎

@@PeterReingold and... the gt4 he’s talking about.... yeah fun and beautiful car but no way that hangs with a properly set up GS at the ring.

I did not monitor oil temps. But water temps around 190, all day. These Grand Sports have coolers for everything, so temps are not an issue.

@@PeterReingold Nice if you have no problems. A friend of mine dropped his 2019 Final Edition because at 5° outside temperature the car had more than 140° oil temperature in the shortest possible time on track. And the problem with the Corvette is that the oil is measured at the coolest point in the engine. 😖🤦🏻‍♂️ I like the C7 very much and I actually wanted to buy one. But now I'm not sure if the car doesn't work on the racetrack...😞 Here in Germany the car is still quite expansive and for such a price tag everything must work fine.

@@997GT3R That issue with your friend seems unusual. The LT1 has a dry sump oil system (side-oiler) in the Grand Sport. Plus an oil cooler. Your friend may be using the wrong oil, or sadly may have a bigger engine issue. Check around TH-cam and the Forums, you'll see the Grand Sport stays cool and solid all day long at the track. See my other track videos, plus I have another track day this Saturday, and I'll post up a video of that, too. Good luck!

@@PeterReingold would be great if you can make a video of a long turn run (20 min) with a view of the oil temp :)

@@997GT3R Let me see what I can do, this Saturday.

Thanks, Tom. Both are great. I agree with you that the grip and braking are a little better on the C7GS than the C8Stingray. But the C8 is definitely faster in a straight line. Love my GS on track.

C8 is modded as well to be fair tho

Thanks Jeff.

I used Sport Mode, because I like knowing I have the safety nets. The car is 50/50 weight distribution, so the handling is very neutral. There can be some understeer at the limit, usually after several laps and the front tires start to slip. And if you jump on the power too early, there may be some skip-out oversteer. But very manageable. Lower tire pressures to 25-26 PSI cold, it helps a lot.

Hi Jason. I have had another track day with it after this one (search, "Corvette Grand Sport with Camaro ZL1 1LE open track day at Speed Vegas "). And another scheduled for March & April, too. It is so much fun on the track. Great grip and brakes. Mine is completely stock, I simply upgraded brake fluid. With all of the ducts, and vents, and coolers, the car can run all day, no problem.

Thanks, I do love the overall look and stance of my red Mustang. My guess is that a good set of coil-overs is the superior set-up to what I have.

You may require an adjustable Panhard Bar (PHB) in the rear. If your PHB is centered properly, the fit is perfect 19x11 305/35. When the picture was taken, I had just installed the wheels, and I needed to fine-tune the PHB shortly after the video. I don't think a solid-axle rear end allows for any camber adjustment.

Thanks!

Yes, one Sunday each month. They are trying it out. So far, so good. Check their website speedvegas.com/trackday/

@@PeterReingold Thank you!

@@CamaroSS1 Are you local LV?

@@PeterReingold No.

My Eibachs are not adjustable, and the ride is harsh. If you are not going to track your car, don't get too aggressive shocks/struts. Many folks get Koni and like them. Glad I could help you.

Hello Jose. My car is lowered 1.5" in front, 2" in rear. But...I have -1.5 of camber in the front, so it helps tuck the top of the tire inside the fender. With no spacers, I think 285 is the widest you can go in front, using a 10" wheel. With a spacer, perhaps 305 with an 11" wheel, but that I'm not sure. Be sure to buy wheels with the correct offset and backspacing. The Nittos I have (NT555G2) are great on the street, but weak on track. If you will not track the car, the Nittos are a great value.

Hey T-Rex. The wheels hold up great. I have no chipping, and I actually track these wheels, too. They look brand new, over two years in. I'm not sure what size tire you should get, but if you call LMR and speak to their wheel/tire dept. they can help you, they are excellent staff there.

Peter Reingold I contacted LMR yesterday regarding the tire size. Since the 4 wheels are 20x10’s, they recommended 275’s all the way around to prevent rubbing. I know that you are running 285’s in the front. Do you have a problem with rubbing? To give you an idea of my suspension, I have NOT lowered my car, so I’m still on factory springs. I may lower the car in the future. I know that you are sitting on 19” wheels. I’m not sure if yours is lowered but i want to make sure that there would be no rubbing if I put 285’s in the front. Thank you for your response bro. Much appreciated.

@@traybrook Hey T-Rex. It's not apples-to-apples. My car is lowered 1.5" in front, but I'm on 19s. But...I have -1.5 of camber, so it helps tuck the top of the tire inside the fender. You are not lowered, and going with 20s. So I would go with what LMR recommends, just to be safe.

Peter Reingold thank you sir. That info really helps. Good luck on the channel. Hoping to see more of your videos. 👍

Hello, not exactly. At first I tried camber bolts, but it would not allow enough adjustment. So I had to get adjustable caster/camber plates. I went with J&M, they work great. =1.5 degree of front camber, perfect.

Hi Jacob. No, not really. Just a little bit deeper and louder across the entire rev range. You'll hear the difference. But I don't get the 'pops and gargles' you mention. An off-road x-pipe may give you that.

@@PeterReingold good info. One more question: what exactly did you purchase to REPLACE the resonators, and where did you purchase from?

@@smedlz See my 'part 1' (th-cam.com/video/uMsTaizTklo/w-d-xo.html). 3" straight pipe from same exhaust shop that did the cuts/install for me. Use stainless steel if available. I live in Las Vegas, so aluminized steel is cheaper and will work just fine.

No spacers required - this is the maximum you can go without adding spacers or changing studs, Front 19x10 with 285/35 19; Rear 19x11 with 305/35 19. You will need smaller spline lug nuts because the OEM lug nuts are too fat, but SVE / LMR includes new ones. I don't know how 19x10 look on the rear, these are 19x11.

@@PeterReingold How much are you lowered? I want to do 1" front 1.5" rear.

Lowered about 1.5" front, 2" rear.@@xXBurntBaconXx

I have track videos - here's one with these wheels/tires. th-cam.com/video/rEwR3O6VLV4/w-d-xo.html

Thank you! I think so, too.

Yes, thanks. This was back in 2013 (five years ago), I was still at the beginning stages of road course experience.

Peter Reingold Na man it’s not ur fault. Everyone does it. It’s just on a 5.0 it can really get wild if u don’t stay on the gas. The live axle needs special treatment. But it’s a really fun road coarse car but nobody knows this. They all quick to drag race and stuff

None. Keep in mind that these do not extend past the outer lip of the fenders.

Hi, nope, not an issue.

Hey Tony. I'm lowered about 1.5 inches front, 2.0 inches rear.

@@PeterReingold what springs?

Eibach Sports@@Tony-rs1cv

If your PHB is centered properly, the fit is perfect 19x11 305/35. When the picture was taken, I had just installed the wheels, and I needed to fine-tune the PHB shortly after the video. Perfect fit now.

Wheel Specs: Front - Size: 19x10, Backspace: 7", Offset: +40mm, Weight: 24lbs. Rear - Size: 19x11, Backspace: 8", Offset: +50mm, Weight: 25lbs. No rubbing in the front. The rear needed a little bit of fine-tune adjusting of the PHB to get them centered perfectly. Lowered approximately 2" overall, Eibach Pros.

My previous set-up was 19x9 255/40 front, 19x10 285/35 rear. Believe it or not, I find the ride to actually be a little better on the street with the newer, larger (wider), SVEs that I have now. And much better on the track (road course). I prefer the look and feel of the staggered set-up, so 285 front with 305 rear is great for me now.

Peter Reingold I’m currently on a 255/40/19 squared setup. I hoping there won’t be too much difference between the 40 and 35 sidewall. Still want the wife to be comfortable. I’m pretty sure the ride quality was rougher with my last mustang setup that had 255/35/20 because of the Sr springs I was running. Currently running bmr’s Perfomance spring which doesn’t have such a high spring rate like the Sr lowering springs did. Also I’m running Sr Perfomance shocks and struts this time and last time I was on stock.

Your 35 sidewall on a 20" rim (on your last setup) will ride rough. These 19s ride fine, IMO. But there are other videos on TH-cam with these wheels, ask those folks to get some more opinions to help you with your decision.

Peter Reingold finally got my sve r350 wheels from lmr, you can see them on my profile. What tire pressure are you running for everyday driving with the 285’s in front and 305’s in back? Mine came with 32psi and I left them at that psi since the recommended psi for the stock wheels is 32psi.

Those look great! I run 35psi on the street. 25-27psi (cold) at the track. Maybe my 35psi is too high...?

It’s not trying to make a gt500. It’s the axle backs for the gt500 from ford racing designed to fit the GT. I have them as well and think they make it sound great for the money.

GT500 exhaust is a smidge louder than stock 5.0. Resonator delete makes it a smidge louder than that, with a barely deeper tone. He isn't trying to make it a gt500. Just a bit better sound. Go away mullethead. Stop being jealous that Mustangs still sound like muscle cars, and don't sound like tractors like your camaro/challenger.

Blah Blah - not sure why you think that. It's for better sound, period. Nothing else, perhaps a few extra HP, as well, more exhaust gas-flow. Not trying to make my car anything more than what it is, a 2011 GT.

No rubbing at all. Front turns lock-to-lock, no problem. For the rears, since my car is lowered, I had to fine-tune the Panhard bar a little after install. But the rear does not rub either, now. SVE got the back-spacing and offsets correct with these wheels.

Peter Reingold sweet! thanks for the info....I just saw SVE released the 350R wheels and definitely going to hit those up!

I saw those Rs...they look great, too. I love that we can get a nice wide footprint now for our S197 Mustangs. No spacers needed. Looks bad-a$$. And the cornering grip is very good.

I do NOT think 305s would work in front. Maybe with a specially offset 18" wheel they might. 315s would work in the rear, on 19" x 11"...however 305 is the ideal fit for an 11" wheel.

Hey Humbler, sorry so late. I think 305s in front require a spacer. LMR reports that you can't go wider than 305 in the rear of S197s. Maybe 315 will fit, but might rub a little when the road dips hard.

Eibach Pro Plus (springs, dampers, sway bars), BMR adjustable PHB, J&M c/c plates.

Is that 1” drop in front and 1.5” in back?

It's more like 1.5" front, 2.5" rear (I switched to Eibach Sports for the rears to even out the stance).

Kawaii Kiwi nope it’s glen Taylor

ArmaniGamingYT - Lamping is WAY more strict.
