Added the lowering collars (properly) on my '22 in the fall of 2022...started having issues with the front lift in 2023 and took it to the dealer. No warranty coverage for the car and now have to spend $1K to fix issue. I know of 2 other people with the same issue. Unfortunately, PP stated that it was a faulty install...I have no doubt I did it right!
I bought the lowering collars and I’m having trouble finding a shop to install them. Did you have to replace your front lift assembly? I’m not sure if I want to even install them now, let alone find someone willing to do it.
You guys have the best install videos. Makes me want to buy all my parts that I want from y’all when I’m able to and do all the work my self. Keep up the great job on all install videos.
After lowing the car only on a front collars and rear adjustments, do I need an alignment with a .75" lowered ht.? Also, how much negative cambr would this lowering cause? If so, would this mimic the track alignment without the toe adjustment?
I want to do this to mine, have you heard of any issues or concerns? i hear there is a bulletin out for dealers to look for these. However, i cant really see what issue these would cause.
Only issues we hear about are from improper installs or raising the car while it's on an angle. Any modification to any system will void that parts warranty. We believe GM made the bulletin after noticing many aftermarket solutions for lowering the front lift.
Miguel, you would need to lower the rear threaded collars to the max amount which is approximately 0.7" to match our Front Lift Lowering Collars. We will have a video uploaded today on how to adjust the rear threaded collars using our Paragon C8 Corvette Factory Z51 Coilover Wrench Set.
"Other" kits don't need to either, but they didn't dig into it enough to figure that out. GM uses the exact same bump stop on Z51 cars that do not have front lift as Z51 cars with front lift. So GM out of the factory is assuming those with Z51 cars that do not have front lift when they lower their car the allowed .75 inch on the factory coilovers they need bump stops that will work that way out of the gate for the car. So it's already done correctly from the factory. No need to cut the stops, just for collars. :)
You do not need to cut them just for lowering collars. All Z51 cars use the same bump stops whether they have front lift or not. So those Z51 cars that don't have front lift can lower their cars from the factory .75 inch also and not need to cut bump stops. Same applies for front lift cars since they use the same bump stop. Lowering .75 inch does not require the cutting.
When you watch your video you can see a piece of the cut bump stop. On the counter. Cicio performance says to cut it, your video looks like it is cut yet you say don’t cut it? Please confirm

This is fantastic fellas! Love the video!
What wheels are on the car at the end of the video?
TE037s, 1 of 1 set. We decided not to do a production run on them. Throw us an offer and maybe we'd sell them
Is this with the lowering springs too?
Nope just Front lift lowering and rear coilover lowering

I'm no expert and would need to rent a few of the tools. How much time does it typically take for a novice?
Hey Darren! We would estimate the time to complete the installation is near two hours, but that could vary from person to person.

How much needs to be lowered in the rear to match the front rings. I couldn't find the video...installing in the next days...Thanks

@@ParagonPerformance thanks!
@@miguelalcrudo8810 Video is live on how to use the Paragon Wrenches :)
@paragonperformance if you lower with the collar, shims and springs what’s the total drop 1.5 inches ??
1-3/8” but once it settles it will be about 1.5”
No Mag Ride! What if we don't have mag ride, are these instructions the same? Just without any wires to disconnect?
Yup! Steps are the same
Damm good video boss ! how much is that kit ?
Starts at $99.00 right now.
Other kits cut the rubber bump stop in half. How come your kit doesn't require that?
"Other" kits don't need to either, but they didn't dig into it enough to figure that out. GM uses the exact same bump stop on Z51 cars that do not have front lift as Z51 cars with front lift.

Why don’t you show cutting the bump stop?
You do not need to cut bump stops just for the lowering collars.
Do you keep the stock clearance from the lift system or is that also reduced with an inch?
The front lift still functions as normal. You're just lowering the car a inch in the front.
Did you do any modification to the bump stops?
No, you don't have to for lowering collars.
Do you have to bleed the brakes after collar install?
See 8:27
what size spring compressor do you recommend?
Anything that can fit. You can rent one from your local automotive supplier :)
How come some people cut the bump stops and you guys don’t?

@@c8garage You don't need to cut the bump stops for just the collars.
Can you make one for less? like 0.50 inch?
We do have a shim available that changes our collar from a 3/4" drop to a 3/8" drop. Just choose Add 3/8" Shim! There's no additional charge :)
Well I'm gonna have to skip this mod lol
Why so?!
New Bulletin out in June
No issued worldwide are now seeing enough cars come in with issues that this now voids parts warranty
