They can build you any suspension you want including their full blown race suspension and prices are very reasonable. The only downside: it probably doesnt make sense to ship your car to Germany to be put on their suspension dyno. I would contact them in case I wanted to step up from the 1LE suspension.

KW are shit in my experience. But to each their own. Couldn’t give me a set.

FYI on the GT4.R stuff:

The front Ohlins damper assemblies are ~$3,800 each.
The rear Ohlins damper assemblies are ~$2,000 each.

The front springs are Hyperco 375lb/in (8") or 550lb/in (7") or 800lb/in (7")
The rear springs are Hyperco 650lb/in (7") or 850lb/in (7")

Front top mounts are ~$630 each
Front spherical slide/plate assembles are ~$390 each.
Rear top mounts are ~$1,080 each.

As soon as I get done with work on the 20th, I will pull out my Quick Jack and put her up in the air and start checking for anything loose, you really can't see much with it on the ground and with all the panels in the way, I did put the stock wheels back on so when I take her to work tomorrow I will know for sure, has anyone tried to adjust the front springs, I haven't read on here if anyone has and if made any difference.

Many of the fastest drivers and teams in Europe and especially at the Nurburgring use them.

What are the spring rates of the ZL1 1LE and the "normal" ZL1?

Maybe I'm lucky to have good tracks around here, but I have yet to experience the car being over-damped on the track. Sonoma/Laguna both have a fairly good surface, though. I'm at probably 4k track miles and (minus one warranty replacement) they are still going strong for me.

I have 11k on mine.

no issues to date.

I had both front shocks replaced under warranty on the ZLE. I had the left front passenger "boink" or "boing". I had enough leak out of the brass fitting to get all over my inner brake caliper to where braking had gotten worse. (I wasn't aware I needed to check on this brass fitting)

Chevy took 4+ months to replace mine. I have 4100 miles on the car and 3k of that is on track.

I am going to DSC Sport with Tractive RTx. They have a custom wiring harness to turn the ZLE into adaptive suspension with the DSC Controller well known to the ZL1 (mag ride) and Corvette Community.

AFAIK, they did run Penske dampers in their TA4 and T2 car.

I do not know for sure. But based off of the various literature on the ZL1 1LE and the components, my guess is: 570-600lb/in front and 540-570lb/in rear.

Again, just my best guess. I'm actually really surprised no one has had the ZL1 1LE springs tested and documented at this point.

I know a guy that had FEA front / rear springs checked. He asked not to publish them. I don't remember the exact #'s off hand, but your front # is high by a decent amount, your rear is WAY low. I'll poke him to see if he has changed his mind.

Good to know.... the GT4.R "Lite" spring package is supposed to be 375/650 and the medium 550/650. I double-checked my notes on Camaro suspension and I definitely fudged something for the assumption on ZL1 1LE front springs: my assumption should be more like 350-400lb/in.

For some reason, the number of "700" stands out to me from reading something about the ZL1 1LE rear springs, but I could never find out where that was mentioned.

[ddipaola]

Sorry to bring this thread back from the dead. Did anyone ever publish the OEM Frt/Rr spring rates for the 1LE's?

[Woody6244]

I read that the fronts are 450 rear 900.
