I can provide part numbers for all of the ZL1 parts except the mag ride shocks. Don't have those, too expensive to retrofit anyway.

92245257 is the old V6 front coil spring, 92195466 is the rear.
20953579 are front SS coil springs, 22737722 are the current V6 front coil springs.
I got all of my part numbers from my dealer. Gmpartsdirect.coms catalog is not maintaned by them, its not up to date or correct in some cases.

I had mine checked when I did my wheels the dealership told me to bring it back they will check it no charge for me. I do not expect anything to change it still drives strait as an arrow so far. I take it in Wednesday so they can have a look on the digital alignment rack.

Looks very nice man

Car looks good, just wondering how much you have into making it look like a ZL1?

I lowered mine 1.25" with Pfadt springs and I had a 4 wheel alignment done two days later and everyhing that could be adjusted was still in spec. The only thing out was the caster was just outside of spec but there is no adjustment from the factory for it. if i understood the guy right it has something to do with the wheel not being centered in the wheel well but its so minor no one would ever know it.

Honestly not much at all

-ZL1 bumper conversion $1500
-(Sold my SS bumper for $500)
-ZL1 Spoiler $400
-(Sold Stock Spoiler $100)
-ZL1 wheels $0.00
-ZL1 Springs $0.00

Total investment $1300 add the ZL1 hood and I am at approx $2200 for everything painted and installed.

For my RS, it's 4 fingers in the rear and about 3.5 fingers (or 4 really tight fingers) in the front. I saw a ZL1 at my local dealership and measured 3 fingers front and rear.

They call them fingers but I never see them fing.

I'm in Maryland, which dealership had the ZL1. I have search dealer inventory several time and unable to find one within 400 miles. You know if it was an automatic? color? year 2013?

Pohanka Chevrolet. Manual, black/black with exposed CF weave, 2013. I believe they were selling it above MSRP, not sure.
