The two photos of the springs out of the car (V6 on the right, ZL1 on the left) so you can see the difference.

I used to be able to fit 4 fingers in the wheel well from the top of the tire to the top of the fender, now it's hard to fit 2 fingers in.

Looks so much better now
Any updates now that you've had a few months to drive it?

Have you timed the bushes?

When you lowered your car the alignment changed. It should be aligned at the new ride height after the bushes are timed.

No issues I have been riding on them since August no issues on my daily driver. I took the car in to be alligned it was spot on so no adjustments needed.

Timed mine on the new car but didnt on the old car, same springs. Only difference was the shocks and no difference whether timed bushes or not.I hear they" reset" in about 5 miles anyway.

All the suspension rubber bushings all the movable parts in the suspension mount with. When you lower, or raise a car they are said to twist or in a way preload if not lossened to be allowed to rotate to their new correct position.If the bolts are loosened so they can rotate to the new ride height position, then retighten the bolts, they will be in the correct spot, last longer as no preload is on them and they wont shear or wear badly, and the ride is better by a little bit.

Bump for a pretty cool mod. After reading this thread back in December. I found a set of ZL1 springs for $185 shipped and had them installed around the first week in February. LOVE THEM! Professionaly installed ,bushings timed ,and realinged. The car corners like it's on rails. Very firm,very little roll. The only thing different I have found is my car only dropped 20mm or 3/4 of an inch. Which I like, but want to inform others thinking that because the springs are just over an inch shorter, the car would drop that much. I'm no expert, and my mechanics agrees that the ZL1 springs are stiffer than the ls springs. Like I said ,Great Thread/Mod.

So I've been looking at springs today.

Always felt like the ZL1 has the perfect ride height for me. Less gap, but the gap is still there. Some lowering springs...even ones advertised as 1.25" drop seem to put the tire pretty close to the wheel well which is a look I do not like.

OP I knew your car was lowered but had no idea it was on ZL1 springs. Do you or anyone happen to know what the spring rates on the ZL1 springs are?

So far I think my top pick would have been Pfadt V6 lowering springs which are advertised to drop at 1" to 1.25", but honestly they look to be a tad lower than these ZL1 springs from the pictures I've been eyeballing.

If the rates on the ZL1 springs aren't too harsh, I may just consider them, as they are likely cheaper especially if I can find a used set.

EDIT: OK so I found this:

Quote:
The ZL1 uses solid 25mm front and 28mm rear stabilizer bars, along with a variable rate 70 N/mm to 45 N/mm spring in the rear; the front 27 N/mm spring rate is the same as an SS.
So it sounds like the rear spring is progressive? I'm seeing that the V6 rate is 25 N/mm front and 55 N/mm rear.

How much different would you say ride is compared to stock V6 ride honestly?
