[Z06] Lowered suspension sucks....

Lowered suspension sucks....
New tires installed last week and I thought I'd try lowering the car a little so it didn't look so 4X4ish.......Turned the stock bolts on the back down to 3 threads exposed and fronts to 10 threads exposed (just as a starting point)
Drove the car a whole day before pulling it back in the shop and putting everything right back where it used to be. Luckily I took note of the factory settings. Car rode rough, front end was dodgy and felt unstable at anything above 90.
I love the look of them lowered but can't stand how it drove.

you have to do all 4 corners and you have to do it right. 1/2" down from stock is still very good for compliance and it looks a bit nicer. measure from multiple points before and after. the drivers side ideally will be 1/8Th of an inch higher than the passenger
it is slightly stiffer than stock but you still maintain good compliance which keeps the car fast. these guys slamming on stock bolts just wind up with a slower car that rides rough

Next he'll complain his tires suck when he installs them without balancing...
I've had several slammed C5s and one slammed C6 without any issues when done right.

Refer to my thread I recently posted

Actually yes it was done right....Measured at several points on the frame to make sure each side was close in measurements. It's more along the lines of the shocks were not happy with end result. Did the car need aligned-yes but no reason to run that out if it's going to ride harsh. Which is not what I'm wanting.

you also have to do an alignment as the tires toe out when you go down
if you live somewhere rural where the roads are bumpy the car is likely fastest at the stock ride height. you need all the compliance you can get

My experience is definitely opposite of yours. I noticed a negligible decrease in ride quality through about 80 miles of driving. I'll drive it another day or two to let it settle, check the rake, and then align it.
#11
If you don't mind, what measurements are you at on the frame, at the jacking points?

It's 4.5" at the Passenger Front, 5" Passenger Rear jacking point. This is about 1/2 inch lower all the way around than stock.
Fender Measurements:
DF: 27.25"
DR: 28.25"
PF: 27"
PR: 28"
I probably should tweak the driver's side slightly. At 180lbs, I doubt I smash the car 1/4inch.
I'll try to align in it in the next week or so and update you with where its at.

it looks like you spent some time on the lowering. took me around 3 hours to dial in. it doesn't go quick if you're particular and trying for a really even job

Going to give it another try. Starting off measurements:
DF 5 13/16" @ jack point
28" to fender
DR 5 9/16" @ jack point
28.5" to fender
PF 5.5" @ jack point
27.5 to fender
PR 5.5" @ jack point
28.5" to fender
Some of the front measurements are off as I don't believe it had enough drive time to settle after putting back to factory.
DF 5 13/16" @ jack point
28" to fender
DR 5 9/16" @ jack point
28.5" to fender
PF 5.5" @ jack point
27.5 to fender
PR 5.5" @ jack point

IMO I think that maybe you overlooked the fact that your original shocks are worn and need to be replaced. On lowered cars some shocks work better than others. I have Bilstein Sports which are a popular choice on lowered cars and seem to work well. You might want to consider changing them soon, especially if you are going to try lowering again.

Lowered it even turns on each side, front and back. Need to fine tune a little more but here is where I'm at:
DF 5 7/16" JP and 27 7/16" fender
DR 5.5" JP and 28 3/16" fender
PF 5" JP and 27" fender
PR 5 1/8" JP and 28 1/8" fender

After:
DF 5 7/16" JP and 27 7/16" fender
DR 5.5" JP and 28 3/16" fender
PF 5" JP and 27" fender
PR 5 1/8" JP and 28 1/8" fender
