Factory bolts drop
hey guys I tried doing a search but didn't come up with anything. What's the lowest recommended drop when using the factory bolts and not swapping over to coilovers ?

"Recommended" is going to be subjective. Lowering the car via stock or aftermarket bolts reduces your shock travel, and makes the car more prone to bottoming out.
My advice, is just to drop it all the way down on stock bolts without cutting the rubber bushing on the end of the bolts. Usually nets about 3/8" - 1/2"...subtle but noticeable. I don't recommend cutting the bushing to get that extra ~3/8" drop, nor do I recommend aftermarket bushings as they all eventually fail.
Also, any change in ride height necessitates an alignment after the car has settled in.

cool. thanks for the input. yes. I'll do that then. I don't want to cut into any factory parts. also, when you say alignment AFTER CAR SETTLES, you mean I should drop, drive the car some time THEN take it for alignment?

Yes MTP is correct and I agree. And yes you should drive the car a bit to let it settle into it's new position before determining how much it has lowered. And then get it aligned - which most Vettes need done anyhow.

Wouldn’t recommend lowering bolts. I have the VMS lowering bolts and my car is pretty low and it doesn’t drive all that great. The VMS bolts are made of delrin so theyre holding up fine after 5k miles. My main complaint is noise! These things are noisy! Makes my Z06 sound like old piece of junk. The pads just rub the aluminum lca and just creak and clunk on any bumps. Can’t wait to get my coils and do it the right way.

GM also engineered the suspension to be in the "sweet spot" at about half inch lower than delivery height. So technically...lowering all the way on stock bolts puts you there.

Sorry to bring up an old thread, though I've lowered down as far as I can go with stock bolts and would like to attempt to cut the sock rubbers. Is there a way to do this with the bolts int he arms or do they need to be removed to accurately cut them?
