I performed a search and read through the various threads, however I'm still getting conflicting infomation, so I want to pose the question again as the answer may have been buried somewhere...
What is the total difference (in inches) that you can lower the C5 Corvette on stock bolts? Assuming the car is at normal height, what is the maximum amount (in inches) that the car can be lowered?
Also, is there a measurement per rotation or thread count to work against?
I was able to achieve 5/8" front and 3/4" rear on uncut oem bushings and standard length oem bolts. That's with leaving the rear bolts at 2-3 remaining threads under the clip retainer and the front with a 1/8" gap between the bushing and spring.
That's also within the range that GM recommended. Any more than that and you're into the realm of form over function. It wasn't my choice.
I got about 3/4" all the way around with the front bolts turned all the way and 3 threads showing in the rear.
Mine was the same, 5/8 in on the front and 3/4 in on the rear. Doesnt sound like much, but made a big difference in the overall look.
I'm curious why you didn't lower the same amount on both the front and back?
I would like to try and narrow the gap a little between the tire and fender, however I had previously lowered all the way on stock bolts and I was scraping everywhere so I raised it up again. Now I'm wondering how much a difference would be to lower it 1/2" or 5/8" all the way around?
3/4" rear & 1/2-5/8 front is about right, the rear I think will lower more,
I made a wooden gauge to check my wheel well heights, and set them at 27" front & 28" rear, easier than a measuring tape.
