Hi there, though I have not lowered my car yet I have pmed a few members who have, 2006Corvette lowered his corvette and said that he drove the car like normal and it feels the same as stock. 1 inche seems to be a safe limit for a non show only car, you will scrape your front air deflector but i checked out the price GMs sight and its something like 15 bux, so ill just replace it as needed. Also remember to get an alignment after the lowering. Hope that was helpful
Im still kinda hazy on the lowering process so if you could post a DIY id really appreciate it.
As for the sway bars my motto is if your going to mod mod with the best, dont get something slighty beter just to have changed parts (like longtube headers as oppose to shortys) that being said pfadt suspension compenents is your best bet. Midnite902 just wrote a review, he was really impressed.
