I have 18" y2k and 275/35 tires. How much can I lower my car? I would like to go an inch and a half if possible.. also do they sale kits that lower the front more than the rear. I would like to lower the front 1 1/2" and the rear about an 1". let me know

 

oh yeah I'm doin this to a 99 ss if it matters

 

You can lower it 1.5" with no problems. Get the Eibach pro kit, it'll look & handle a lot better. While you're at it look into upgrading your shocks, the stock ones don't do well with lowering.
