lowering springs ,Shock/Strut
 

is it best to lower my car 1.5" or 2.0" without having my muffuler scratch when i reverse out my drive way, and if i do lower it with Performance/Lowering do i have to change my Shock/Strut. thanx

If you don't want your exhaust scraping, it's safest to leave it as close to stock height as possible. You don't have to change the struts, but unless you like a shit suspension, it's A LOT better to change them.

the added pressure to your stock struts from lowering your car will wear them out much quicker. i say go 1.5", anything more you should get a camber kit and seriously think about getting new struts.
