I have a 02 SS with 18" rims 295/35/18 rear and 275/35/18 front. I took it to a body shop and shaved the inner fenders in the rear. i want to drop it I just don't know how much I'm thinking an inch. Any ideas of what I will need to make this happen?

 

Springs, shocks, LCA relocation brackets, adjustable panhard bar. Also with your wheels you'll probably need to remove the bumpstops (if they aren't rotted out already).

 

take the rear spring isolators out and see how it does. that should take er down about an inch. i was using hose on my springs but picked up some custom made isolators that do a better job of isolating vibration transfer than hose. i got about a inch drop maybe only 3/4

I have heater hose mod (as Craby described above) with stock rear springs, Summit front lowering springs, SLP Bilsteins all the way around, and LCAs, Relocation brackets, and adjustable PHB from Founders.

 

Just remember, dropping your car will trade some ride comfort for handling... That's one reason I did not do it, plus I don't want to bottom out MORE on the nose or exhaust!

 

all I did was buy the Bilstein shock and spring kit from Classic Industries. Its $800. It lowered the car by an inch as advertised, and I didn't have to do anything else to the car.
