I know everyone here lowers their cars, but I want to raise my car about 1" front and rear. This is for ground clearance issuses from putting dual 3" exhaust on. The car is mainly going to be a weekend car and for the strip.

 

yeah 3" true duals would make things tight.

Pep boys and prolly other places sell extra thick spring isolators..try them.

 

You can buy aftermarket springs in virtually any diameter, height and rate you can think of. TRW (and others) makes a massive selection. If you're more interested in a good drag launch than carving corners you can get the right rear in a little higher rate (stiffer) than the left rear.

 

Here is a good place for spring information:
