rear

Has anybody raised the rear of there car a little so it gives the car a drag look any pic's. i have 295's 60 15's in the rear and 215 65 15's in the front and just thaugt it would look better with the back up higher or the frot lower but i dont think i could make the front lower.

I cut my front coils to lower the front by 1 inch to give my car some rake. It looks really good and it's better than raising the rear. To raise the rear get a spring rubber like they use in NASCAR and put it in, it effectively increases the spring rate and will cause the car to sit a little higher, but I wouldn't do it.

Sure you can...just go but a new set of rear spring isolators from GM and it'll jack it up about 1"- 1.5". Here's links to what my car looked like before and after. Good pics in the second link:

Air shocks are not a good idea, the shock mount is not built to handle that kind of loading. Running air shocks has been know to tear the shock mount out and ruin that area.

I'd cut the front springs alittle, start small and keep going till you get where you want. If the rear need a little lift, add new coil insulators.
