What are some good adjustable shocks

for the rear, i want to stiffen the back end so it stops rubbing against my tires

Koni or Hal are really your choices. I have Koni's and really like them. But, I have to ask, where is it rubbing? And is there another way to stop it? Stiffening the shocks will reduce traction. You should be able to roll the fender lip and/or tweak the inside of the wheel well with a body hammer (just make sure the back seat is up).

The lip of the fender keeps hitting the outer edge of the tire, so maybe rolling the fender will work, Im going to try that first. But I dont like the fact that the car bounces that much where the fender would rub the tire

comp engineering is what i would get.....

comp engineering shocks?
