My 95 Prelude SI has been having issues w the upper control arms hitting the body of the car. I had her lowered 2 inches initailly w Progress springs and 5 way adjustable tokico shocks. When the back rt. quarter panel got dented, I changed to Eibach Pro kit and new tokico shocks. I recentlyl put in poly. bushings and now the problems is still occuring. It's to the point now that the back quarter panels paint job is starting to fade in a straight line where the up. control arms are hitting. No one can figure it out! Could it be my Upper Control arm bushings/Camber kit? This is the original one I had installed w/ the 2 inch springs and they were squeaking really bad until someone used lithium grease to lube em up. Any answers????

 

My 94 rarely ever bottoms out unless I hit something terribly steep. That makes me think that something in your system is weaker than it should be for the weight of the car.
Just a thought...

 

who installed them? could you have bent parts? i once saw an 89 si and the bushings in the rear upper control arm fell out so the rear wheel was clunking around. i dont understand how the upper control arms could hit the top of the fender unless something was bent or missinstalled. you should take a pic with the wheel off and post it so i can actually see how everything is set up.

 

Here are some pics I have of my prelude. They are the camber kit(upper control arm bushings) and the upper control arms in the front. You can see the plastic wheel casing has been broken and is exposing the inner seams of the car's body.

I attached the pics, hopefully it worked
