First off, I have Ark GT-F springs installed on my car.

I had a set of MSR 045 rims mounted on 225/45/18 tires about a month ago and every now and then if I went over a big bump the back passenger tire would rub just slightly.

Just recently the rubbing seem to get a lot worse and I went out to take a look at my car today and the back passenger side of the car is sitting much lower than the drivers side.
(I was riding around with a large friend of mine a few days ago, he is 300+ lbs and the car hasn't been the same since!! haha)

What could cause this? Blown strut? Worn shocks?

I heard that struts and shocks would not affect ride height.

HELP PLEASE!!

 

sounds like big man blew your strut to me haha. any loud noises when you hit bumps or anything?

 

check to make sure the rear spring did not fall out of the seat. That can happen on lowered cars if you hit a large enough bump.

 

It makes noise once in a while, but I think that was my tire hitting my side wall.

 

umm well go push on the corners of your car and if the one that is sagging bounces/feels different then yeah strut
