I have a prokit on the car and NEVER rubbed but tonight I had passengers in the car and I heard a grinding sound from the rear every time I went over a dip or bump in the road. I have had this package for over a year and had these people and tons of stuff in the car a lot with no issues before tonight.

Yes she is a fat chick but could that really be the problem?

Is it rubbing, or is it something else?

I bet you a dollar next time you drive alone it doesn't make that noise.
Your rear spring rate is 171 lbs/in. Let's dumb the math down a lot. A LOT. Girl weighs 171 lbs, so the corner she is sitting on is now an inch lower. This isn't really the complete truth, but you get the idea. My only tire that ever rubs is the right rear, and only with passengers in the back, while driving over bumps. I've got stiffer springs, but probably wider tires also. You'll be fine unless you drive around with that much weight in the car on a regular basis.

Alright thanks guys. Thats around what she weighed, hopefully its not the shocks. I was only suprised because it never did that before with those two people in the car.
