I recently put 20" rims on my bonne problem is now when I hit bumps rear tires rub slightly is there any way to adjust hieght control sensor to solve problem if not any other auggestions

How wide and what profile are these tires. 20" wheels end up making the over all tire much taller then stock. There'* only so much room in the wheel well.

Tires are 245 35 r20 there is about 2 inches clearance above rims standing still but when I hit small bumbs they rub

Although a bit wider then stock, the over all hight is about the same. Might want to check your springs. They do have universal ride hight kits. Using that would limit travel a bit.

There is 2 cheap fixes for that.
#1 there are hard rubber Spacers that u can purchase. they install in the strings themselves. they decrease spring movement but stiffen the suspension. but i have heard that they fall out sometimes.this is the link http://www.jegs.com/i/Mr.%20Gasket/7...0002/-1?CT=999

#2 they also install on the springs. they are a reverse clamp deal. you install in the spring and tighten down, they spread out and keep that part of the spring from moving so the car doesnt bounce as much when u hit bumps. A buddy of mine has these installed on his 98 grand prix with 20'*. I seen the before and after and they really do work.

Hope this helps.

Do you have the load leveling suspension? If so there is a rod/lever on driver side rear wheel that is used for measuring. It is not adjustable but if you shorten the rod it will make the back ride higher. (I think shorter!!!!) This fix or any of the others will not keep the tires from rubbing, they will just rub less often and only on bigger bumps.

My buddies GP rubbed bad with the 20s partly due to sagging rear springs and really wide tires. the above mentioned (adjustable spring spacers) cured all. no rub at all and ride quality didnt change much. just my 2 cents and experience. All my buddies run 18'* or bigger. If they dont run airbags then they use these adjustable spring spacers, and swear by them



Including a buddy that has a 09 Charger on 24'* and a 300c on 24'*. If there is one thing i know its rims and fitment.
