Lowered Mustang Wheel Rub Problem.. Help Please!!!!!!

[drummerboy5.0]

Hey everyone..

My car is a 1990 GT, and i am running the 17x9 Cobra R rims with 45 series tires.
With the stock suspension, the wheels rub when turned sharply on the front valance.
when hitting a large bump, the top outer edge of the front tires used to scrape on the inner fender, a problem i solved by pounding in the lip on the inner fender with a small hammer.


I am ordering the BBK Gripp progressive rate lowering springs and a set of tokico HP's and that should drop my car an inch and a half.

My question is...before i install all of this..
Will I have more problems with the 17x9's rubbing the fenders or the valance?? and if so, would caster/camber plates solve the problem? or rolling the fenders properly?

anyone's opinion would be killer!!!

if they rub at the higher level they will rub when you drop the car lower. cc plates may help. maybe 91 to 93 fenders may help since ther have a wider wheel opeinig.. who knows..

What he said^^^^^^ What size tire are you running up front?

what they said^

And what is the exact size tire you are running?

its def the smaller fender openings....on my 90GT it rubs on the drivers side where you said, but not the passenger side...the reason, is because somebody a long time ago repaired the passenger one with a 91+ fender....its more roomy.

I did roll the lips and it helped.

i assume your running a 245/45 or less...if not thats your problem

That is odd. I have the early fenders on my 81 and 17X9's with 275-40-17's do not rub and 17X8's with a 245-45-17 do not rub either. I have the Steeda Sport Springs.

Well, if you lower it the problem will only get worse. I would just leave the ride height alone.

my exact tire size is 245/45/ZR17 .

I don't really want to change the fenders and try and color match the new ones. I'll cross that bridge if it is the only option, but it sounds like too much of a PITA in my opinion

Lowering is nly going to make it worse, when I had 17x9s at all four corners i would get rubbing on a hard bum or if I had the wheel cranked all the way.

I wouldn't change the fenders either. Keep your car as original as possible. You could always take the molding off, cut the fender and buy the 91-93 GT moldings.
