I just lowered my M3 with Blistin Sport Shocks and H&R sport springs. and the driver rear tire is rubbing on the fender now. my tires are 245/45. what should i do to fix this problem!
I know my tires are too tall but could i just get shorter ones to fix this problem.

Or you could roll the fenders, it's actually pretty safe if you're careful. Frolf's friend did it to his e30.

Everyone else here will say "that's a bad idea" or "why would you do that," they are all conservative when it comes to BMW's. Truth is rolling the fenders is easy and safe, just dont be dumb. Check out a BMW site with people who are more into 'tuning'

ture, but how much of a difference is a 245/45 to a 245/40 on side wall
For 18" wheels, a 40 is .97" smaller diameter, or about 1/2" additional fender to tire clearance. Certainly could fix the problem. Play with the numbers HERE

Contrary to your statement, not EVERYONE here would say rolling is bad and are conservative when it comes to BMWs.

Rolling is OK if you have the right tool (not a vise grip plier) and you know abit about body work and paint.

I was taught that any sentence that began with "everyone", "always" or "never" was usually false! I agree with you Kirby!

well i just went and looked at it and it seems to be rubbing on the inside of the wheel well ever so slightly so im still thinkin my best bet is to go with a smaller profile tire. Plus 1/2" is a lot all around the wheel

I would suggest changing the tire instead of rolling.

I went max wheel & tire size and rolled fender but still rub occassionaly with dips in the road. I'll rub turning corners if I have passengers in the car.

Mind you, sedan has less clearance than coupes & M3s. I'm running H&R sport, OEM shocks with 19 x 8.5 // 235/35/19 in the front and 19 x 9.5 // 265/30/19 in the rear.

SPRING PADS

ROLL YOUR FENDERS


epj doesn't remember, but i actually rolled my fenders myself with the proper tool. i didn't even use a heatgun because i went super slow, got the job done with zero paint cracking. you have many options before you swap tires (which would be expensive) springs pads are cheap though

Pardon my ignorance, but what exactly is rolling the fender?
In the inner fender / wheel well area, there is a lip that sticks out. This does not touch the tire based on OEM setup.

But because tuners / modders love the drop (lowering the car), and adding bigger rims and in my case, maximum tire size to fill up the wheel well, then you get "rubbing".

To solve this, but not a guaranteed solution, is to roll the fender which if I'm not mistaken will give you no more than an extra inch of space in the well. A special tool is used to roll the fender, basically pressing that inner lip against the inner wall fender so the lip no longer sticks out. Some shops do it properly, some do not. And as frolf mentioned, if the shop is careless or inexperienced in rolling fenders, they will crack the paint.

Usually the cost to roll a fender is about $60-80 p/ fender. here in Toronto its about $80CAD p/fender.

Hope that wasn't too confusing.

This picture should help explain it. Feel the lip under your fender. The tool rolls the lip back further, a bit at a time, so that the tire will not hit the lip.
