Hey guys listen I decided to see if i could get some help here on the fest!

Look I had these style 5s and I never had this problem with the style 5s on my car and I decided to upgrade to the M3 Wheels which are 19 inches ( pictures attached ofcourse) :) everything is perfect but here is where im stumped!!

THE BRAKES SQEAL! lol I changed changed the pads and rotors and sensors with like 3 different combinations already but it still does it. I even pit disc brake quiet on the back of the pads, still does it! Now mind this is using the 528i original brakes. So my question is!

Is there something in this world I can do or is it because I need a big brake kit.

The reason the big brake kit come to my mind as a solution is because (my mind) thinks that since the wheel is bigger and the circumference is greater it need more surface area for pad and rotor contact, and right now its not getting it lol

I dont know if im right or what but maybe someone can help ... actually.. please help me.. no .. i didnt say it right ... I meant to say PLEASE I HELP ME !!!! I WILL LOVE YOU FOREVER !!!!:thumbup:

going from style 5 to those M3 reps, is actually downgrading the car.

Agree :thumbup:

Have you tried to find rubbing or getting tires rotated even, I'd try slamming on the break from going about 15-20 mph.

Are you sure there is no contact between the wheel and calipers? or contact between wheel weights and calipers?

And you used brake grease on all the pads contact points?

edit, you made sure to to apply the grease on ALL the contact points not just the back plate of the pad?

Maybe u have bad wheel bearings. The rotor is attached to one side and the caliper the other. So if the bearing is loose and the wheel wobbles because os it the rotor will therefore slap around inside the caliper. The larger wheel my have increased this as there is less rubber to mush to road variations.

Told you to try out the pencil led thingy. It's old school, did it in the 60's and 70's.
