I think is the 20" rims like someone already point it out. That is why I will stay with 19" even that the tires are more expensive.

Perhaps you're blaming the brakes for normal vehicle dynamics. Brake hard while slightly turning or cresting a hill and the back end will squirm. It's just a matter of the braking causing forward weight shift and the back end getting light. Happens all the time on the track if I'm braking for a corner from a dogleg straight.

And everyone please stop blaming wheel spacers for your problems. I've run spacers on my car for two years and multiple track events without a single hiccup.

1.Dissassemble brakes, resurface both rotors and pads using sand paper then reassemble and performing bedding procedure. I usually do 40mph to 20mph quick braking(do not lock up ABS) 3 times then follow with at least 2-3 60-30mph quick braking to bed.

2. If your running very wide tires they will obnoxiusly tend to pull to the lowest point in the road no matter what you do, keep this in mind.

3. It is possible that your alignment may be out, there are any number of reasons that could cause it but probably noting that your car is new the tow/camber may be slightly off kilter. This is the last thing Id check as seeing as you just had the brakes and rims installed your problem more then likely rests with one of those two.

Did you over tighten lug nuts?

Bed in brakes properly???? Also if you over tighten the lugs it can cause warpage.

its was the camber on the rear tires/control arms plus new tires with wax on them! adjusted the camber and it feels good! no issues as of yet!
