I might get rotors locally from NAPA since I'm not getting drilled/slotted rotors. The NAPA guy didn't know what diameter I need and there are three different sizes in his computer.

What are the sizes for a 2007 Cooper S?

Thanks!

 

stepping out on a limb I'm gonna guess those three are

original GEN1 (not JCS) fronts

GEN1 JCS and GEN2 front, these would be larger that the previously ment',
but the same rotors

and rears which I understand to be same on both GEN and smallest of all...

So the fronts you need are the largest listed and the rears are the smallest. How's their return policy?

..


most of all I'd go to a different parts store as when I recently bought pads and rotors from AutoZone I didn't have this problem. There was SOME decoding to do ... but we figured it out.

p.s. pads and rotors I got locally are totally FINE for everyday driving. My son was using the 02 to deliver pizza and we needed new, but not performance brakes.

 

Gen 2 Cooper S front rotor diameter is, 294mm X 22mm and the rear rotor diameter is, 259mm X10mm

 

I'd stay away from NAPA rotors had them rust and warp. That's why they are cheap.

 

Using the Ultra Premiums I've put over 40k on my 07 MCS without any warping or other issues- fronts were part number 880605, rears were 880604.

They also had wear sensors through Altrom, about half the price I was charged by my dealer.
