best place to buy blue m sport rotors

bmwchue · 02-24-2018, 01:20 AM

I have the blue m sport brakes on my f30 328i. Ive been shopping online for hours and having a hard time finding some replacements. So far i know that the front rotor for the standard 335i is the same so searching under that will help eliminate the 328i base and m sport rotors. The rear rotors are different due to the ebrake issue. trying to get some plain ones but if the drill/slotted price are not too much i rather get them.

just wondering where everybody is shopping at for the best price and quality. Thanks

Front should be 370mm for the m sport, 335i runs 340mm

I bought Centric blank rotors.
look for part#s 12534147, and 12354144. These are the 370 front, 345 rear. They do have the 340 fronts but not sure what the number is. These rotors have a black e-coated finish on the hats and vents. I paid around $300 for all 4.

That is the first time i recall seeing larger rotors on the rear than the front for a BMW:

Option (Factory upgrade) with S2NHA M Sport Brakes (blue colored):

S2NHA Variant 1: all not listed under Variant 2
Front rotor: 340x30mm (Millimeter) / Brake Caliper with 4 piston
Rear rotor: 345x24mm / Brake Caliper with 2 piston
