The 340 and 370 calipers have identical pistons but the castings are stretched out on the 370's to accommodate the larger diameter rotors. On the used market you have to be careful because there are lower model F30's that come with blue front calipers that 340, not 370. With the F3x 335/435 it's easy to tell by color if you have the grey standard brakes (rotors are front 340mm x 30mm/ rear 330mm x 20mm) or the blue M Sport brakes (rotors are 370x30/ 345x24). I will look into those and probably place an order tomorrow.īMW causes a lot of confusion with how they throw around their marketing term "M Sport" on their various models. The hawk 5.0 pads sound good, anything with less dust would be great haha. I'm hoping I don't need rotors right now but if I do I'll look into those too. In the future I may upgrade to those brake lines you suggested. Which makes sense now because the stopping power of my brakes never impressed me. Didn't realize the m-sport brakes were blue. Thanks! I added the car description to my first post (2013 bmw 335 x-drive sedan m-sport package) I assumed I had the m-sport brakes since I had the m-sport trim package. I can't recall the M3 rear brakes off the top of my head. So the F30 and F80 would use the exact same front Hawk 5.0 pad. M3 uses 380mm rotors because it has a different mounting point than the F30 which uses a 370mm rotor. It's got "370/380" in raised lettering on the back of the caliper. The M3 uses the exact same Brembo 4-piston caliper as the F30 M Sport/M Performance caliper. But a guy who owns an M3 recently drove my car and raved about my brakes, for what it's worth. I can't really answer your question with authority because I haven't driven that M3/M4 or researched the compound used in its stock pads. How do these feel compared to the stock F80/82 M3/M4 brake pads? (Brake dust not being a factor.) Watch excellent YouTube videos from Kies Motorsports to learn a lot about your car. If they are front grey or blue Brembos I have attached photo for Hawk 5.0 part numbers. You don't say which model car or brakes you have. Much more solid brake pedal feel! See photo for F30 part numbers. Upgrade brake hoses to stainless steel brake lines like StopTech for $106/set. Much less expensive than BMW rotors.Ĭhange brake fluid every 2 years. Highly recommend Zimmermann rotors which are high quality German rotors better than OEM because they are zinc coated against rust. Dust is light in color and washes off easily. Great bite, heat up instantly and light dust. Low dust is a pro but make sure that you know the cons are that they are slow to heat up to work and their bite is average. Welcome to the group! As soon as you mentioned dust you will get recommendations for ceramic pads. The stock pads (I assume the car has stock pads on it) leave a ton of brake dust! What are the best options for some low dust pads that have similar stopping power to the oem pads and where's the best place to buy them? Just hit 60k miles today and now I'm getting a strong squeaking when I come to a stop. Recently purchased a 13' f30 m-sport with 54k miles.
