2007 BMW 335D E91 Brakes

netherborn · 08-09-2022, 03:50 AM

Hi,

I took ownership of a 2007 BMW 335D E91, about 6 months ago. The front discs now need changing. I noticed the discs currently on the car are larger (370mm diameter) than the standard brakes (300-330mm diameter).

I measured the discs on the car to be approx 370mm.

However, I can't find anywhere that sells 370mm front discs for a M Sport 2007 335D, they all seem to be 348mm.

Any ideas where to look for replacements or suggestions of cars that act as donors of 370mm brake discs to a E9x 335D ?

My 335D has been remapped to 370BHP so I would like to keep the upgraded stopping power. My 335D is not a M Sport out of the factory, although it has the bigger brakes discs and calipers.

Sounds like f30 brakes? Or M3? Not stock anyhow; I don't think either series or sport came with anything other than 348mm brakes on a 35d.

I would post a picture so an experienced person can give you feedback. In the meantime, I'd look at an online supplier like FCPEuro and search for front brake kits with appropriate sized rotors. I went with their Akebono/Zimmerman kit for my E92 and the brake dust is no more with very little reduction in bite. You can search the Suspension/Brake/Chassis section for specific recommendations on pads and rotors.
