BMW 335i (E9X) Performance Parts

Parts confirmed to fit the 2005–2013 BMW 335i (E90/E91/E92/E93), including xDrive cars. The non-M E9X chassis.

GiroDisc two-piece floating rotors and replacement rings, front and rear, plus a Moroso aluminum coolant expansion tank.

The 335i makes serious power for a car that left the factory with modest brakes, which is why it is the first thing owners outgrow once the car is tuned. The plastic expansion tank is the other known weak point on this chassis — it goes brittle with underhood heat and splits, usually without warning. Both are worth doing before a track day rather than after. Installation available at our shop in Andover, NJ.
