BMSPEC Rear Diffuser v2

Reduce lift and drag with a sleek, functional rear diffuser.

Execution is everything. Diffuser-V2 takes a well-proven, effective design – the 7- 10 degree flat diffuser – and adds exhaust clearance, modular strakes, and a huge dose of style to a wide range of cars. Features:

  • Functional: Diffuser angle is CFD-verified to reduce drag. Our diffuser reaches all the way to your rear subframe, to avoid the parachute effect and smoothly guide air out from under the car.
  • Modular strakes (fins): The aluminum strakes come in three variants to suit your taste and usage. They’re removable, so if you break one you only have to replace the one!
  • Adjustable: The diffuser mounts come with either shims or holes to adjust the height and angle to clear exhausts, bumpers, etc.

Diffuser-V2 can be made to order in either fiberglass or 3k twill carbon fiber. Currently supported applications:
