Carbon Rear Diffuser - E46 M3

Regular price $1,099.00 Sale

The carbon fiber E46 M3 Rear Diffuser is race-bred and functional, but it's also perfectly at home on a street car. As with all of our professional-quality carbon, this piece is bagged and autoclaved to be extremely strong and light - surface finish is straight out of the mold with no additional weight or clearcoat added as is typical for our racing applications; you may choose to have your local body shop finish for ultimate aesthetics and UV protection for high-end street and show car applications. Our diffuser extends all the way forward to the factory rear fuel evaporation box, which provides the axle-back flat floor from the factory.

The diffuser attaches to your stock bumper trim mounting points, and it requires slight modification of the fuel evap. box, plus reversible modifications to the bumper.

Designed for use with the BimmerWorld E46 M3 Exhaust line - this exhaust section is designed specifically for use with this diffuser. The diffuser doesn't work with any exhaust section using the standard left cutout in the stock factory bumper insert.
