Features and Benefits
The center diffuser reduces unnecessary drag by blocking air from behind the rear axle to prevent air from flowing into the inside of the rear bumper, and channels all air to the underside of the diffuser to generate strong downforce.
The cone shape of the left and right tunnels increases the velocity of the passing air and pulls the air from the underside of the body backward.
The left and right end panels are rectified to reduce drag by reducing wind-up to the rear bumper.
By creating a gap between the rear bumper and the diffuser and enlarging the rearward opening, the air flow on the underside of the body is improved, strengthening the downforce and cooling of the entire underside of the body.


Cautions for installing a diffuser
The diffuser cannot be installed on vehicles equipped with a stock exhaust or stock equivalent exhaust due to the different layout.
LAPTORR exhaust for E46-M3 can be installed.
