REAR DIFFUSER for E46 M3—PROTOTYPE
The prototype has been completed.
The design is mostly complete, but we'll start production once we've made some minor adjustments.
This product is scheduled to be available in wet carbon only.
It consists of two sections—the upper and lower—and the upper section replaces the stock rear bumper cover.
The lower section is suspended, with its front edge extending to the canister cover to generate downforce, while the side panels wrap around to the outer edge of the bumper, creating a design that balances well with the volume of the GT wing.
This product can be installed on vehicles equipped with the LAPTORR EXHAUST E466M.
Scheduled for release around January–February 2023!
