Our Lexus IS series carbon fiber rear performance diffuser. With over 6 months in the making, we are pleased to announce the world's first true bolt on replacement carbon fiber diffuser for the 2nd generation Lexus IS series.
This beautifully finished pre-preg full carbon fiber part replaces the stock plastic rear under tray, and reuses all plastic mounting hardware. This part can be installed in as little as 10 minutes with only a socket set and flat head screwdriver, simplicity was key when designing this part, as absolutely NO modification is made to a stock vehicle for installation.
Our original intentions for designing this part were strictly for cosmetic improvement. However, down the road in R&D we decided to use our state of the art advanced CSWT (Computer Simulated Wing Testing) software that we have previously used only for only our private label race team aero parts that we manufacture and test or 3rd party testing that we provide for other companies. With only a few tweaks to our original design we were able to create a forced channel of air to flow smoothly through the 4 strategically placed fins. The result equates to improved high speed stability and reduced rear end lift. Make no mistake, this is not a true race only diffuser, this was designed for street or track use for improved looks as well as the 2nd benefit as an aero improvement, perfect for the HPDE driver!
