Many Ford GT owners have learned the hard way that the factory rear diffuser is brittle and will not survive minor run-ins with parking blocks, large stones, or other normal road debris. Additionally, its function is limited in favor of styling, having been downsized from its optimum size and shape as to more accurately match the artists vision of what the car should look like.
Thanks to STILLEN of Costa Mesa, CA, GT owners can now have an upgrade made of durable urethane, far superior to the brittle factory unit, that can withstand the rigors of daily use for less than 30% of the cost of a factory replacement. STILLEN also spent hours upon hours and thousands of miles on the track to find the perfect dimensions for optimum downforce. The STILLEN unit is 4” longer than the factory piece to channel and decelerate the air underneath the car for more downforce at speed without any compromise to daily composure.
This product benefits from STILLEN’s 20 years of product development and urethane production experience and is a well crafted, better than OE product that is backed by a limited lifetime warranty. While most owners choose to leave the natural flat black finish untouched for an understated, race bred appearance, it can be painted to match any color scheme.
** DUE TO POPULAR DEMAND **
STILLEN has also created a OEM length rear diffuser for those opting to retain the factory look of the diffuser over the increased downforce of the longer piece. The OEM length diffuser retains the urethane construction and durability features listed above.
