The front part of the original undertray on these cars is notoriously weak due to its fibre material construction and as a result is prone to failure over time.

Our solution is a direct replacement, three-piece undertray made in aluminium that reuses all of the original mounting points to ensure a perfect and secure fitment.

Unlike others on the market, the design of the oil cooler extraction ducting has also been carefully considered to imitate the original in order to maintain sufficient cooling. As a result, the sides of the ducts are enclosed against the oil cooler and the radius of the ducting increased in size. There are also brake duct cut outs to allow the use of a GT4-style splitter with brake cooling ducts.

Finished in a high-quality black powder coat finish, the undertray offers improved strength, durability and cooling effectiveness.
