This high quality 996 GT3, GT3 RS or CUP style splitter is made from dual layers of Kevlar for a durable and flexible part. The team at GT Racing extended this splitter to add extra down-force based on many customer requests. If you need it to be the stock length for a stock type of class for racing, just simply cut the additional piece off the end of the splitter. This splitter is designed for use with the GT Racing GT3 style front bumpers (#661E, #661L early and late style GT3 bumpers). This splitter can also be used on original style factory 996 GT3, GT3RS or CUP bumpers.
