Xpress XM1 239mm WB conversion kit
Coming from Xpress and made for the XM1 and XM1S M-class touring cars is a 239mm wheelbase chassis conversion kit. Designed for high speed tracks or in situations where stability is required, the long wheelbase conversion will help gain more stability by having a car less willing to rotate in the corners. The result is an easier to drive car that is also good on very high grip carpet. The kit includes new upper and lower carbon fibre decks as well as longer belts.
