Increase the wheelbase of your TRF201 by 8mm with this CNC alloy extension set from Exotek. Featuring an alloy upper bulkhead with sturdy camber rod mounting and 7075 alloy T-plate for extra durability. The set adds 35 grams to the rear of the chassis in place of adding ballast and retains the use of the stock chassis for maximum traction due to the flex of the TRF201 chassis. Allows the use of your current body and wing. Exotek also offer a carbon fiber battery strap for the same car for that trick factory look.
