T.O.P. Sabre S4 soft carbon fibre upper deck
Successfully tested during the 2014 TITC race and available now is T.O.P. Racing’s soft carbon fibre upper deck for the Sabre S4 touring car. The optional top deck makes for an overall softer chassis setup and is helpful especially in high speed and high traction conditions.
