600845 Transmission brace alu RR SRX8
For the Serpent Cobra SRx8 Serpent now offers these optional lightweight machined 7075 T6 aluminum transmission braces.
As replacement for the standard moulded chassis braces, the aluminum ones are stiffer, and thus allow less chassis flex. Depending on track conditions and type of jumps you can choose to run both in alu, or just the front or rear, or in case of less grip run the moulded ones.
