For the Spyder SRX2 MH we offer this optional 2mm carbon fiber chassis.
The carbon chassis can replace the hard coated aluminum chassis, as the alu kick-up is separate from the main chassis. The carbon chassis fits without any further modifications. The side guards as in use on the alu chassis, fit right on. All 4 transmissions fit, 3-gear standing and laydown and 4-gear standing and laydown.
The carbon chassis is lighter and has more flex, which may help handling at higher traction surfaces.
