As optional parts Serpent offers the wishbones for the Serpent 747 now in a extra stiff and extremely durable composite nylon. The parts have less flex then the standard parts. Under very high grip conditions as well as under very high temperatures the parts will perform best. In many cases the standard nylon parts, with more flex, may perform better. As always all depends greatly on overall set-up of the Serpent 747 and driving style as well. Parts are indicated with a H (hard) for easier indentification. Available as separate parts and as full-set.
