Serpent have introduced new option parts for the Cobra SRX8. First up are two suspension weight set. These brass 15 gram weights are designed to fix to the bottom of the rear aluminium uprights instead of the standard uprights are made in 7075 T6 aluminium. The extra weight will help on tracks with less grip, to improve traction. Next up are the lightweight 0mm and +1mm offset wheel hex adapters. The offset wheel hex adapters are made in 7075 T6 aluminium, hard anodised and laser engraved. The grey anodised wheelnuts are superlight and feature serrated bottoms to make sure you dont loose them easily. Also new are the lightweight aluminium wheel axles. They are machined from 7075 T6 aluminium, hard anodized and they are 60% lighter compared to the spring steel standard ones. Available by 2 pcs with hardware, so 2 packs needed for the whole car.
