Serpent announces the addition of a new version of the Spyder SRX4 4wd buggy with a new hard anodized 7075 T6 aluminum chassis! The carbon chassis, which is standard on the original Spyder SRX4, gives the car extra flex which works well on medium and lower grip surfaces. The new version with the aluminum chassis works better on medium to super high grip tracks. The durable 2.5mm aluminum chassis is stiffer than the carbon version. It is machined to make it lighter and hard coated for durability. Check out the pictures after the break.
