Rear an element of the split top deck. The split (2 piece) top deck is preferred primarily for asphalt tracks. The graphite top deck features milled holes for unique tweak-free top deck screws. The very best deck provides more steering response, and much more on energy steering. The flex attribute varies versus kit top deck, as well as the 2 pieces enables more flex options, and this can be modified individually in the middle of your front side and backside. Machined from 2.0mm graphite product, the form of this top deck had been specifically designed to reach optimum traction and great steering traits at exactly the same time. The highest deck might be connected to the engine mount utilizing these alternatives: 1.) smooth establishing - just one back screw is required. This permits maximum flex and provides maximum steering. But the car is less stable on-power. 2.) Stiff setting - Both screws are employed. This environment provides paid down flex both ahead and right back. Mid-corner steering is reduced, rotation is paid off. This environment provides maximum security and makes the car easier to drive.
