Something i am always looking at is new materials to use with the atomic-carbon stable of cars
Below is a kevlar / carbon fibre tub chassis for the S4 which Mat Dodd is testing, the chassis has a outer layer of kevlar and the normal inner layers of carbon fibre, the kevlar should help reduce any wear to a minimum on the chassis, and also doubles up as a small bullet proof vest in emergences lol. The only draw back is with kevlar is that when you do wear down to the kevlar it can get hairy.
Depending on how testing goes it might be introduced on the S2 / S4.
