Maranello have come out with a very radical new design for 2009, the RS8. It features a centrally located rear brake system and 3rd bearing with a floating disc, floating caliper, and floating bearing. The entire frame design is also different to anything else currently on the market. The tubing has a symmetrical design, no rear torsion bar (one fixed tube across the back), and a very interesting front end.
