Spec-R R1 motor mount, chassis & top decks
New from Spec-R for their R1 touring car is a new motor mount support and new style graphite chassis and top deck. The red anodised machined aluminum motor mount now features an additional mounting point for the new top deck for different flex characteristics. The new top decks are made from 2mm thick graphite and come in narrow and wide versions, while the new chassis plate is made from 2.25mm thick graphite with a new profile which all together helps provide faster response and more traction.
