Rear wheel 15'' dia x 12'' #

These are the correct wheels for the 908, Wheels are manufactured using period correct magnesium sand casting techniques, from our own patterns at the leading motorsport magnesium foundry and machined in house with the latest CNC lathes & mills. Safety beads are incorporated and machined to the industry ‘ETRTO’ standards, as is the rim diameter to ensure correct tyre fitment and sealing. These improvements over the original wheel permit the use of tubeless tyres. Once the machining processes have been completed all wheels are subject to full dimensional inspection on our high accuracy, computerised co-ordinate measuring equipment. RSR, 908 and 917 wheels are crack detected and subjected to a process of double impregnation followed by a final pressure test which ensures correct sealing and no air loss. These wheels have a backspace of 84.25mm.
