Came off the track after 7 minutes at 112 degrees. Fastest lap 11.06. Just ordered 56, 57 and 58 pinions. PRS was out of stock on 59 and 60 or I would have bought them too.
Wow...I'm hoping they have pinions that high at the shop. I didn't expect to need any that big and don't have time to order some before leaving for the IIC.
