way too high for us. this is carpet.
www.mikeshobbyshop.com and go to the new track cam. it is 3 pieces of ozite with i think 100' back straight. I have run up to 85mm, but the car was not quick enough out of the corners. I found that with the novak on our track 80-81mm was the fastest. also I am running tires in the 44mm range. I think if I go down to a 42mm rear tire, that I should be able to run a 84mm or so. the taller tire take more for the motor to turn the extra meat.
