I know the PJ5007 is the drilled hub medium in .830", not sure about the PJ5002.

I read a comment about the minimum rear tire OD for F1. Is it 0.812"?

F1 is different rear clearance because they drag in the bank.

Greg,

 

Out here we don't get to run nice high volts, only 13.3.

 

But we always use a 10, some even an 11 pinion. Spur gears, most use 28, some go to 10/26 with 11/28 an option and with any power with these thing the brakes are low. 

 

If you want brakes run the PS/FK and stop on a dime LOL.

 

Jason

Along with the drag strip type track, and slightly lower power( I run 13.5v), it probably helps you run no weight minimum, and lower downforce Can-Am bodies.

Do you gear differently for the Flat Track?
