is it legal to spin the arm on a lathe and touch a file to it to smooth out the stack
not cuting the stacks just smoothing it out
doesnt evan remove the green on it just gives it a little shine and increases rpm and eff.

In most spec classes this would be illegal....you would have to check with your Race Director but I would think they would outlaw it....

Either that or it's a heck of a speed secret you've just let out! lol Check w/ your race director.

if it's not listed in the rule book, it NOT legal.

That would not be legal for ROAR stock.
