i used the proline ones, bit tight but work perfect. the 18 degree c-hub is making the outside tire turn more because i was running 2 degree toe-in in the front. now i can use some toe out and have a bit more control coming out of the turns, sweet. had the st out in a mudded up track and it ate up the clutch shoes, locked up on the third tank. gonna switch to the stock wheel and shoes and see how that goes.
