I bought mine from their with the polyurethane washers and they are MUCH better than the Symborski kit which is clunky and overrated, metal on metal is not good, the urethane works great. Plus, it's only like $15 or $20, I think I spent $190 total with shipping from Road Race and they had great service and I got it real fast. Good luck.
