Just Found a awsome way to put the bb shock rubbing up against turnbuckle problem. It's a $4.00 fix that can make you shocks 1 look good also can get rid of all play what's so ever in the rear. It's the plastic rear hubs for the b4.1. Since they come unthreaded you can put the ballstud in whichever side you want to i decided to put them in backwards and place the turnbuckles backwards and also buy buying these hubs means you can get rid of all the slop since you don't have to use the aluminum ones anymore that slop out after about 10 races.
