No, those have been put on hold for changes...stay tuned
A wing shim (alloy or plastic) is recommended so the mounts can't spread under hard impacts.
I feel the reason they haven't released the aluminum front and rear hubs for the b5m is because associated has something new in the works. either a new car or and updated one that the current parts wont work on. they showed these parts back during the offroad worlds. there is obviously a reason they have put these parts on hold. maybe PW will enlighten us. im sure he knows alot more than we do. just my thoughts.
