Thanks for the advise guys. I've decided to stick with the BJ4WE but modify it slightly to accept B44 parts (since they are readily available at the on-site hobbyshop at my local track) of the more commonly broken parts such as the front arms and the front CVDs.
I'm going to buy the B44 front CVA (I don't know what makes it an "A" then a "D"

), front castors, and the front steering knuckles. The whole front end of a B44 seems a lot more solid then the BJ4WE's default, even though the front arms looks to be about the same design structurally.
I think this would mean cutting the hinges down to be shorter length-wise, in order to accomodate the taller lower hinge on the B44 front arms... I think once I get the castors and the steering knuckle, there should be no reason why the B44 CVAs would not work. The B44 hex adapter that comes with the CVA kit is a nice bonus for this mod, since the Rulux wheels requires these...
I'm going to continue racing my BJ4WE, I really love this car. The only thing left to get would be the front sleeves for the hingepins. I'll probably stock up on these. I've never chewed one up but I'm always afraid of it getting worn out and the arms becoming wobbly...
Who here still races their BJ4WE? Do you guys in England race the B44 instead of the BJ4WE now? I know many of the guys here in the states have switched over to the B44... I'm just not ready yet
