I went back to the beginning of this thread and looked it up. I was curious because AFAIK there is no such thing as a "stock" track width wide5 ball joint disc set.
Part #4501 is the Fast Fab truss bar setup. I almost bought their(Fast Fab's) filter mount with bypass, but ended up using JayCee, a very nice piece.
#4201 is the ball joint wide5 disc kit.
It says right there it's 7/8" wider per side. They recommend using a 2" narrowed beam.
I'm saying what I've always said, there is no such thing as a wide5, ball joint, stock track disc brake kit. CSP and Airkewld increase the track width by at least 3/4" to 1" total.
All the kits use a ball-joint drum spindle, and instead of a thin backing plate you get a 3/8" steel caliper bracket. That's the minimum widening right there. Then you've got more width, depending on packaging around the caliper/rim/disc. The hub has to add more width unless the caliper is thinner than a stock drum.
I'd like to see a wide5 disc hub that uses a Karmann Ghia disc spindle, this SHOULD allow a stock(or very close to stock) width.
Well that sucks. John assured me they were stock width. I bought them from his site after numerous emails with him. I had no idea it was a CB kit until it arrived.
But thanks for the info. I’m glad I found out before I installed them. Now that I’ve balanced them, there’s no way I can return them. $550 out the f**cking window.
