Just to add a bit more to the BB fitment.
I have just tested my Yokomo BB shocks from the BMAX4 Factory 2011 kit and they fit perfect, bar a small adjustment. Please excuse the dirt, as our track was wet, and i havent cleaned up the car. Im all for presentation when i come to the track, for the first race at least.
Taking into consideration im using the anodized front shock tower, the front shocks will need a spacer or nut to space them back from the tower so you get full travel and use of the inner hole. They do not bind in any way, and have the travel and droop that I want my B4 to have, Full lock left and right also no binding on springs.
The rear shocks will need a small piece taken out of the top of the shock mount (with dremel) wont need more than 2mm just so you can use inner top hole. Other than that, no binding in any other holes, the turnbuckles touch the springs by the slightest (i do mean slightest, can slide a piece of paper between) but dont have any restriction on the shock. They are the same length as AE V2 or the RTR Blue. Has a nicer feel, and damping properties, although I am only using 30 and 20 wt oil at this time.
Sorry to the other guy who may go NUTSO...
