The back of the car will be instantly recognisable to anyone who has built a Tamiya 4wd of late. It uses the suspension balls on the inner hinge pins, with captive outer pins. Upswept rear wishbones. The only part to take care of, in building the rear, is the left rear hub goes on the right, and vice versa.
The rear suspension hold is sandwiched between the gearbox and the chassis, but it is not integral part of the T-Piece.
One little tip, if you smear a little Ceramic Grease on the screws, they thread in nice and easy on the hard graphite plastic.
One note, the rear wishbones, although similar in design (and obviously metric and not imperial), are slightly longer than the B4, as seen in the pic below (Tamiya item is the lower one).
The rear shock tower is quite a substantial item, it interlocks with the chassis, and there is a brace that goes from the tower to the gearbox. It also has mounts ready for fitting an anti-roll bar to.
Once assembled, the drivetrain is very smooth and notch free, the suspension has no binding in it either, and like all Tamiya cars, you can buy shims for the suspension arms when they become a little worn.
