looks pretty heavy but a cool idea, had lots of wobbly wheels that are tough to straighten by adjusting nut pressure

Zen Racing introduce this diff hub set for 1/12th on-road chassis. The set has been designed to give 1/12th rear wheels a more positive lock to eliminate wheel wobble. Also with the addition of the left hand clamp spider the rear axle weight is far more equal aiding better drive forward and a better balanced rear axle. The hubs also make use of M2.5 screws over the conventional 4-40 fasteners for an easy and simple use track side. All parts are also available separately.

how is this different from regular hubs? more screws clamping it?
Sorry i first glance i thought it was something else...
However the hub and the clamp look like there are two separate pieces with long screws. the M2.5 screws are a welcome change in my opinion as well.
I have seen this a lot lately with the F1 cars. People are adding extra weight to the left side of the axle to balance the rotational mass. Supposedly it helps with forward traction, and the diff is less likely to, well, diff, when you going in a straight line under heavy acceleration. I am sure alittle extra weight on the axle wont hurt in a low grip conditions, but in high grip I would think that I would want a light rear axle as you already have tons of grip.
there is also a "locking" spur gear out too. It allows the balls to move around inside the holes to make it lock the axle under acceleration, then when you decelerate the balls move back into position and all the diff to operate. Neat concept, but I don't know how well they would actually work..
