511 rear hubs? FAO Pidge!

[simoncrabb]

Just built my 511, and out of the box, with the kit rear hubs the ball cups catch on the wheels.

The instructions state to put the outer balls in front of the hubs. But do it that way and they catch. So I swapped them to the rear, and put the inner mounts on the rear too.

Now, looking at the TRF team cars (see pics at http://www.oople.com/rc/photos/euros2009/day4/), they are running a totally different rear hub with 3 vertical ball positions, so the balls go upwards, rather than outwards.

What part is that? Is it available? It makes sense, as then roll centre height can be adjust at both the inner and outer end. And presumably fixes the kit problem I encountered.
