I tried these out with Losi 27.5 wt with gold springs in the rear and they worked pretty well at my local track. I however prefer the 2 1.6 x 2 1.1 avid pistons with that same oil / spring combination.

i put my rb6 on setup stands and it looks like out of the box the rear toe is -3degrees, can anyone else confirm this?

And the only way to adjust the rear toe is with the optional aluminum rear hubs (no suspension holder inserts like the fs2 sp)?

Well, you could technically adjust it by using the RF and RF2 pivot blocks. I dont know what running a front RF2 and rear RF would leave you with though. We adjust the hubs, but the most I've run is .5

if you run the different rf blocks to adjust toe you will get excess outdrive wear and the car will be unpredictable on corner entry and exit due to the angle change where the bone and the outdrive meet. best bet is to use the hubs. IMHO

Can someone recommend a pinion gear size. I built the car box stock with stock slipper gear and will run 17.5 class on a medium size indoor clay track.

What motor?
How much end bell timing?
Blinky class?

Sorry about that I should have been more clear on that. I am using the 27.5 in the rear with gold springs and in the front I am using 5 hole with losi 35 wt and pink springs. Overall that setup has seemed to be very balanced for me on the current high speed setup my track is running right now.

we have a 17.5 open class so i will start with blinky but have the option for boost.

i will be using the orion pro esc and 17.5 motor combo. no motor timing mod.

thanks

Looking for a gearing for 13.5 Orion VST paired with Orion R10 Esc I run AE spurs.
On my 17.5 I ran 72/31

To get proper gearing for 17.5 on a medium size indoor clay track, I installed a Kimbrow brand 69T spur for the Associated B4(must also use Assoc. slipper pads), and around 32T - 34T pinion.
