If you are using hexes yes. You will have to remove some depth from the hex area on the front wheels since the front hex on the rb6 is much thinner.

After closer reviewing manual you are totally correct, Thank You !

Has anyone ever heard of a sensor cable with a right angled plug? I'm thinking something like those right angled SATA cables.

Here is my current setup if anybody is interested. Still a work in progress of course, so don't expect it to stay this way for long I update this exact PDF online with all my changes, so the setup will be different depending on what week you look at it. This is for a medium to medium high traction indoor clay track.

Are you using the factory metal bushings inside of the aluminum exotek rack?

I put mine on last night.
Yes.
Get some M4 0,1mm spacers too, as recommended. Eliminates wobble. Be sure to get as thin as possible, thicker will cause binding.

Be sure to use a shorter ball end on your rear shocks with the RB5 arms. I first had the long ones on and the spring adjuster was backed out all the way. I use the short ball end. Have not tried the medium.
