Start with the kit setup, Rear Motor, 37F and 32R oil, narrow rear suspension hangers. It's a great place to start, tweak from there.

I have the vts in my rb6, fits nicely with the avid top shaft, and it's better bracuse it has more contact patch than the triad does.

Take the motor out, and take a picture of the hole/motor guard area where the motor would sit.
Maybe this pic will help...

That's the wrong hanger.
The rear outer hanger is a triangle shape. Here's the metal version

That's the mid motor rr2 block. The holes are clearance holes for the screw to pass thru to the mid motor bulkhead. I can't believe the screws didn't fall out.

Yep, that is the RR suspension hanger for the mid motor setup. Break out the other 4 (two pairs of two) and line up the narrow pair, and the wide pair, and run one of those pairs (wide for more steering, narrow for less). The piece you have mounted there, toss in your MM pile of parts.

Thanks for all the help, If anybody has the plastic susp. holders from the build for rear motor and have not used them, let me know i may be interested.
When I bought the buggy he did not include the other MM parts or in this case proper RM parts

I have to admit the more I run the car the more I am impressed. I have been playing with pistons and oils and have settled on a setup for my current layout that seems very easy to drive fast in mod. I did also switch to all Orion gear and all I can say is its so smooth it's deceiving. I sort of wish more of the K drivers would pop in and share info on what the team has discovered works or doesn't work. Would go a long way in helping us all develop.
