i tried it out too, and it was a fun project, i got the setup real close to as fast as my rear motor configuration. but the rear motor car is just easier to go fast with at my track. i had a good 2 months with mm. someday i will try again

With the new hangers with adjustable inserts, will this allow us to now run in both narrow and wide configuration?

My point being, they're giving away the old ones bc the new ones can do both.

I believe it's only when you buy a new RB6.

I'd wait for the new hangers with adjustable inserts along with the new V2 hubs.

Am I correct in thinking that putting a thicker shim under the RR hanger I will be raising the roll center and reducing anti-squat, both of which will increase on-power rear traction allowing me to pull the trigger a little sooner exiting the corner?

Are you referring to this piece? If so I broke one too. This is the only piece I have broken. I'm leery of switching to aluminum because I don't want something else to break.

Ghea! As an added bonus, I have not bent another front hinge pin brace since switching to the Ghea piece as well.
