Is there any advantage of the new aluminum suspension holders over the old ones? I have the old ones?

More adjustability.

With the new hangers you can run narrow and wide plus more.

I'm glad I read this. just switched to mid motor but i was worried about getting the weight to transition rearward quickly. 2 mm spacer? what are the negative effects?

Don't really need any but the weakest links would be the steering link and RF hanger I think.

Didnt the front brace get a running update?

Everything else is for a bit of extra adjust ability or just bling.

I think Exotek makes their own version. Not sure if it's the same or not.

Did you just break the front one? If so, the other "RF2" hanger that comes on the tree has the same dimensions but just less material I believe. I measured it the other day.

The front brace is a running change.
It also looks like the chassis has a few more holes for battery placement.

I have been running the RB6 since its release, i go threw front bumpers front arm holder and front arms.

Upgrades i would recommend rear hubs , suspension hangers and steering link.
