Theres actually a set of "Ultra Wide Universals" from 3Racing and they're supposedly able to hit 55 degrees. The hybrid setup involves using MST axles which fit perfectly with the MST knuckles if you're running them for the KPI mod.
I've been waiting for a while for TQ to get the 13T and 22T alloy pullies, and I am considering just replacing all the 13T with the 12T and changing the 22T to 23T, which would raise the CS ratio to a little over 2.4 . Not sure how that would be like though. The other option would be to get the 21T which would result in a 2.22 CS ratio. Maybe I'll just get both and see
