Finally I found the best set up for the rally R50 Mini. I started with 2008 STI suspension which was toooooooooooooooo soft. Then I swapped to a set of 2013 STI suspension with 200miles for $300. On May 17/18 they worked a treat winning the 1600 class by 2 minutes. We won 10 0ut 12 stages!
See the motorsport section for the build. I would think this set up would work well on the street too
