Here is the setup I used at the TITC 2019. Car was good enough for the win. Just ran out of luck with backmarkers. TITC was a highspeed, high bite asphalt track with a lot of bumps.

I used the wide front (as 195mm was allowed) Tried many things. Like geardiff, spool, different bodies, ride heights, narrow front. But this was the best, and most consistens.
