I dont run any expo on the steering and really cant get the rear to step out unless I'm out of the line and in the dust. In the groove, man, it's just insane how good it is.
The track I was running at was dry, hard packed, and fairly smooth in the groove. Blockades, Impacts, Cubez, and Catapults all worked pretty well. The Blockades were better over a larger range of conditions but the Catapults were the best for the most part. The Impacts had the worst wear characteristics and the Cubez had the narrowest window for working well (soft compound but needed 80°+ to work really well).
From Mo's setup, I dropped 50cst front and rear. I tried the setup without the LRC pivot block (was waiting on the postman) and it was fairly loose but once install, it totally transformed the setup and really locked the car in. It is a very aggressive setup and begs to be driven the same way, you can really blast into corners and just throw it in without worrying about traction rolls or big slides. I tried 5/5/5 and 5/5/4 and actually like 5/5/5 for that track a little better (5/5/4 would diff out occasionally when I was really on the power mid corner through the higher speed infield turns). If you arent already, 5/5/4 may help you out of bit however. Oh, I'm running a bit more droop than Mo's setup as well but I wouldnt expect that to be a major contributor to your condition unless they're drastically different. I cant remember Mo's ride height off the top of my head but I ended up at 27/27 I think.
