Quick run update on mine. Went to my local track which is usually high bite clay, but with the heat and lack of humidity (SoCal Santa Ana Winds conditions), the track was pretty dry and had a layer of dust off the racing line which I drifted into a few more times then I normally would. First run out was pretty bad, car was very loose and had way too much steeering. Figured I would try running something closer to what Maifield was running at worlds since it seemed like It was close to those conditions. Made the changes, and the car was better with the tail end still being a bit too tail happy for a 4 wheel. Messed with shock oils, locations, but still ended up going with 2x1.7/32.5 middle hole arm, inner hole tower. if I tried to run any other configuration in the back, the shock became too stiff and springy. 1st day wasn't bad, mine you was only off my XB4 pace that has a center diff in it by .200 of a second consistent. I think another a brainstorming effort with me and a couple guys who do car setups I trust, and it will be just as good as the XB4 is right now. I'd like to add this as well, with the track being looser then normal, and the setup not being quite right, I did tag some pipe at very high speeds, and no breakage to speak of. Car is super durable.
