Most recent setup from doing droop tuning at Fastlane tonight. I found that 37.5 made my car feel really good in the front over the weekend, so today I watered the track, and found that it was better than 35 when the track was tacky, but the car still felt too twitchy. I noticed that nobody on the team has really ever ran 37.5 oil in the front, so I decided it must be front droop that was to blame. That it was. I ended up back at 20mm, really liked it, then went back to 35wt and the steering came back and was predictable and not twitchy. I also tried more and less rear droop and found that I preferred 26.75 in rear. Believe it or not, the difference between 26.5 and 26.75 in the rear was pretty apparent. It wasn't make or break, but you could tell, and one was definitely better than the other at our track.

I also have been doing some tire testing and returned to running ions instead of electron fronts because the ions are far more stable and predictable due to having denser tread at the edges and the nice stability rib on the sides.

I have given up completely on closed cell front foams on 2wd. They just don't fill up the tires or last. They fill up the tires when the tires are new, but after a few club races of traction compound, the tires expand enough that even new closed cell foam doesn't fill them up completely and they slide around. I've gone back to 2/3 - 3/4 of a rear open cell foam cut down and profiled by hand. Slightly softer than a closed cell front, but the entire tire fills up firm. Seriously feels so much better on the track and makes re-foaming fronts a breeze. They also last about the same as a closed cell for me. I've compared AKA and blue PL.
