A weird thing i found though is that in some of Keven Hebert's most recent setup, he had 0.5mm more shimming in the front fwd mount than front rwd mount. That's similar to what i thought you suggested (which was my misunderstanding). now it really makes me wonder why he did that.
Arm sweep and anti-dive / anti-squat are two settings I've literally never tried, but wondered about.
I think I heard one of the fast local guys say he was using anti-dive to keep the front end up a bit more and maybe a little flatter on corner entry, and then some arm sweep to get back some of the steering he lost from the anti-dive.
I've always thought it was really curious that the Cyclone TC and TCX always have arm sweep in the stock setup, but most cars don't.
