To add to that, I still want someone to do A/B testing with an awesome link vs a PHB using the same roll center height.
I'll volunteer my car if there's somebody near Chicago that wants to actually do some instrumented testing in either Time Trial or race-group conditions... As mentioned, the roll center has to stay the same, though. It's not hard to swap a PHB, and from looking at it, not that hard to put on a Watts link either. I'm thinking start with the Watts, run a session, then pull it and swap in the pre-adjusted PHB (and stock brace), and re-run. No other changes. No spring rate, no damper adjustments, no tire pressure adjustements, just the rear lateral-location device. Highest peak-G and/or lap time wins? If no difference at all, then does the PHB win because it's cheaper and lighter? Assuming proper licensing and seat fitment (think skinny!), I'll even let the guy with the Watts drive both, and then we can compare data and notes to remove any potential (unintentional) bias. Can't get more fair than that. Two drivers, two different parts, no other changes, all on the same day at the same track with the same car. If there's a "ride quality" improvement to be found, I would bet it would show up on the Z-axis accelerometer.
