What is your XDS setting David? Do you have VAQ?

I have a VAQ and have not touched any XDS settings.What is your XDS setting David? Do you have VAQ?
Following.
I’ve run mine in SCCA GS trim several times now, with the usual big rear bar, a 25mm Eibach for me. I’ve wondered out loud elsewhere if a front bar would be better, for keeping the front of the car flatter. It’s kind of a painful experiment to perform though with having to drop the subframe just to try it. GS only allows changing one bar.
If I ever do run the car seriously again, I’ll probably give it a shot. This years plan was to codrive an SSC FR-S, so that’s mostly what I’ve one.
I can do thatHas anyone been able to use something like this to determine the point at which further lowering puts the control arm on the wrong side of the camber curve? Would be interested to know exactly how much of a drop is too much, given the apparent poor design of the whiteline kit. I've seen people speculate an inch, but a lot of the coils I've seen are a minimum 30mm drop...
The larger change in front spring rate is due to the fact that ride frequency is heavily influenced by corner weights.While I won't argue with the math here (because it's clearly thorough), it feels opposite to the experiences we've been having so far. Given your experience upping rear springrate David, it would seem counter to your experience to almost double the front springrate and not expect it to push, while only upping the rear ~30%.
Again, it's hard to argue with the math though. If it takes that much front springrate to prevent roll / ending up in the undesirable part of the camber curve then it might work.
I know your calculations assume you have -2.1deg static camber, which will really drive up the need for stiffer springs / bars to reduce roll and prevent the car from going +camber. How do the spring values change when running -3 or -3.5deg? I'd be curious to see those, I anticipate they'd be a bit lower.
Can someone with an R measure the stock ride height from the middle of the forward lower arm bolt?I can do that
Zeroing out rear toe really helped with understeer, as well as a big RSB, when my car was in GS trim. My co-driver was consistently in top 3 pax in a region with 6 or 7 currect and former national champions, and I was consistently top 10.

2.875 to 6.25 (stock GTI ride height)Can you define min/max height?
