Chaning things up for this winter. 25 lbs stiffer on each front spring, stiffer front sway, will have a rear sway again.
Setup:
350 front left
325 front right
700 rear left
628 rear right
Ground Control 7 gauge race front sway
CSL rear sway with some adjustable end links I made myself
Puts me at 1.89hz front, 2.07hz rear, so 1.1 bounce ratio (10% flat ride).
Depending on where I set the sway adjustment I can set the front roll couple to be pretty much anywhere in the 70-80% range-- going to start it in the middle and dial it in by taste.
Front roll stiffness is ~double stock (over/under depending on where I end up setting the sway), rear roll stiffness is ~50% more than stock.
I really enjoyed using flat ride in 2019, but the rear end feels slightly off without a sway. I'm hopeful this new setup will be bang on perfect.
If it is, next winter I'll have the Ohlins rebuilt/revalved for my specific corner weights/spring rates. They're coming due for a rebuild anyway, and my corner weights are pretty finalized (not much significant weight left to take off the car).
