I’ve been chasing front end grip from day one on track.
Put on better tires and added a 034 RSB. Less understeer but still easy to lose front end grip. Lack of front end feel and responsiveness at turn in.
Fast forward fall last year. Re-valved my Ohlins for 8k/12k springs and dialed in -3.4 front camber and some front toe out. The front end was much more responsive.
I have been following this thread closely. Auto-X and Track/HPDE are to very different disciplines. Auto-X set-ups being more extreme, but overall because it is the same car it is directionally correct.
I have been against stiffer swaybars. Preferring to use spring rate to support the car and to control roll. The stiffer the bar, the less independent your suspension becomes. I’m starting to come round and thinking that a stiffer front sway may be in my future and potentially going back to a stock rear sway.
I’ve under-estimated the impact of camber loss in roll, to front end grip. Dialing in -3.4 of static camber has helped. Most probably need a little more. Need to get my tire pyrometer out and re-check tire temps. I’m also thinking that I need to adjust my driving style and reduce my usage of apex curbs which pitches the car further over.
I’m not bound by your Auto-X rules, so have had much more flexibility on suspension mods. The Verkline front LCA will give all sorts of adjustments. Given that I can dial in all sorts of front camber. I most probably will need to cap that at -3.8 for the track.
David, based on 450lb/672lb and an 034 RSB set on the softer of the two settings, what size front swaybar would you recommend?
I’m curious about going back to my stock RSB for my next event at VIR. It’s an easy swop on rhino ramps.
Also, I have more headroom to go to stiffer springs without needing a re-valve.
As far as what you should do, I don't have enough data to know what front/rear roll couple we should shoot for right now. I'll post up later today what I think the stock vs my current roll couple is and maybe we can make some observations.
Until I have better (more rebound or DA) shocks, I may have to go back to last years spring setup in order to keep the car a daily driver that I don't hate.
However, I think having more front camber, higher front tire pressure, a stiff front bar, and rear toe-out will keep the car happy-ish.
