I have the comptech adjustable.

I set it to the softest setting with 205 front, 245 rear R-compound tires and experienced very slight understeer. I was also running stiffer front springs with respect to the rear ones.

Later, I switched to 225 front, 245 rear and set the bar to 2nd to the stiffest setting. The car ran great.

Saner bar on softest setting with 225/245 RA1's and 225/255 Kumho MX street tires.

I might stiffen the bar setting for auto x on concrete, but currently it is stiff enough for my usage. When I change my suspension set up and go with higher spring rates (current 340/380), I will probably try to go with a matched set of non-adjustable bars or go back to the stock front bar.

I picked option 3 because I only installed the bar this spring. I only have one auto-x, and one track day on since that time. At this point, I am still trying to dial in tire pressures on my Kumho Victoracers (225/50 F and 245/45 R). Once I get tire pressures dialed in, then I'll start playing with the bar - just haven't yet.

Triple-H

Stock bar, only do a few autox events a year, do at least 8 track days 3 of which are open track and I drive about 5 hours. I run Toyo RA-1s- 205/55-16 and 245/45-16 with a modified alignment. Can handles great, backend is tame and predictable on the track and can be easily pushed out while autoxing.

Comptech "beta" bar, hollow slightly larger (heavier) than current production model. Seems to work well with my 225-40-17/ 255-45-17 Kumho MX setup for AutoX. A little heavy but OK for street with 215-40-17 245-45-17 Pilot Sport. I may increase front camber beyond UK spec when I complete my spring swap to front bias.

vroom

Saner bar - #2 hole. Started with softest setting (#1 hole) but moved to mid setting on the advice of someone better than I. Khumo Mx Street tires ASA rims, 225 x 50 x 17 Fr, 255 x 45 (50 - i fergit) x 17 R, no excessive understeer, can move rear around at will even with 255's. Standard BS Solo II setup of khumo Victoracer 225 fr, 245 r on 16's (OEM wheels).

Just (i mean just) added Konis - this I'm starting to like, full stiff Rebound front, full soft rear. Saner will probably stay at the 2nd hole.

Have not tracked the S2000 yet - might have to bite the bullet and do a PDA event at Pocono (not a big fan of either), though next years car improvement budget might be a roll bar so that I can get to Lime Rock.
