**** the rear swaybar right in the ear. I was fighting the car all afternoon and couldn't put power down anywhere but in a straight line. The car was pushy in slow stuff, I took the bar off and the car was 15x's better.
I could actually use the gas pedal and the front end worked so much better - it tucked in off throttle and turned mid corner without any twitchiness whatsoever. Eff that noise - that shit ain't going back on my car.

2.2deg in the rear.
Current Setup is
Front
900lb springs
2.7deg camber
0 Toe
9deg of caster
1-3/16" 37.5" Hollow Front bar
Rear
700lb springs
2.2deg camber
.1 toe in per side (1/16" total)
Tire Pressure on the Dunlops was 38F/32R - same we ran on the RE-11's last year.
I think the lack of rear bar is allowing more load transfer onto the outside front instead of sending to the outside rear. This is hitting a sweet spot on the load vs grip plot of the tire.

Nick, what front bar are you using? Do you still have that custom 3 piece you made? (Found a thread in the sandbox) Nevermind... I see that is a yes. I've been wondering if that's too much front bar (based on what others are running) but apparently it's working for you.
I would agree with Nick on his observations regarding handling.
I am running the Comptech FSB at 200% of stock stiffness (middle hole) and the rear bar disconnected. No signs of pushing any where.
Other settings...
Front
750 lb springs
-2 deg camber
0 deg toe
about -6 deg caster
dunlops at 31 lb
Rear
600 lb springs
-2 deg camber
- 1/8 toe total
no rear bar
dunlops at 28 lb
I've also been shifting the shock tuning with more compression and less rebound. Moving both together appears to keep the critical damping.
Remember that comparing tire pressures can be way off due to gauge differences. I found that I was running the same pressures as someone else that told me numbers 5 psi higher with their cheapo gauge. The best way to compare is to use your own gauge on other tires. Of course that can't be done over the internet!
