I tried to measure everything out the other night on my Miata. I have been going pretty regularly this year trying to get used to the car before changing much.
Current parts list as purchased from previous owner.
Dunlop Direzza DZ101 205-50-15's (34-32 PSI)
Flying Miata front (hard) and rear (soft) sway bars (removed rear for one event)
Tokico HP Shocks and Springs
Front is 12" or a little lower
Rear is about 12.5"
Best I could measure with strings, levels and a dial caliper is as follows. Yes I adjusted for the 10mm difference in track and leveled the floor with shims under the tires.
LF = -1.71
RF = -1.91
LR = -1.95
RR = -1.87
Front = 0.071" or 0.25 degrees
Rear = 0.126" or 0.45 degrees
My general feelings driving the car are it understeers turning right and oversteers very slightly (perhaps just under power) turning left. I did not like removing the rear bar as it made the car seem vauge in the rear and understeered on corner entry and I felt like I was loosing a lot of time waiting on the car to turn. However the car is a bit skitterish in the rear under power with the bar attached. It is currently back on the car. This car simply does NOT like bumps.
I have another event this weekend and wondered if I should go to the trouble of changing things or just keep driving.
Main problems are low total grip in turns and transitions that race tires would really help. Oh yea and the driver....
