I would try to balance it out with tire pressures. I would start with 45 in the rear and 35 in the front and see where it's at. Of course, like you mentioned earlier, it's tough to get a car to handle well at Marina. You would think some of the local guys would have figured it out.

konis are full stiff rear. tried softening fronts, went too far started picking up inside rear. don' want to mess with alignment for one event, the car is good everywhere else. started at my normal 39f 37r ended up at 40f 36r...went wrong way? start at 38f 40r today and soften bar.
thnx

I was just looking for one of the other BS guys who already know my set up (like ULLLLLLLLLLOSE, who has fought this understeer problem on concrete...and was of no help ) to chime in with a quick fix, as I had a regional event today and discovered the issue yesterday. I figured that I needed a band aid fix, since I didn't really want to mess with the rear eccentrics and dial the car in for a surface which I (particularly now) have no interest in running on.
Anyhow, I did go to the softest setting on my modified stock bar and ran 39f/40r pressures to start. Big improvement, the car felt pretty darn good...unfortunately, the driver had problems, today. I don't think I even pax'ed top 10
Thanks for the help, though!

Seriously, I'm a little lost with the 18's and uber short sidewalls....

I get it
One thing which did become clear to me this weekend is that the RX8, as many of us have them set up, is pretty sensitive to rear tire pressure...much more so than the Z06 I ran, for example. Raising rear pressures by 4 psi made a significant difference in the handling, more than I would have expected, freeing up the back end a bunch. On the other hand, dropping rear pressures really didn't do anything. I'm not sure what this all means (maybe someone can take a shot at quantifying), but it is good information to have learned.
