    Anyone have any experience with RE-71 tire pressures on Gen3 Cooper S in D Street? The car w. 6 spd auto scaled in rather heavy, at 2746 lbs (3/8 tank -no driver).

    The other sites where a lot of people autocross Focus, etc seem to be way up there with pressures in some cases, but not all. Some have settled on 36 front and 38 rear with the 205/50/16.

    Trying to prepare for my first event. Going to be running RE-71 205/50/16 on 14.8 lb OZ 16x7 rims. Originally ordered BFG Rival S 215/45/16, but Tire rack wouldn't sell them to me since the tire load rating was under the Gen3's door plate rating for max GAWR.

    Oddly, the RE71R 205/50/16 tread width is just as wide or wider as the 215/45/16 BFG as well as wider marked widths, but lower aspect ratio RE-71's.

    How about suspension settings for the GEN3 in D-street?
    Slight toe out front and zero rear?

    Thanks for any help!
