I am familiar with over steer and under steer, what the heck is overshoot? Bill Schmidt 88 Red devil Kawi
>>> "Chuck Voboril" <[EMAIL PROTECTED]> 10/02/06 9:45 AM >>> I ran the tall rears in conjunction with 18 fronts for about 5 years. I found that the 19's were narrower but since they were taller they had the same grip. Hoosier told me they were designed that way. However, if I ran them enough, especially on concrete for about 6 events in really hot weather (112+F), the tall rears stretched and got wider and taller, especially wider. Thru a slalom, the mixed sizes never felt as good, the shorter rears made the car easier to control and a little faster thru the shortest spaced nastiest slaloms. A little more overshoot in the back had to be compensated for with hand input with the tall rears. I never ran the tall tires on all 4 wheels, but my experience with other cars was that the overshoot in the front would make the car have a little less net rear overshoot in turning. The downside is that then the car would be a litttle squishy and less responsive to steering input overall then. I always thought that running a little negative camber in the rear would have helped the tall tire grip also. Other people have also. The most recent person to design and build a rear end on a F500 that could put sizeable amounts of neg camber in with uprights that could assume an angle to the main axle cut the whole rear off his car and started over again. (rulebook heartburn). Actually, it was done about 1990 also and then more recently in about 2004. Neither car continued production with that "feature", as far as I know.
