Here we utilize axle diameters that will provide a bit of both Options #1 & #2 (Forward Bite & Throttle Turn), using smaller diameters overall with a slight split between left & right side axle diameters. What this means is that BMS has already worked out the geometry issues in the front so you can hit the ground running. 0000024076 00000 n Lower pressure on the left side will provide a lateral force that counters the centrifugal force that is trying to take the car up to the wall. 0000030792 00000 n HS: We could maintain the previous setup as the track begins to smooth out, but it will keep a considerable amount of grip. 0000043596 00000 n This option is our maximum recommended offset between the left & right side axle diameters to allow for "on throttle" turn like that of adding tire stagger. 0000044412 00000 n Change the RF spring to a 750-pound spring and the RR to a 175-pound spring. 0000065960 00000 n 0000083854 00000 n brp9706. 0000071813 00000 n 0000045332 00000 n Dry slick, a condition in which the track has lost considerable moisture and is now very dry and slick with little grip: 0.7 to 0.9 g's (The cars are now very slow in getting into and through the turns, and traction under power is very low.
