I have a TT02RR and running on black carpet and having major issues with understeer. I am running the short wheelbase, 2.5 rear hubs, spool in front, 7k diff fluid rear. 3 hole piston in shocks with 3k diff fluid (recommended by last years TCS Japan trip winner Vu), soft red springs. 3mm shim internal in shock and 2mm shim rear shock to limit droop. -2 degree camber all around, 4mm hex with 0 offset tires. The I have a crazy amount of understeer and literally have to run +5 degrees or more toe out in order for this thing to be somewhat competitive. Everyone else has a far less aggressive setup with toe out and for the most part the exact same setup but has so much steering and can carry so much speed through corners, while i have to brake in order to get this thing to steer. Has anyone run across this issue or any recommendations to fix this extreme understeer.
