I'm running a TT02 with a pile of Hop-Ups. Aluminum suspension, oil shocks, aluminum steering linkage, driveshaft, universal axles, uprights, etc.
3.9 FDR (60t spur, 40t pinion).
21.5 turn Speed Passion VTA class.
2.5 degree rear toe-in.
1.0 (or a little less) degree front toe-out.
0.5 degree front negative camber.
100,000 weight front diff oil, 2000 rear.

Cornering issues.
Good turn initiation, followed by savage under-steer.

Suggestions?
General advice on setup welcome.
