What is a good overall chassis asphalt setup for 21.5
Miles, So Dialed's RC setup AI
For a Tamiya TT-02 Type-SRX with a 21.5 motor, use a 1/10 4WD touring-car asphalt baseline as your starting point. The motor class does not call for a different basic chassis setup, and I don’t have a specific 21.5T setup for this exact car.
- Ride height: 4.8 mm front, 5.2 mm rear
- Camber: -2° front and rear
- Toe: 1° front toe-out, 3° rear toe-in
- Caster: 4° front; 2–3° rear
- Kick-up and anti-squat: 0°
- Shock rebound: 0%
These settings are intended to give a balanced baseline on asphalt: the front toe-out helps turn-in, while rear toe-in supports stability through corners and on the straight. The ride-height split keeps the rear slightly higher than the front. The TT-02 Type-SRX’s kit setup already has 3° rear toe-in, which matches this baseline.
Check ride height with the car fully assembled and ready to run. If the track is especially low-grip, this high-grip-oriented camber and toe baseline may feel edgy; change one setting at a time and judge the result. If it pushes mid-corner, try a small increase in front toe-out; if the rear feels loose, add rear stability before changing several settings at once.
