Sizes: see table below
- Toe is the angle of each wheel to the car's centreline; toe-in points the front of the wheel inward (Wikipedia).
- Front toe-in gives straight-line stability and an easier car but slower turn-in; toe-out gives more corner-entry steering but less stability under acceleration (Tekno; Wikipedia).
- Extra toe-in slightly increases tyre wear because the tyres run with a small slip angle when straight (Wikipedia).
- The file is a reference example built by Xem Studio from the numbers above (Reference 1/10 touring car: wheelbase 260 mm (AARCMCC ISTC 250-270), track 190 mm (EFRA width without body), 50 mm = EFRA rim limit.). Sizes the sources do not fix are illustrative; scale the example to your own vehicle.
