Sizes: see table below
- Rear toe-in adds stability on power and under braking at a small cost in top speed (Tekno), and improves cornering stability on full-size cars (Wikipedia).
- EuroRC gives 1-4 deg rear toe-in for RC cars and says never to run rear toe-out because it causes snap oversteer.
- The file is a reference example built by Xem Studio from the numbers above (Reference 1/10 off-road: track 250 mm and 90 mm wheel+tyre (EFRA maxima); wheelbase illustrative.). Sizes the sources do not fix are illustrative; scale the example to your own vehicle.
