## Notes

- Ride height sets CG height and how much travel is available before bottoming. Too high feels floaty; too low bottoms out (EuroRC).
- Tekno: more front (or less rear) height moves weight rearward on power for stability; more rear (or less front) moves weight forward off power for more steering. Measure after dropping the car from about 6 in.
- Full-size aero cars care too: HPA recommends ~70 mm static splitter height because downforce lowers the car on track.

## Questions

**How do I adjust it?**

With spring preload collars; they change ride height, not spring rate (Tekno; EuroRC).
