AutoX priorities:

-- This is achieved by REALLY high front spring rates, and a giant front sway
-- This also makes it so that under sustained cornering (sweepers), the car pushes like CRAZY, so that's why AutoX cars go deep, brake hard, and power out, rather than make a more rounded arc.

Track priorities:
- Sustained cornering speed, and being able to put power down at corner exits
-- This is achieved by getting a nice static balance.
-- Keep in mind that under power, you're unloading the front, and loading the rear.
-- Track prepped cars will sustain more raw cornering Gs, but not change direction and shift weight as quickly.


For example:

AutoX prepped FRS
- 14k/9k spring rates
- Blade type front sway, minimal rear sway

Track prepped FRS
- 10/12k spring rates
- Sways to fine tune balance.

Each car has its strengths and weaknesses. The AutoX car will likely slalom ~20% faster (raw mph), but the track prepped FRS will hold more speed on a skidpad (raw mph).

Also very true! Definitely application specific. Driver preference plays a roll too.
