Damper

Damper adjustment is the biggest challenge. A damper controls the rate at which the spring is loaded/unloaded (sprung in/sprung out) and it is 4-way adjustable.
Adjustment options:
Fast shock controls spring-in speed over bumps etc.
Fast recoil controls deflection speed over bumps etc.
Slow shock controls deflection speed over chassis pitch and roll.
Slow recoil controls deflection speed with chassis pitch and roll.

While the springs determine how far the vehicle tilts, the dampers determine the speed at which it tilts.
They are used to fine tune the handling. A high value indicates a slow damper, a low value indicates a fast damper, i.e. a fast damper allows high spring in or spring out speeds.

Principles:
- Front damper as low (soft) as possible for best front grip.
- Rear damper as high (hard) as possible for good high speed cornering stability
- slow setting controls bounce weight (chassis pitch and roll) when weight is shifted
- fast setting controls unsprung weight (tyres, wheels, brakes) over bumps
- soft dampers good grip
- hard dampers good high-speed cornering stability

- Fast bump: soft setting Car does not bump as much, but it becomes more sluggish
- slow bump: soft setting car becomes more docile, but again more sluggish
- with soft springs, dampers that are too hard cause the spring not to be fully loaded and they are therefore neutralised.

- the settings for shock and rebound should not be too far apart, as then the spring is loaded very slowly, for example, but can be very fast when unloaded, which can make the car undriveable.
- The fast recoil damping should always be 1-3 parts higher than the shock damping.
- The harder the springs, the harder the recoil damping should be.
