1. Engine mixture control buttons. Higher mixture - higher power but also higher fuel consumption
2. Push 2 Pass control buttons. Activates by click and deactivates on next click or on braking.
3. These are a very important keys to control your car. Brake bias keys is mostly for road courses and street races - helps you to control braking of your car. ARB and wedge is very important for oval races. Stiffening the front ARB will increase the car understeering, makes the car more stable in high speed turns. Increasing the rear ARB will make rear of the car rotate more. Wedge is an ultimate parameter which helps you control the car in different ocassions e.g. if you're in front of the pack you need more wedge, if you're following other cars you can put less wedge. Cool thing about wedge is that it's changing the car height so you can see how the car moves up and down while you standing still and changing the wedge
4. Good to have those buttons assigned. Pit request and pit limeter are necessary for every type of race we have in our championship.
