With this setup I was able to run a constant time between 26.765 and 26.950 on SuperSpeedway. The Setup still needs a little tweaking but still runs fantastic.
You don't need to have MT on since you will never jump below 6th gear, unless you prefer to use it.
Brake Balance isn't much of a concern since you will not have to use your brakes at all.
Just keep low to the solid white line the whole way around the track to maximize your times.
*I will update the Gear Ratios and possibly more of the setup as I have time to tweak them.*
