The Mini GP3 handling setup is the important part of this build.

The F56 GP3 is a very capable and enjoyable car, but it also has characteristics that need proper attention. With a powerful front wheel drive layout, short wheelbase, torque steer and lift off oversteer, it can feel quite nervous if the setup is not right.

On this car, we have focused on making the chassis work properly before anything else. That means AST 5100 coilovers, adjustable top mounts, camber adjustment, anti roll bar preload, a slight track width adjustment, a different tyre choice and our own performance geometry setup.

We have also included a track use performance package with an intercooler upgrade, intake res delete, panel filter and ECU calibration.

The aim is not to remove the GP3 character. It is to keep what makes the car exciting, while making it more composed, more usable and more confidence inspiring on the road.

That is what a proper setup should do.
