Scala: Open wheel II
GB3
GB3 testing: a faster British single-seater championship one step above F4 and GB4.

What it is
GB3 is a British single-seater championship that sits above F4 and GB4. The cars are quicker, with more downforce and more to learn about setup, so testing matters even more.
Who it suits
Drivers with a season or more of F4, GB4 or similar behind them who are building towards international single-seaters.
Testing with Karat
A GB3 test with Karat includes the car, tyres, an engineer and a mechanic, with data and video afterwards. Many drivers book back-to-back days or a pre-season programme; request a quote for one.
A chi è adatta
Drivers with a season or more of F4 or GB4 behind them.
