Wrench is a mechanical simulator in which we can mount our own racing cars, in great detail. We will start as a simple mechanic, a junior assistant of a great racing team. At first, and as befits our category, we'll start changing tyres and rims, but in no time we'll move up a level and we'll be able to start dealing with more serious things.

We will gain levels of mechanics depending on each car component we drive, as well as race results. Increases in mechanical level increase our role in the team and will make us responsible for a greater part of the mechanical systems of each car. Maintain an extensive library of parts and assemblies including: engine lower end, cylinder head, front and rear suspension, and brake systems.

Diagnose mechanical problems with a variety of tools including the parts log book and driver symptom reports.
