Negotiate Suppliers

This allows you to choose a supplier for your cars engine, chassis and tyres. Each of these have their own attributes which will help your cars to perform better.
The more the better simply, but of course you will pay for quality - unless you build your own.

Please Note: If you get a supply of chassis in from a chassis supplier, you will not be able to use your own chassis. You can continue to develop it but chassis usage will default to the suppliers chassis.

Fuel Suppliers

The amount of performance a fuel supplier can bring is really down to the engine you already have. A good fuel supplier can give a boost to performance of around 20%, however it will also have a detrimental effect to the reliability of your engines. As the power output goes up so too the reliability of the engine will go down.
