To the open wheel racing – there are NSR F1 cars and the soon to be released Policar modern F1 cars. I could see us running the NSR cars. They have been out for a while, parts are available and they come in enough colors and liveries to work for everyone. Spec Series
BRM Trans Am cars. These are basically overgrown Revoslot cars that are fun to drive and perform well. – Spec Series
BRM/TTS mini 1/24 scale cars – these include the Alfas, Ford Escorts, Mini’s, Opels and soon to have a Autobianchi A112 Abarth coming in the next few months. Spec Series
Scalextric or Fly BMW E30 touring car series with Shapeways 3D chassis – Semi-Spec Series
Rally Track – Targa 1969-1973 – Open Series
Rally Track – Group B unlimited. Any car in Group B from 1983-1986 with unlimited modifications. Open Series
The difference between Spec Series and Open Series is the amount of modifications that can be made to the car. Spec Series is just that – a spec car with stock or limited modifications that can be performed. An Open Series allows for more (not unlimited) amount of changes to improve the performance of the car. These series allow the builder to be creative and discover new ways to improve a cars performance. These series can be slightly more expensive due to the expense in additional high-performance parts.
