I am considering building a Ka race car to compete in the Castle Combe saloon car chapionship, the question is which year car to use ? Do I use the earlier car with the crossflow engine or the later car ( I know nothing of the engine used in the later cars )?

Are there as many tuning options for the 70bhp engine as the 60bhp engine?

Which coilover suspension is best used for track work? Are they camber adjustable or do you have to fit adjustable top mounts?

Thanks in advance Dave
