Mx5 Racing series - advice

[chimpnumber2]

Hi all,

Currently enjoy my mk2.5 but have an itch to scratch which is going racing.

After weighing up a few different classes I've decided to stick to the mx5.

So... There's a few classes but need advice on the pros and cons between each of them. Any thoughts?

Seems that most are mk1 1.6s so am on the look out! Like the idea of taking one and making it race legal.

Thanks

Chris
