As someone who started last year in sprinting (in a modified class) I can heartily recommend it.
I would stay with class 1 (unmodified)
I would buy:
a good new helmet
a second hand fireproof suit( if you like sprinting buy a new one)
proper boots (you can use them to drive even if you give up sprinting)
A proper roll bar(safety devices)
A good seat. Sparco Rev good if you are slimmmish!
then do 4 or 5 events and see if you need anything else and if you like sprinting.
This will save you money in the long term.
