Yeah, money isn't really an issue at the moment, it's just a matter of time saving it. Car isn't going to be tracked seriously though, so I doubt that i'd get value out of a big brake kit. Get the impression that the R34ones are a little overpriced (cause R34, cause brembo), the 33 ones look like the ticket.
Edit: they're the same size anyway, didn't realise that.
