I had my first track day at Brands using the new brakes (SP1 MC and calipers with brembo racing pads). It is far better than I just had the SP1 MC and standard calipers.
One thing I've noticed is that the brake lever, if you squeeze it hard comes to the bar. I was surprised and expected there to be air in the system. Not true, it means more feel. I didn't realise this... super.
However, now I'm looking for new Fireblade forks that will fit (hopefully with only a little modification). My forks have already been upgraded, ohlin internals etc, and having it set up by actiforce, he recommended either an overhaul or Fireblade forks as they have more adjustment. I'll put a post wanted section..
