alpha Racing Titanium Caliper Bolts...
Just to confuse matters completely I was really surprised how much the RCS master cylinder improved the S1000RR braking with stock pads and callipers at Portimao. The Brembo GP4-RX I fitted later have made a difference as well but not as much of a jump as changing the MC surprisingly.I changed my OEM calipers simply because Brembo Z04 front brake pads were significantly cheaper for the GP4-RX calipers. I never bothered changing brake lines or the master cylinder as it wasn't really required; especially when using Castrol SRF brake fluid.
I'm sure the new calipers will be absolutely fine on track once you change the OEM brake fluid and fit suitable race pads. As far as I'm aware BMW have done away with the ridiculous 4-pad per caliper design for 2019 which will mean that good brake pads will be significantly cheaper. I will probably still fit my GP4-RX calipers anyway, but that's only because I kept them when I sold my bike. The only question that remains is whether or not the 2019 S1000RR OEM brake lines will be compatible and allow a direct swap like the 2015-on model.
No idea why this keeps uploading sideway?!

The new one is a lot cheaper to feed pads...those Z04's are going to be much more affordable.
I admit they are somewhat excessive. They weigh a total of 96g, resulting in a rather pointless and minuscule weight saving of 88g... but they won't rust!
Just ordered mines yesterday. It?ll be my first bmw bike.

Brilliant. What spec did you order and when are you expected to have it delivered?
