different brake for different use. the GTR kit is not a good choice for 430.
Brembo GTR kit is great for track use while PCCB is great for the road/street use. the GTR kit is designed mainly for racing not for street use. it is extremely noisy & the brake is too good for street tire can handle. it's hard to imagine if there's any brake system bites harder than PCCB but the GTR kit certainly be the one. here's some weight info between the GTR kit & PCCB:
F PCCB rotor: 12.2 lbs
F PCCB caliper (with pads): 12.6 lbs
Total: 24.8 lbs
R PCCB rotor: 12.2 lbs
R PCCB caliper (WP): 8.2 lbs
Total: 20.4 lbs
F GTR rotor: 19.8 lbs
F GTR caliper (WP): 7.2 lbs (W/OP): 5.2 lbs
Total: 27.0 lbs
R GTR rotor: 13.4 lbs
R GTR caliper (WP): 7.0 lbs (W/OP): 5.2 lbs
Total: 20.4 lbs
some pics:
notice the quick release design of the pad for racing (that causes pads to move around therefore it's noisy. also see the pad design for the minimum heat transfer)
