They allow you to upgrade your stock size to GT3 by retaining the use of your stock calipers (required spacers and longer caliper bolts are included in the kit)
Front rotors: 380x34mm (OE=340x34)
Rear rotors: 380x28mm (OE=330x28)
Essentially you would be upsize the rotor to same size as GT3, except we reduced the thickness in the rear by 2mm in order to fit the stock rear calipers (28mm max).
Front calipers are known to have asymmetrical legs (like 997 TT), no other brake supplier than RB was able to make this upgrade kit available.
However with our technical competency we were able to develop a pair of asymmetrical spacers for a 100% bolt-on installation with precise fitment.
2015 GTS w/PCCB, looking to retain PCCB calipers and uptake larger rotors
Can you confirm you have the same caliper as picture above (red calipers) with asymmetrical legs (slightly longer?) and the rotor sizes are 350mm Front and 350 Rear (similar to 997TT w/pccb).
If that's the case we can design a "slanted" spacer kit to oversize to 380mm which is the same CCM rotor kit we offer 991 GT3's standard iron brakes upgrading to CCM rotors.

The PCCB calipers on the GTS are "at least" different colors (yellows), not entirely sure if they also differ in dimension etc ... that would probably
require closer inspection of the part to determine that.
That's usually the case (997, 991), essentially they are the same caliper but the color.
Yellow caliper = pccb
Red caliper= iron (std) brake
Porsche varies the caliper leg length for different rotor size, and if the rotor thickness is different the caliper offset also got adjusted accordingly.

good to know - wasn't the case on the GT3 ... I'll take a look and see
i have 2013 c4s w/pdcc. will this affect the pdcc?
No PDCC (Dynamic Chassis Control) is a dynamic ARB/swaybar, there is no interaction between the braking system and h/w and this system, nor should any of the component modifications interact mechanically or otherwise.
