I currently have the S197 4-piston Brembos I used to run the PowerStop Track Day pads and loved them for the initial bite and overall stopping power - and value. However I felt that I was outgrowing them and switched to new rotors with G-LOC R12 pads. While their modulation seems a bit better than the PowerStops, they do not have that strong initial bite and do not seem to stop as well as the PowerStop Track Day pads - especially at the end of a 135-140mph straight at Pocono. I'm thinking that I probably should have gone with the R16s instead. Castrol SRF flushed with SRF with the new pads and rotors.
Looking ahead, I have a set of S550 GT PP Brembo calipers that I will install as soon as I get my second set of Apex wheels - for next season. Since the pads are significantly bigger than the S197 4-piston Brembos, are the pad recommendations equivalent or is there a 1 to 2 level difference? For example, will an R12 on S550 PP Brembos make the car stop like an R16 (or even R18) on S197 4-piston Brembos? Or is the initial bite/modulation the same with an R12 (or whatever compound) on either caliper with the main difference being heat dissipation and reduced fade.
With brake cooling in all cases.
While the example of above uses G-LOC/CarboTech compound designations, the same question applies for all manufacturers with multiple track pad compounds.
Thanks

P.S. In my opinion, the G-LOC GS-1 street pads are not as dusty but not nearly as good stopping as the PowerStop Z26 street pads.
