I ran Gloc R12s f/r on my gt350 for 2 seasons and was very happy with the crisp initial bite, power and had zero fade. Used that setup at NCM for TT nats last year to a 2nd place finish.
I tried the same on my GT500, which while faster and heavier, has much bigger brakes up front. The OEM pads have good power, bit initial bite and pedal feel was a bit soft, and I could fade them after a few hot laps, especially when they got worn down a bit.
Switch to the R12s and some AP R4 fluid - pedal feel and bite did not really change much, and I was able to fade the fronts after just a couple of laps. Not confidence inspiring. I had to go back to oem pads to get some safety margin back.
For those that have done the R12-R16 switch did it solve some of those issues?
