Im still going back and forth trying to decide if I need to be $500 poorer taking the plunge on a set of G-loc for my new STR 40 BBK this year, or just take a chance on the Stoptech sport pads they came with. I am running front and rear brake ducts ss lines and RBF660. Nothing would disappoint me more then to invest in the one track day of $350 plus a few hundred more for hotel/weekend expense this year to have the brakes boil over again and lose half the day to no brake pedal. Previous set up was stock with ss lines, front brake ducts RBF600 and HP+ pads.
The Stoptech sport pads have noticeable more bite then the OEM pads. Seem to be somewhere between OEM and HP+ as far as the characteristics. But im hard on brakes at track/late breaker and my S2k is pretty much stock full street weight with a lot of tire, so with the addition of the rear ducts and BBK this year im still not sure if that will be enough to protect my braking with sport pads. Anyone have experience aggressively tracking with these? Id be interested to know where the sport pads reside on the effective heat spectrum scale.
Its just one of those things, where funds are limited, so have to be very systematic about upgrades and cant just drop it all all at once and unfortunately race pads are a significant cost and hard to swallow for one track event a year (pays for my track day/weekend-or own pads) but try and address each weak link as they show there face and as funds allow. Taken me many many years to get this car situated, but I still like to track it in the interim for fun and test/tuning reasons of course. I was looking at getting G-loc 16/12's. Running 275/315 stagger on NT05, but will Stoptech pads hang in their?? The track I run, there is 3 significant brake zones on 2.5 mile course. 125mph to 65ish. 110 to 35 and 90 to 30.

My guess is you run into brake fade for sure with that setup. I found the yellows to fade much less than the Stoptech, but my yellows started falling apart after a hard weekend. I plan to run R10/R8 all the time and have $340 in the set.

My issues in past have been loss of pedal/fluid boil over. The HP+ pads actually would still bite and engage ABS, but after the 3rd or 4th session typically id be 1" off the floor to get there and it just became too dangerous to continue the day, so I could never run a full lapping day. That prompted the BBK and rear ducting this year. And move from RBF600 to 660.

My experience with the Stoptech sports from my time in the miata is they can handle heat, up to 1300F but they took a lot of pedal effort. I had tried Carbotech, HP+, and Stoptech sport and the stoptech were my least favorite to track with. On the S2K I bit the bullet and went w/G-Loc due to my preference of the Carbotech but hearing that G-Loc was the improved version.

Thanks for the feedback. Do you run the yellows with oem calipers or BBK? Any Ducting?

Shame, I have been running DTC60s on my E46 as track pads for a while. I was hoping to carry that forward on the S2000 since I can put together this setup for $230, which I can't seem to match with anything else I've come across.
