Figured I'd post some feedback about track pads from this past season. I also posted this in the
Track Brake Pads Thread, but want to include it here in case people don't follow that thread...
I run the following brake setup:
Stoptech/Centric High Carbon Blank Rotors
G-LOC GS-1 Compound Pads (Street)
G-LOC R8 Compound Pads (Track)
Tyrolsport Brake Bushing Kit
Removed dust shields
Motul RBF600 Fluid
I can't say enough good things about the G-Loc pads. The R8 compound performed flawlessly over a pretty grueling 2-day track event at VIR earlier this month. There are two high speed (130+mph) braking zones in each lap, with many lighter braking zones in between, and I didn't notice any pad fade during any 30 minute sessions. Very little wear during that event, and they are easy on the rotors. These pads even do well at low temps on the street, but the noise they generate is pretty intense. Because of that, I run the GS-1 compound on the street, which is compatible with the R8 on the same rotors. The GS-1 pads have a very similar coefficient of friction as the R8 in cold temps (maybe even slightly higher) and are quite easy to modulate. I really enjoy running them daily. So far they are quiet with less dust than the OEM or Stoptech Street pads I've ran in the past.
A few notes:
Bedding procedure is critical for the R8 compound pads. I tried to bed them in on the street, but wasn't able to get enough heat in them. They did properly bed in during my first session on track, which caused me to lose half a session so I could let them cool. Because of this, I would recommend getting them pre-bed from G-LOC. This is to bring the pad up to temperature to properly off-gas the pad material.
I've reached the limits of Motul RBF600 and find that I need to bleed my brakes at the end of each track day (meaning I'm boiling the fluid). I will need to upgrade next season to either RBF660 or Castrol SRF.
Can't wait for next season!! Schedule was just released.
