This is only a review on the track on a semi modded Base V4.
Sears Point (Sonoma Raceway) is not as hard on the brakes as Thunderhill is, as the terminal speeds are lower.
The new GPFAX pads in short felt very similar to the stock pads but they did have a bit more bite and power, especially as the session and laps got longer and faster.
In the stock pads, I felt there was a point that they started to fade a bit, as well as the lever travel got a bit longer.
I have smaller hands, so the lever position and movement become critical for me to get the best times and feel most confident on the track.
I liked and will continue to use the GPFAX pads. I am happy with the results and will continue to test them out.
With the extra power, I did not have to pull the lever quite as hard to get the same braking results, so lever travel was slightly reduced.
It did not effect the lever travel much, so I see a new master cylinder in my future, So the lever can stay in the ideal zone.
