Caliper studs + G-Loc Pads
After my track days in March and my road trip, brakes were hurting. I was starting to hear tons of noise and definitely didn't have enough pad life left to complete my upcoming weekend at The Ridge.
After talking in Optimum Performance, I decided to test out a set of street and track pads from them. I went with their street pads GS-1s and then R16s (front) and R12s (rear) for the track. I went with this over the R12s because I wanted a more aggressive initial bite and Optimum was fairly sure I wouldn't overload the stock MPSS tires (more on that later).
Because I anticipate swapping pads out, I bought a set of studs and sleeves from Epiphany to make front pad changes easier. Here's are all the tools I used during my stud install and pad swap.
1. Lift car and remove the tires. I did fronts and then rears.
2. After removing the tires, remove the stud bolts holding the front calipers in.
3. Then support the calipers so they don't hang. I used this high-tech setup.
4. Make sure to clean the threads out before mounting your studs. Mine were pretty dirty. I used a wire brush and compressed air.
5. This is a good time to clean the rest of the dirt off. Here are what mine looked like after cleaning.
6. After everything was clean, I installed the studs. Make sure to follow the Caliperfexion instructions on using threadlocker and torque. They're very clear and concise.
7.Slide the calipers over your newly installed studs and attach the sleeves if you have them.
8. If your pads are worn, you'll need to push the pistons back because your new pads will have more material. Two ways of doing this...bleeding your brakes and compressing them with clamps. I chose to bleed because I wanted to check my fluid and I could do it by hand.
9. Here's the difference after pushing the pistons back.
10. Next up is prepping the rotor. While best practice is to just buy new rotors, these pads were pre-bedded and the instructions from Optimum say that sanding the Rotors is fine. So I sanded the rotors down a bit, cleaned with brake cleaner and re-installed.
11. To fight brake squeal, I added grease to the back of the pads. This step is pretty unecessary. If you get your brakes hot enough, it just cooks the grease anyways.
12. All done!
I'll give more notes on the pad performance during a track update post, but so far I am happy. The GS1s feel very good on the street (very similar to OEM) and their dust is very minimal. Very street friendly pad. The R16s and R12s are absolutely killer. I went for a bed-in run before my track day and was able to overpower my stock tires once they warmed up if I mashed the brakes. However, the initial bite was absolutely killer (very sensitive) and with some self-control, they are great.
Regarding the studs, everyone else has pretty much said all you need to hear. The hardware is beautifully machined and they are great for changing pads. Well done, Epiphany!
