I read through everything I could about FiST brake upgrades, but wanted to share my situation in hopes of clarifying my options. I attended a race school this past weekend in my bone stock 2014 FiST and was on track for 7 sessions progressing in time from 15-35 minutes and progressing equally in intensity. 20 minutes into the last session my pedal went soft so I babied it through 2 easy laps and it felt 60% firmer but still soft, so I pulled into the hot pits and let the car cool for 10 minutes. Back on track for a few more laps and the brakes never felt right again, a bit soft, not grabbing as hard, mild vibration in the first 1/2 of brake application. For the last week of street driving the pedal has felt the same, slightly softer, not grabbing as hard, mild vibration in the first 1/2 of brake application. I checked the pads and there is plenty of material left, the rotors feel a bit scarred but not that visibly bad. Here are what i think my options are because I plan on doing at least 2 more track days and a few autox sessions this summer. I plan on flushing with race brake fluid regardless. 1. Replace front rotors with OEM and be more mindful during my future track sessions. 2. Replace front rotors with Stoptech slotted and a set of new OEM pads and go nuts on the track. 3. Machine rotors (although I don't think this is a good idea) Any advice on what is has likely happened would be appreciated, I know I am not the first to face this conundrum.
