I was at the Octane Academy Thursday, I took my car out so it can be seen and the head of the race shop, the one with dozens of race Mustangs, wanted to check the car out, he drove it and loved it.
I asked him what they are doing for brakes on the FiST as the pads did not sound aggressive like they did on the FoST.
Stock pads and rotors, I did not ask about fluid but that is pretty much a standard for any track use, upgrade it.
Any issues? None, even when it was over 100 degrees
How often do you change pads? Every 2 months or so
Tires, BFG Comp 2 on stock wheels.
Longest session, right after somebody else got out of the car, 25 minutes, so 50 minutes or so of going all out on track with one fairly quick stop.
I found the car to be very easy to drive all out, brake late, no fade, not R comp tires which would allow later braking but I was going in very deep and pretty aggressive on the brakes but it was in the 60's that day.
Once you go past stock power, stickier tires, that is where the most issues seem to come up...so a BBK or at least cooling ducts and the best pads and fluids may be needed.
The 11.75" BBK can be sourced to fit under some 15" wheels, the prototype caliper mounts will need an adjustment to bring the caliper in just a bit closer to the center as mine are a bit to close to the rotors, I am going to send the info in on Monday to get the correction dialed in.
Many pads to choose from, different grade rotors available but the GT's will work the best and last the longest, kit price is very very affordable and maintenance time, which sucks if at the track, especially the cost to be there and miss any time lapping, etc....overall this can be less expensive that stock brakes and a great deal better.
