Brakes: Replacement Dust Boot?

Only downside is your bank account will have $81.99 less than it did before. They're great. I'll try to snap some pics of my dust boots - look absolutely brand new.

Is that the FR-S specific Wilwood kit?
I see 4 piston caliper... unless those are the rear calipers?

Keep in mind that lowering brake temps will not only lessen brake fade and improve brake performance, but it also extends the life of the pads and rotors.

It's a WRX kit modified with a different mounting bracket to fit.

The rotors are .5" bigger diameter than stock, but they are actually thinner than the stock rotors at .81"

There was a pretty heated (no pun intended) debate about this kit on another subforum where the Wilwood guys were saying they'd fail on track, but I'm not sure fried dust boots can be considered a failure: http://www.ft86club.com/forums/showthread.php?t=32594

They definitely look to be struggling with heat on track and it makes sense that a thinner rotor would have less thermal capacity. The stock dust boots have met the same demise at these Wilwoods at the hands of @Dave-ROR at Sebring. He actually got the stock front brakes so hot that the rotors started delaminating material off them. See here: http://www.ft86club.com/forums/showp...&postcount=156

Here were my Wilwood BP-30 pads after about 1K street miles (some spirited driving), properly bedded, and 2 sessions at VIR:



The heat might explain the molten lava that ruined my wheels.

Something tells me this is why your pedal was going soft

Perhaps race pads = too much heat for fluid and street pads = too much heat for pad

I'm going to try those titanium shims from hard brakes. My next track day and last one for the year (maybe) is at Summit Point - Shenandoah which doesn't have the same stress on the brakes that VIR does. I'm also carrying more speed (with supercharger) and moving my braking zones deeper as I gain more skill. I didn't expect getting this into the track at this point or I would have gotten a more solid brake kit. The kit works great under heavy street use, autocross, etc. Perhaps it reaches it's limit under extreme track conditions.

KNS updated their site and put the titanium shims back up:
