I had an opportunity to ride in a BRZ equipped with the AP racing sprint kit and wow

I had some weak street pads on my Wilwoods but the AP system had significantly more stopping force. Part of it could have been the passenger seat but I was very impressed. I'm swapping out my pads this weekend and will get another track day here in a few weeks which will give me a better apples to apples comparison.

Show up to ITR Expo and we can compare. I know you can't for other reasons though

I wish I could. Although Mid-Ohio isn't too tough on the brakes (if they leave the chicane in). Plus I'll have my innovate supercharger on tomorrow night

At some point you need to visit my home course, our cars were made for it:

I was at Slummit a few weeks ago.

I will never run an event there due to history with them from 2004 (yeah I hold grudges when it almost destroys my event) but I don't mind visiting.

What organization are you running with? I'll be at VIR with TrackDaze Aug. 26 - 27 and again in Nov 11 - 12.
@Dave-ROR

Just curious, but what happened at Summit? I was there last weekend and had a good time.

Or build one.

We were planning our annual event there (ITR Expo) and they were beyond difficult to deal with and eventually pulled the date because they screwed up on Shen when they were building it. Instead of having us run one of the other courses, they were just complete jackasses. All good though, they lost the money, BeaveRun took us back with very little notice and we sold out quickly so it all ended well.. but it could have been bad. I avoid dealing with tracks that I've had issues with in the past (I mean running/organizing events there, not going to events at said location) simply because I don't have the free time and energy to expend on unresponsive people who I am paying 5 figures to for a service.

That was one I was looking at. (August)

Sweet, I'll see you there.

Back to my earlier post, is just removing the pad retention bolt all you are supposed to do to swap pads? Like I said, it can be difficult to get the pads in and out, especially when there is still a lot of pad material.

These are helpful

I usually remove the outside pad first, then open the bleeder, then push those pistons back in with two old pads (pads sitting horizontal, one per piston for leverage). Then install replacement pad. Then move to the inside, compress pistons again, close bleeder, install replacement pad.

You can just use a screwdriver between the rotor and pad that's already there as well but I don't use that method.

Otherwise the edge of the disc against which you are levering can damage the pad. Also, the edges of the pads and gouge or damage the pistons...which is not good. Also, you have to be careful doing this with race pads. Some become brittle after a number of heat cycles. If you use them as a lever, drop them on the ground, etc. you can easily crack the pad material.

You may just want to fashion a small, smooth block of wood for this purpose. It will be easier on your pistons, your discs, etc., and you won't have to worry about breaking, scraping, or gouging anything. I had a little pine block that I used for years. There are a couple of caliper spreaders on the market (the Girodisc one comes to mind), but they are expensive and large/difficult to store and transport.

As Dave said...do one side at a time, or you'll be playing piston tennis....back and forth, and back and forth.

I'm getting tons of PM's...if you guys have any questions about what's right for you, call me 704-824-six zero three zero 8-5pm ET. I don't bite, and it's far easier and faster than sending 46 messages back and forth as I gather details!

Fwiw the ds2500 are silent on my oem caliper/rotor even with a light bed in.

I'm still eyeing a sprint system but want matching rotors >_>
