So after my last track day at Thunderhill, I baked my rotors and pads. Mainly becuase I had the wrong pads, Mintex Red Box. These pads were only a month old when I got to the track. Look at them now. Yea I know, my fault. Having these on kinda ruined my day at the track...

As you can see I needed new rotors and pads badly

The heat created baked the paint on my calipers, looks like crap now. Should have repainted them black. Next time.

This is what the rotors looked like after one track day with Mintex Red Box pads, which are NOT for the track!

I think I will start to use seperate street and track pads from now on.

I put ATE slotted rotors and Pagid Blue pads on as replacement. Got them from germanautoparts.com Great people there.

On a scale of 1-10 for rotor/pad replacement, give it a 4. Very easy to do, at least for the fronts where you dont need that brake tool.

LOL!! Nice job on the old rotors!!

Pads are not the only thing that need to be upgraded for track use. Many rotors are also designed for street or AutoX use.

I was running brand new Raybestos pads in the rear, because during my pre-track inspection, I realized I was down to 20% left on the rear OEM pads... So, I figured more "cheap" pad was better than much less OEM pad, and slapped a set of Raybestos from Schucks on (I didn't have time to order a set with only one week before the track event, and no time to do the work.)

my rears looked like yours at the end of the day, I even got flagged off the track for sparks coming from the rear wheels.

This past weekend, I put on the ECS two piece A8 rotor kit up front, and OEM S4 rear brakes in the back, with Mintex C-Tech front and Hawk HPS in the rear. This should be ok. The S4 rears are vented, so much better cooling capacity. Track time next weekend. yeaaaah!

Ouch to the old pads/rotors. Yes, Red Box are not meant for track :-)

did you have to do some grinding per the tech article to get the s4 brakes to fit?

The Pagid Blues are fairly agressive pads, IIRC. It's a bit of a trade off running agressive pads on OEM-size 1 piece rotors, the risk of warpage/excessive wear is high.

I found that the Mintex C-Tech Compound (Mintex BLUE box, not the Red box) on the OEM rotors is a pretty good compromise for track days. The pad will hold fairly well, but won't be so hot that the stock rotor will warp. For first timers w/ out brake upgrades, going with this pad limits the initial $$ outlay, and helps to avoid replacing parts at significant cost after the day is done. (Like velo had to)

ditto...porsche calipers if you are going to track alot...can change pads w/o removing caliper

The S4 rears are a simple bolt on, but you need to get the calipers, carriers, rotors and the dust shields.

The tech article uses A8 rotors @ 269x20mm The actual S4 rotors are 256x22.

The front's are completely different, which has been discussed before, that the A4/S4 are not interchangeable.

There isn't much info available about the S4 rears being a direct bolt on. I think WYSIWYG did it as well, but I'm not sure.

If you're going hybrid like the tech article, there is evidently some modification, but if you can find a complete rear S4 setup from a junkyard, you're set, no modification required.
