<center><img src="http://www.mnsolutions.net/Audi/padoverhang.jpg"></center><p>Just installed the ECS Stage 2 v2 kit consisting of a Boxster caliper and 332 mm, 2 piece rotor.
Noticed that the pads do not come in complete contact with the rotor but rather "hang" off the trailing edge by about 2 mm!!
I'm using the car on the track so I'm a little concerned about this. Has anyone else noticed this? Any problems associated with it? Seems like a less than perfect design to me!

I have had no issues with it...what I do is take the pads out and sandpaper the "lip" down......
It's fairly common......if you have any additional questions talk to Jason @ ECS...he's been very helpful.
Talked to another Stage III owner who said the lip caused the pads to vibrate terribly.
As far as being "fairly common" this is the first time I've ever seen somthing like this. Basically looks like they just decided to stick the largest possible rotor in there. Not very sound design IMHO.
I'm seriously thinking about returning the kit.

else chime in and say regarding this kit?

Mill 1-2mm from the carrier bracket pedestal to allow the caliper to sit 1-2mm closer to the hub.
Within reason, don't worry if you remover too much metal; you can always adjust it back out with washers. I set my Alcon calipers so that the rotor is recessed in just enough to catch a finger nail on the edge of the caliper. During braking, the rotor expands to slightly outside the edge of the caliper, but no lip ever develops.
I believe this pic shows the ECS S2 carrier bracket.

As for milling the bracket, to do so would reduce the number of threads/material that the caliper bolts would have to grip. Probably not a big deal, but I'd feel better about milling the caliper at the mounting point.
All entirely doable, but I can't believe that after spending $1600, I still have to do all this work to "make it right". Never mind the 3 week wait and then having the wrong hats sent to me.
It's all more than a little ridiculous.

It doesn't look like the caliper can move at all, and I wouldn't risk milling and weakening the caliper.
An alternative kludge: Mill the excess pad material from the pads before you install them.
I have a similar problem with the inside radius of some pads for my Alcon setup. Pagid and SBS pads fit fine, but I need to mill the backing plate of Ferodo pads flush with the pad compound to avoid having the backing plate hit the rotor hat. Cobalt Friction pads require extensive milling to fit. All four pads are the pad specified for my Alcon TA-6 caliper.

I ended up keeping the keep and installing it instead of sending it back. They wanted 15-20% for a restocking fee.

same experience......that's all I know....I love the Stage III BBK so I'm keeping mine and working the situation out...
I'm keeping it and will "make it work".
Having said that, I'm thinking about selling the Boxster calipers that came with the kit plus the HP+ pads. Both are new and unused. Email me if interested.

Well I have just imported the Stage 3 BBK for my S4 and have just discovered this whilst installing the kit.
Thinking that I had incorrectly installed the kit I now find that this looks like a poor design. There should be no pad overhang. This will cause a step in the pad and will weaken the integrity of the pad. Also of course the size of the mating surfaces is a prime constituent of brake torque.
Quite frankly it's a bleeding disgrace if ECS think that it's acceptable to take $2000 off me for this and leave me with a fundamentally floored performance product. They advertise their kit as 'having thought of everything'. I hope they have a good explanation.
