E46 M3: Which pads for trackday?

[mpit]

As per the title - I've just picked up an M3 and 'm after some pads that'll see me through a few trackdays.

I had DS2500s in my Clio 182 and I found they would start to fade if pushed hard for a few laps in a row, so I'm guessing I want something far more substantial for something as weighty as an M3.

Any recommendations?

I keep hearing reports that the RS29s squeal like mad when hot, though.

The car is primarily a road car - I can't deal with ridiculous squealing again.

They didn't squeal at all after that?

I did the same set of things chasing the squeal in my R26 Brembos, nothing I did would make it go away

How dusty are they? Is there an alternative that is a little less extreme?

I suppose one option would be to put pads in just for the track day, but I think that would be even more annoying, and I'd prefer the car felt the same all the time.

Did you upgrade the rear pads at the same time?
