Looks great!!! Do you feel any braking improvement after installation?
BTW, I can't find that would fit slk32.

Because Rears are fine for now. I needed new pads and rotors for front so I replaced with crossdrilled.

I notices it takes somewhat longer like 1/50th of a second for initial bite when I start to use brakes at high speeds like 100MPH - may be I making it up and it's the same, or may be it's due to smaller initial contact area on porterfield pads - they have triangular shape - as they get worn contact area gets bigger - probably for initial burnin. No significant difference, but I was very happy with SLK brakes to start with - only went with drilled rotors for looks.

Interesting - even main brembo catalog doesn't list applications for SLK32 Breco Brake System - Aftermarket 2007

You probably can get drilled rotors from C32.

The rear brakes do not work anywhere near as hard as the front brakes do in stopping a car. The effort supplied by the front brakes can vary from 70% to 90% of the braking force while the rears only 30% to as little as 10%.
If you look at your brakes you will see the rear discs are MUCH smaller in diameter, have less brake surface, and use much smaller pads. Obviously the pistons are quite a bit smaller, but that may not be as easy to see.

Do the drilled discs make any more noise than plain ones?? I had some EBC Turbo Groove discs on a previous car which made a noticable whirr sound every time i braked which can be off putting.

None. Very quiet. But keep in mind - i got Brembo, results may vary with different brands.

So - I locked the wheels today.

Was driving in traffic around 40MPH and was paying attention to a guy on a side and if he is going to try to squeeze in front of me - suddenly realized the Honda in front of me was slowing down. So i hit the brakes really hard and BAS kicked in. Wheels locked almost instantly - car followed the straight line, nothing dangerous. After I did let go of brake pedal - BAS still was applying brakes with about half of pressure for half a second. So I went 40MPH to about 5MPH in instant - brakes worked perfectly !

Guy in a wan behind me probably needs a new underwear.

I need to replace my discs soon because they are warped and quite worn (probably original after 90k miles) and was looking for Brembo ones. Anyone know where I can get them for a 320 in the UK??
