Search for SL63 possibilities

[Lemmand]

Salutations everyone,
I'm about to witness an R231 SL63 that was made before the 2013 FL. It would mean a lot to me if someone could verify that the rear limited-slip differential is an option (471).
The code wording strangely suggests a locking front diff?!

Differential lock for the AMG front axle, acceleration skid control (ASR), and mechanical locking disc

What is the option code for the performance pack, and how can I tell whether it has the extra power? It appears to have the LSD but no power boost, which is strange.

Yours truly.

Like with other PPs, I'm assuming it's option P30. Is that right?

[Messand]

The performance pack is indicated by the red callipers, if I remember correctly.

I could be selling mine very soon; are you just seeking a PP?

[Lemmand]

After looking at many AMGs with painted callipers, I can say with confidence that it is not dependable.
Without exception, a PP is my top pick, barring a later MY with normal diff.
