I'm getting so much contradicting information as I search all over online.

I have a set of Calipers:

- Unpainted
- 996.351.425
- 996.351.426
- Brembo


Can someone tell me if they are from a BASE Boxster? Or Boxster S? Are they Fronts or Rears? Year range they would have come from?

I WOULD REALLY APPRECIATE ANY HELP. BTW I searched on this site with the part number and the search would come up empty. Pelican came up with a result but it had extra numbers after my part number. As you can see in the pics, I only have those numbers.

 

I don't know about the part numbers but the black calipers tell you that it's from a base Boxster (or 911). Whether front or rear would depend on the caliper/pad size (other than through part #'s). Do you have the entire set? If so, the larger ones go on the front.

My guess is that these are either from a base 996 or a base 987. Hopefully someone who can identify them by part numbers will chime in.

 

Alright, I've done some snooping and it appears that your calipers are for a 996 C2 fronts (left and right). Or 986.2 Boxster S fronts, but then they should be painted red, not black. Hope this helps.

 

^ Thank you for your help. Appreciate it! I was so confused because of the missing part numbers.

I went to the Greenwich Porsche dealer with the calipers in hand. The parts guy who usually helps me knows a ton and he was originally stumped too. He hadn't seen a set of calipers in stock without the extra two numbers. He looked up 986, 986S, 996C2, 996C4, 996C2S, 997C2. He was nice enough to spend a little time going through the Porsche catalog but every number had an -01, -11, -22, or some variation. I needed the caliper hardware so it made it even more difficult. Luckily there was one damper plate lodged in there. He pulled it off and saw it was 36/40. His hunch is that these are 996 C2 Front Calipers. He said Boxster S always came with painted calipers since it was a upgraded model. They would be either Red, Silver or at least Black. Boxster S and 996C2 had the same front calipers so they should qualify as either. I ordered a full hardware rebuild kit so that will be the moment of truth. I ordered:
99635108802 x4
99635195901
95135191701 x2
95135191700 x2
99907340201 x4

 

You're welcome. Good luck!
