You can order police pads for the front which are a different compound and will take more abuse than the Volvo standard pad for the 280mm or 302mm front brakes.

I was under the impression that with front pads (standard Volvo) there is only one for the 15 inch (280mm) and 16 inch (302mm) as both use the same calipers. The bigger brakes just use bigger discs, longer hoses and different carriers to space the calipers further out.
The 17 inch kit was totally different with different calipers, floating discs etc and has unique pads.
The 15/16/17 inch reference was a Volvo reference related to the wheel size required to clear said brakes.

Clearly aftermarket manufacturers may make numerous compounds but for Volvo oem AFAIK there are only 2 for the normal front brakes (standard and plod). I have no experience with the 17 inch kit but would very much like a set!
