Gray,

Yes, the pads signify different compounds.  Any Wilwood dealer should be able 
to crack the codes for you.

Or, surf to:

http://www.wilwood.com/products/brake_pads/polymatrix.html

This breaks down their available compounds.  I'm used to hearing about 
Wilwood pads by color, i.e. the "green" versus the "tan" pads.  Back when I 
bought my Wilwoods (1993), PPC normally issued their brake systems with 
"green" colored cold-stopper pads, which are good all-purpose pads but are 
noisy and dusty.  For people who are willing to compromise braking 
performance slightly in the name of civility, they offer the optional "tan" 
cold-stopper pad.

Their full-on A, B, C and D-series racing pads really aren't suitable for the 
street, but for your track car, might be the hot ticket if you drive it hard 
enough.
