Performance oriented brake pad options

I recently learned that new pads which are DOT approved have to have a friction code listed on them! Which is very interesting, it potentially allows an easy option for adjusting front rear bias if you have 4 wheel disk.

Not really. The rating system is very coarse and doesn't address subtleties of braking response. For those manufacturers participating it was supposed to provide a level of information for the technician that they shoe or pad was in the same ballpark as the originals. For extreme example one might think an FF rated lining is pretty good, but if its real grabby on initial contact then that would be a poor choice on a shoe (drum brake).

If the brakes on the vehicle are decently sized or oversize, then one can get a wider range of use out of a lining before it gets hot. In other words a street oriented pad will have a better chance of holding up in a road course type event. The one track type event I participated in didn't even get the factory 10" disks, 10x1.75" drums hot. In part thats because the way the event was run. My point is you may be able to start with something good for 'cold' and as you go along, switch the fronts, if/when you start to ge tthe fronts (or fronts and rear) above their operating temperature range.

Porterfield will put their linings on pretty much any pad or shoe you want. They also will arc the shoes. My Barracuda currently has their R4S on the D11 pads and 311 shoes. Its a good all round lining. It works OK even dead cold. While it may not be shown on line, they had the D11 pads and 311 shoes in stock. D11 pads are also used by the 'other pony car'. ;)

A few people on FABO used EBC Red D11 and wrote favorably about them. My recollection is the Green is not appropriate to our cars with steadily deacreasing bite as it gets hot, and Yellow is for hotter track use but may be harder on the disks.
