We'll have Porterfield pads for our FiST soon! Porterfield is very open to making new pads for nearly any application. They're a friendly group, easy to work with, and local! In the past I've had new pads made based strictly on description and an outline sketch (sent by FAX or email). Those pads worked pretty well, but I recall having some minor fitment issues at least once. Since I wasn't in a super hurry, I decided to mail them my used pads. Hopefully this will result in a higher quality product for us. They can make either the R4 (race) or R4S (street), but I asked for R4, first. I'll share an update just as soon as I get the pads! At this point, I think this may be later next week.
