SS1 – immediate traction in cool low grip track conditions. Ideal for hill climb, time trial or vintage applications.
S2 – extreme levels of traction to deliver ultra-high performance in the open competition environment.
M – Ā heat tolerance & consistency in performance over longer race stints, and provide more usable heat cycles.
MH – highest level ofĀ heat and abrasion tolerance for a high level of consistent high level of grip and performance.
