reffering to people who just state "stage x" yada. you sir, know what clutch material, hub design, and presure plate....it just so happens the company also names it in a stage for simplicity of begginners.

i dont have a link. i just called the companies. do a search on clutch masters and you'll find their page. or look in SCC for thier ad. its listed as the "stage 5" hahah.
