Hey guys looking to get some feed back on what steels/ frictions work best in each clutch pack. Truck is going to be around 1200 wheel. Currently have c1 gpz, c2 gpz with kolene steels, need to replace c3 and c4. Seems like some people like the kolene in the c2 drum and some just like the normal steels? Also not sure for the c3, c4 pack what to run for frictions.last question I see to see mixed answers on is 1 shim or 2? Thanks for the help!
