Luke. I can swap them on my car but they are is a ****ty position and I can alps re pin them too. It's not that hard. Also I was chilling with Stephen (ia performance) and we were discussing this cam gear ****. He said that the gears are the same him and Dave from ralisport use the usdm one on jdm engines. Anyways. He thinks the extra advance is in the actual cam. But that is kind of off cause I have usdm Sti cams in my car running 40+ degrees of Avcs. So I think it could also be the passages to the ovc valves as well. They might flow better and can get more timing.
