I have a pair of these gears along with a set of hks cams, and I was wondering since there is no degree markings on the adj part, how would one know how many degrees adv/ret they moved the cam?
Think about it this way - considering the increased frustration, the lack of repeatability, the likely missing I/E/X markings, and the propensity for those gears to slip after you've set them, I'm SURE that the few dollars you saved will make it all worthwhile in the end!!!
