im ordering a mcloed rst twin disk and im going to resurface my flywheel. i have the stock steel flywheel laying around and also the one thats mated to the spec stage 3 thats in the car. my question is which one would you guys have resurfaced and put in with the RST. also i was wondering if i go with the 26 spline input shaft about how much extra labor do you think that will add on at a shop? i really want to do it when i do the clutch and i think i can pony up the $350 for the part but if its going to be an extra 2-3 hours of install time idk if i can do it yet. let me know what u guy think. wanna order asap
