Re-use stock flywheel
I re-used mine after cleaning is up 0.10". It MUST be re-surfaced, there is no other way to re-use unless you want to do another clutch change in 1,000 miles. Also, I would suggest a 3+. The 3+ is full faced where as the 3 is a 6 puck. I have now used both & strongly suggest the 3+ over the 3 even if your power level doesn't require it. The re-surfacing of my flwheel was $50.
Also, you must have the pressure plate & flywheel assembly balanced. This will cost another $50, but, needs to be done regardless of whether or not a re-surface flywheel or new flywheel is used. Good-luck
