Anyone play around with a 12.5 high-RPM rotor in a TC (17.5 stock)? I know the magnet strength is a little lower.... maybe too low to be running in a 1380g car? I haven't personally checked a high-RPM rotor for numbers.
I have 2 very strong purples that feel good, and a third one that's a bit older and a little weaker (never cooked). Could I get the same effect in terms of gearing/RPM with the weaker purple? I find myself liking the car with more timing and shorter gearing given our typical layout.
Congrats to everyone with success at Snowbirds!
