I know, makes you really wonder if the kit got balanced in that Finland backshop before each installations lolll That should have taken care of the harmonics at best.

Was just sayin RPM, often the easiest decision benchmark when CAE data is out of reach. Old formulas. Tons of engineer calculators available online that will let anyone know how much you'll be able to rev up that little sport car during those spirit drives (roller vs balls, etc). Not a taboo thing

MicroPoly - Maximum RPM Calculator

(J - why builders want rollers? any specific reason(s) to this?)
