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

(J - why builders want rollers? any specific reason(s) to this?)
They advertise "superior thrust control", which makes no sense because the shaft uses the IMS rear flange as a rear thrust bearing, and even the factory IMS bearing uses the center bolt to limit forward thrust.

We have pulled a lot of OEM bearings, and not once have seen evidence of excessive thrust loading.
