OK, the JE skirt coating is nice - I've been planning out a built motor for my DD WRX for a while and kind of waffling between rolling the dice on how long 2618 pistons with more clearance will last, or trying to make one of the few 4032 options work. Problem solved!

Additionally... I wonder how the Weismann overrunning clutch system works in practice compared to more "modern" actively controlled systems. Obviously there's more scope for having an active diff do things to control dynamics but there's something to be said for simplicity, and it's not like Weismann is some fly by night company with no experience in this stuff.

Dan, the overrunning clutch looks interesting. In theory in a straight line it's a 100% rear, 0% front split until the rear does any kind of slipping and then it allows up to 100% transfer up front depending on available traction at the rear. in a turn you'll need quite a bit of slip before the front can get power. essentially it would need to slip enough to where the rear is tracking the same turn radius as the front.

I'd certainly like to give it a try, i bet it is fun to drive on low traction surfaces.

A lot of Weismann's stuff is based off the same overrunning clutch concept. Used for this, it's certainly a mechanically elegant way to do things. I just wonder... like, Weismann lockers were useful in racing back in the day, but got superseded (on asphalt at least) by good clutch pack limited slips in part because you can tune ramps and preload and everything to affect handling in useful ways. I'm wondering how well the same concept holds up vs all of the electronically controlled options when it's turned longitudinally instead of laterally.
