My BMW 335i

I am yet to see anyone ever regret a quaife or helical.

...other than drifting/skidpan duties.

I kind of want to upgrade my factory helical with a Quaife (but really it's not ultimately that different, and is a MASSIVE UNDERTAKING), that's how good the hype is about them, that I want to try them 'just to see'

Maybe also really stiffly sprung track cars. Get the inside wheel up in a corner and all the fun stops.

Also me sometimes (rarely) when I have to stand on the brake to convince the diff to drive the wheel that is still on the ground when I'm trying to diagonally get over severe driveway entrance, etc.

Sounds like a job for an over engineered solution... Two little levers in the cabin, each controlling their own brake caliper to a specific rear wheel... Now it's like you have a hydraulic drive vehicle when you get into the "tripod" situations.

Yeah, I am super excited for this.

This is a big issue for me without the diff. I just have zero drive from the passenger side when drivers side has no traction. Bec's parents place has a crazy steep driveway with odd camber and I have never been able to get up. My bro-in-law's 130i with an (unknown brand) LSD gets up fine as does their dad's Hiace. My car stays at the bottom.

We have other odd camber roads around here as we're elevated a bit and if it's raining I can get totally stuck around some hairpins.

You mean you will regret it for drifting duties? I don't quite follow.

A proper clutch/plate type mechanical diff with quite a lot of pre-load and high locking % is better for drifting. Much more consistent in its behaviour. A helical can be annoyingly vague and inconsistent in how it responds under the sorts of abuse found in drifting.

Oh and some up-and-comings;

New rear drivers wheel bearing. I'll do that this weekend while the diff is out. The car is already up and the d/c axles and missing exhaust will help with space. This is the last bearing for me to do and I've been dragging my feet on it.

I also have some new EBC blue stuff pads for the car and some new brake fluid. I haven't ever flushed the fluid in this car and looking forward to it. I have 600 degree fluid to put in. Not exactly "race fluid" but better than the typical stuff I have been using.

Woot! My diff is done! I just need to finish doing a wheel bearing while the exhaust and shaft is out of the way, pick it up and hopefully put it in next weekend!

And then vids of skids all the way up the in-laws driveway!
