frivolous or not it would still be something to look into for a heavily tracked car, if not for anything other than preventing any trouble. It's not like it costs an enormous amount or anything, more than i'd spend if I never went to the track though.

Well you need to ask yourself this question, what is a fill or drain plug anyway? Well simply put, they are two threaded devices that inhibit the flow of diff. fluid from the diff. to the exterior of the vehicle. Now in all reality two lines to a cooler will in essence do the same exact thing, thread in and keep the fluid inside the differential. Pop the lower line off to drain the fluid, put it back on, pop the upper line off to add the fluid, put it back on.
Most differentials don't even have drain plugs, you pop the cover itself off to drain the fluid. Then you replace the cover and put the new fluid in through a fill hole in the top of the differential case, not the rear cover.

I believe most import (Japanese & European) cars with independent rear-axles have drain plugs.

No it's not Turbo'd
You would "Think" drift and "Race" teams would benefit the most with the differential locking and unlocking in the turnsm, yet from what I've read they either go Kaaz, or some sort of custum rear cradle / diff setup... so it seems like it might do something but not enough over stock for the street people to care, and not enough for the race people to not consider an aftermarket setup due to the weakness of the stock torsen...

And Jimlab's Cobra Diff setup are the only ones I'm aware of... I would think they'd work with a stock (Non Ls1) FD as well... I've never had the Privelage to Look at racecar diff setup except for Rotary Power's Drifter... and I remeber them just reinforcing the welds, and adding some solid mounts instead of rubber....

Bah! First off, solid diff mounts make the diff weaker. Allow me to explain. If you have rubber or urethane insulating there is something to allow for a certain amount of deflection for the torsional forces applied to the differential. Henceforth the only benefit of a solid mounted diff is more power application to the ground due to these "absorbers" of torsional force being eliminated. Also, differentials with these lacks of drain plugs are domestic only and a terrible design due to the fact that every time you want to change fluids you have to re seal your diff. The greddy unit is only for added fluid capacity due to most "serious" drift and track cars utilizing clutch type diff's. More fluid means that it takes longer to heat soak and with all of the added cooling fins makes the higher fluid capacity cool off faster. It is an unnecessary upgrade for a street car or a car with the stock differential. Thank you, come again.

Bumpin this up.
I had the Greddy diff cover installed on my diff, and I'm going to be ordering oil tomorrow. IIRC the stock diff setup takes 1.2 liters; anybody have any idea what the Greddy diff cover turns that number into?

Btw, I meant 1.2 quarts, not liters. I have to stop reading all of the overseas threads...

KAAZ 1.5 way with a 4.44 final drive and the Greddy diff cover.
No sir, the diff is literally being put together right now down at JPR Imports in southern NJ(side note: James at JPR is a SUPER cool dude so far). I blew my stock diff at Rotaryfest and had to leave the car there. The new setup(minus the r+p) will have 0 miles on it and needs to be broken in. I'm using the KAAZ fluid for break-in for 500 miles, then swapping to Amsoil. I'll be there with both my Cayenne and FD(guess I have to pay entrance for 2 cars :-( ).
So how many quarts should I ideally put in?
Also, Rich doesn't believe the car will be ready for the track until its been to IRP(jk jk ;-) ).
