Sounds like if a Jeep could handle the torque, I dont see why are 7's wouldnt be able too.
I have heard of this method before, but have never seen it done before.
Ive also seen things on ebay, I think they were called Phanton grip, but I cant find them now that I want too. They claim that you put this piece in there and locks them together for a cheap conversion to LSD.

thats the problem with the gsl rear end i need to rebuild it errr... know of a good place to get parts for the rear end....like the oversized clutch disc........

I would do it to my 7 if I didn't already have a GSL.
I've got both front and rear locked on my '80 Toyota p/u
It would chirp around the corners a bit, but with the tiny little tires on our cars I don't see it being too big of an issue.
Do IT! especially if its just temporary while you rebuild a GSL rear end

Phony grip diffs are a joke. They're weak and prone to break. MANY people have broken them. Don't lock up as well as a good GSL clutch style LSD which is a better solution all around.
My LSD was built with >1 oversized clutch disc. It's breakaway torque is OVER 175 ft/lbs. I stopped checking it @ 175 cause I didn't want to strip a wheel stud. I think the shop I got it from may have replaced ALL the discs with oversized ones cause that mother still hops a tad and groans making tight turns in the paddock and I put not one but TWO bottles of Ford LSD additive in there to loosen it up.
I can feel the LSD slip just as I go into a corner. It's REAL tight. Great for track but overkill for street. 1 oversized disc is fine for street.

I am getting my differential rebuilt prety soon, and I was wondering if there was a way to get it tighter than stock specs.
Yes. Replace all discs except 1 with new stockers. Put one oversized disc in there. It'll tighten it up to approx 120ft/lbs breakaway compared to 90 stock.
Is this something I can ask about at the shop and they will know
If they build race diffs for mazda's they should know otherwise.....
, or can I just buy the parts myself and take them in?
Yes. Much preferred method.
Id love to have it tight like that but I really dont know much about modifying the rear end. Since you think they may have replaced all the clutch discs with the oversize ones, is this something that could be done without hurting anything?
You don't need ALL oversized. If you do it'll be WAAAAYYYY too tight for street per my above post. Just one oversized is FINE.
Has anyone else ever tried that intentionally?
Not that I know of.

Racing Beat used to carry them. Mazdaspeed might let you order them if you send pictures of your autocrosser being built and supply an estimated completion date.

Ok, So I found the oversize plates at mazdatrix! http://www.mazdatrix.com/g8.htm
and it says that it takes 4 plates, and also u can get thrust washers to increase the clamping force even further. I checked the specs in the mazda FSM and it says that u can oversize the clutchplates .1mm and the thrust washers .2mm (same as mazdatrix offers). So after reading all this I am led to believe that buying the 4! oversize plates and the thrust washers everything would still be inside mazdas specifications, with that in mind does anyone not reccomend doing this?

A friend of mine has a welded diff in his 240sx. He has ran it for a year, constantly beating on it, it has taken a whole lot of drift abuse, donuts and burnouts galore, and still holds up fine. It chirps a little on low-speed turns, but hey, it's a no-slip diff. Just weld the bitch up, And Enjoy!

I'm in the process of welding mine up at the moment. I'm going to weld steel plates inside the carrier to make it stronger. I'll take pics when I'm done.
