Guard lsd cost?
Thinking of an upgrade...what’s the cost of a gt guard lsd and what’s the typical install time? Seems like a better option than quaife due to adjustability and braking, yes?

I’m having my transmission regeared at the moment and am upgrading to a guards lsd. Cost is $1800-$2k. Can’t speak to the install time since I have the ngine and transmission out of the car during a winter of restoration.

I have one. Fking awesome. Worth every penny. About 2.5-3k for the diff. Install is a few hours. Need bearings seals and shims. And proper tools to set lash. Figure 3-4 hours to do it right plus parts.

I am thinking of doing the same and was trying to find an OEM diff to recondition. RARE. For a C2 at least.
Why Guard and not Quaife?
I checked pricing for a Guard and they are out there for $1500-$1700, where do you get the $3k number?

In another thread, I recall reading that Guard had to up their pricing recently thanks to the POTUS's new tariffs on metals.

There are several Guard models. I have them in my other cars. I have beat the crap out of the one in my RS and it's lockup is still at spec (like 1000's of aggressive track miles w/ sticky tires). I don't know the full range pricing, call any guard dealer they can tell you.
I have the stock LSD in my car, it was spec'd with it. I wouldn't bother.
I have the GT2 PRO in my car. They are about $3k.
No idea what the Club costs.
Now the Pro+ which is really at the next level big HP cars and pro racing. Its a WORK OF ART.
Personally i would not put a TBD in my cars. You want them to work under acceleration and deceleration. 911 under threshold braking can get very tail light, the diff keeps the rear end planted.
Guard Diff Options:
GT3 Club GT2/GT3/G50/996/Turbo/968/Boxster S ’00-’04
GT2 Pro GT2/GT3/G50/996/Turbo/968/Boxster S ’00-’04
GT1 Pro+ GT2/GT3/G50/996/Turbo/968/Boxster S ’00-’04
Club – 1045 Billet body, still far stronger than any Porsche or ZF LSD. All of our LSDs come standard with 4 friction discs, however, 6 or 8 disc versions are also available.
Pro – High Strength, hardened 4340 Chromoly billet, 8620 cover, multi disc
Pro+ is 100% 8620 billet

You can install these with the trans in the car, correct?
And they are the same for a 964 and 993 trans? So if I had a 6 speed in my distant future but wanted an LSD for the upcoming season, I could transfer it over when I install a 6 speed without having to buy a new diff?

We strongly advise against doing LSD installs in car. Backlash is something set to 1/100th of a mm using a special factory tool. Getting it right is infinitely simpler on a stand. And getting it wrong doesn't just make your gearbox noisy, it makes the ring and pinion eat itself in 10,000 mi or less.

Cool timing on this. I was able to purchase a "new" G50/03 and I'm considering LSD for it. Are there any setup instructions for the nerd in us? 
I've setup a few rear ends over the years but no transaxles - is this something that I could do with relatively low risk?
Thanks
