Sorry my friend Quaffe dose not make an LSD for the S2000 I have spoke to them about it and there response was that the LSD in the S2000 is good enough that there is no reason for them to try to improve upon it.
It's on their website as available. Saw it there back in April when my diff blew and was considering options.

OK, lots of typing ahead.

to start, my recipe has been working quite well thus far.

this is to keep ap1 from breaking diff casings.

A: install ap2 diff case, and whatever R&P you want.
B:install ap2 slave cyl at same time.
C: install ap2 rear struts for better valving, car then squats hard on launch.

these steps alone, have 2 guys i know smiling like a donkey eating thistles.
no breakage, and killer launches.

2nd bit of info, i just installed the first quaife diff in an s2k (in vegas), and the owner is NOT happy. so hes working with quaife at this point. the augers seem to have alot of play, and so when you apply power, instead of having to move .003-.005 thou,(like stock instant transfer) they prob have 15-20 thou. and so there is alot of slack in accel and decel situations. he is unhappy with it, and exploded a driveline launching it. ill keep you updated on his progress, and quaife's comments.
i wanted this diff bad, but i also wanted the ats diff, or the mugen. because i wanted a clutch type, so i can really rip it out of the hole. we shall see what i end up with.

So PUDDY reinforces a diff.? What's different than the Comptech?

It seems it's hard to say what's a bulletproof rear these days. I hear the Nissan R200 is pretty stout but it's expensive kit and it's very heavy. Would buying an AP2 diff. w/4.56's and cryo treating the whole package be the strongest set up out there?

Your title says more about you than you know.
"raced a bunch of cars last night and my rear broke" ---
This should read: "raced a bunch of cars last night and I BROKE MY DIFF".
I agree with R3DS2K, iam7head, s2krey and FMINUS.
It broke for a reason.
The S2000 is NOT a race car. Street racing is not only illegal, it's considered "abuse" by all manufactures and no warranty will cover abuse.

How is street racing from a 40mph roll any harder on the car than taking it to Mid Ohio and running the hell out of it for 10-15 laps? You're shifting as fast as you can, running the car to redline, etc. However, on the street you're not using up brake pads and rotors, eating your tires, and wearing out the shocks at a quicker rate. I'm not an advocate of street racing but I'm JW why you're making it sound like it's harder on the car than a track.
