Supposedly they are a copy of the quaife design. If this is true then it probably works pretty well (for the price) but I would pull it apart and make sure everything is where its supposed to be.

Ive heard people say they break immediately, and Ive heard other claim they hold up just fine in a drag only car. Who knows?

A quick search did reveal this page. http://rbryant.freeshell.org/obx_washersOf course this guy is trying to sell something so take it with a grain of salt.

Apparently the subaru guys say they are pretty good, but Ive heard of them breaking on little fwd Hondas, so I don't know.

My team mate bought one for his Neon, also has a real Quaife. He took it to work and had the lab do some metallurgy testing on it. Yes, I am serious he is a chemical engineer for Dow. They said it was good besides the bolts that they use. So replace those and you should be good.

IMO if you can afford brand name do it. OBX is a company with one of the worst reps. They are a company that has designed nothing of their own, and has only copied others, and poorly at that so why waste the money.

On that lifetime warranty, I would love to see documentation on what the conditions are.

I thought other knock off companies made copies of the OBX products, like my stainless steel header.

Torsen are good, not as good as adjustable Kaaz 2 way LSD but still better than open diff. Will do you good in cornering. Just be careful of them in heavy rain, they'll act like open diff when one wheel starts slipping.

i do drag the car a little too...so would i still be better off going with a 1.5?

..and who else besides kaaz makes them, theyre kinda pricey!!!

From what I remember reading about these, they work great. Just make sure you take it apart when you first get it and check the spacing between the gears.

Also, if I'm remembering correctly, the hondas were breaking axles with these diffs, the diffs were fine.

Helical and Hydroplane due to heavy rain are bad combination. Not just simple wet road.

Seems like some of you need to touch up on your knowledge of LSDs...

This thing is decent for the money, but one thing when you get it, replace the spring stack. The spring stacks they come with are weak and will fail in no time.

I would change immediately, but I'm sure you can break it in how it comes but once break-in is done, pop it open, clean out the debris, and replace the spring stack (which are dirt cheap), DONE. Maybe re-shim if your not liking how it feels.

This might not be your best choice for drift, but auto-x yes.

1.5 or 2 way for drift.

did lsds are mainly for turning and locking wheels to gain acceleration and control. if ur gonna be drag racing 1.5 is fine or just weld ur diff.

idk if i agree w u Soravia, the idea of a helical is that it transfers more power to the wheel getting less traction, how does that make it bad in the rain? if u have grippy tires and a decent suspension setup i think a helical would help w grip... dont most road racers use helicals for this reason.... i know a local guy has one, (greeneyes) id love to hear his imput

Helical acts like open diff if one wheel loses all traction, as in wheel hopping or open diff.

Wait so a helical is an LSD that works like a regular diff ... Doesn't that defeat the purpose of an LSD. For instance I have stock diff in my 240 and today I got stuck at a bad angle in my driveway and cause my suspension is stiff as hell, I had my passenger rear wheel almost off the ground, and could not get the car outta the driveway for hte life of me. Shreaded down a good mm or 2 before I got some help from a nieghbor and was able to push it out. Had I had an LSD I woulda been able to back out no problem cause the power would have been divided correctly to both wheels and not just to the one wheel with loss of traction.

I mean I understand what a 2 way is and how it works, but the helical???

Helical doesn't lock the wheels, it just shifts the torque levels from one to the other. If it can't get a grip on one side, it can't really do that.

VLSD and Clutch LSD has locking just like a clutch on a transmission, you can make it slip past certain point and lock after certain point.

no it's exactly what you want in a racecar. It sends power to the wheel with the most load on it. It won't lock the rear end causing the *** to come out.

It's just not something you would want when you're backing out of a driveway in a lowered car with a stiff as he11 suspension.

I have a helical and stiff as hell suspension. If you're coming across something where you know you're going to be three wheeling it (like backing in my driveway for example), you just need enough speed to where the wheel is only in the air for a very short period of time. I absolutely love my helical though.

its a matter of opinion what you'd rather have. Personally I'd love the *** to slide in any car I drive street or track, cause IMO it gives you more control of the car if you know how to use it.

And my driveway is steep as hell. Like a 35* angle or so. I was straight across it, and had to turn my wheel down the driveway a bit so i could get back onto the road and not end up hitting my fence. and I ended up three wheeling, with open road behind me and a fence 2 inches from my bumper. I shot a 2 by 4 out and almost took out my neighbors benz trying to gain a little more traction. I even had someone that weighs roughly 230lbs sit ontop of my back right wheel, and the **** still hopped like a mother****en bunny humping.

I've heard only good things about these in s chassis, except for the problems with the spring stack, but that's a couple bucks to replace.

as far as three wheeling, just pull the ebrake a bit to put resistance on the wheel that's spinning, and you'll be able to pull out just fine.
