Difference between OBX and Quaife front LSD

Why, they both come with "Limited Lifetime Warranty. This warranty applies even when raced". It takes me a hour remove my transmission and a hour to put it back together and back in. I have a spare transmission also, so if this works well, then I'm golden, if not I'll go back to stock or the quaife. If Supercar is selling them, then they are a good unit. He wouldn't sell it if it wasn't. The only bad reviews I've read on this are from people that have never even seen the unit, and never even tired it. I'll even be the test car and keep reviews on it after I have it in the car.

ask yourself this question. Which "lifetime warranty" is from the more credible source?

OBX a french ebay company that makes cheap knock offs of good parts. Parts which many owners here complain dont even fit well or are not so good quality. (case in point OBX headers) And who RECENTLY started making LSDs (2005)

or Quaife, a highly respected british company, whose sole purpose for the last 40+ years is building drivetrain parts. They've been around from the 1960's. Quaife also has numerous race wins behind their belt, and also is the OEM LSD manufacturer for many cars.

Building on a budget is one thing, but my view is if your gonna be spending that much cash, might as well spend it on something that you have no doubts is going to last, and also take a warranty from a company that you know will be around for the next couple of years.

Their a couple companies that most top tuners know make good products and only run their stuff, KW, Ohlins, IHI, MHI, Quaife, Borg Warner etc.

OBX is for the rookies, Quaife is for the big boys

Now heres another point.

Visually they may look the same. But so does a pile of shit look like melted chocolate.

What seperates the two? the composition.

Its the very nature of a gear type LSD, to be able to take alot of abuse, but the strength of the LSD will depend on the strength of the gears which its made of. The strength of the gears, will depend on what materials they are made of, and also how much time and money went into their design and testing.

It might be the same looking gears etc, but I am very confident in saying that the OBX diff, didint go through even 1/10th as much testing and R&D that the quaife unit went through.

I can tell you this, two gears can look EXACTLY the same, have the same ratios, hold the same loads, but then run them in a machine, one gear last 1000 years and the other lasts 10 months.

The difference is in the metallurgy, things that you cannot see with the naked eye.

Quaife parts cost that much because they cost alot for quaife to produce them. OBX is just a knock off company, in it to make as much profits as possible and get the hell out.

This debate is like pitting Defi vs. Prosport, Recaro Vs. Tenzo R, snap-on vs duralast

If you need more proof of what your paying for, read Quaife''s warranty statement. The Quaife warranty is a lifetime one even when raced, and it extends to the life of the car, all subsequent owners of the car, and all subsequent owners of the LSD. I.e. I can sell some one my difff 20 years from now and if it breaks they can send it into quaife and get a new one no questions asked.

I highly doubt OBX would back something like that. Their warranty is most likely based on their testing. They know their making crap, so sell them cheap, make as many as possible and dont put as much money and time into making them. If 1 or 2 fail they can send the customer another one, and the amount of money they will make from the 1000's that they sold will more than compensate for the 100 or so people who will have a diff that failed.

I'm pretty sure their warranty is "while supplies last" even if they dont explicitly state it.

Any reasons in particular?

Missed that post. Thanks.

I was reviewing some threads about OBX LSD's in other platforms and I came across some info that might be of use for those buying an OBX LSD. See here: OBX Differential Washers and here: De-mystifying and Bulletproofing the OBX LSD (Re-born) - Club RSX Message Board

Here is a good comparison of the two diffs:

OBX copies a lot of Quaife designs, including this one. I have inspected every one of them, and added Loctite to the bolts that hold it together, just like Quaife does. I believe OBX will be able to stand the same abuse. It offers the same warranty.

Okay, here is one reason why you might want to choose one over the other. Quaife appears to have a better finish on the gear teeth. It costs money to produce a better tooth finish, so it makes sense that it is more expensive. From my personal experience I can tell that Quaife provides a more smooth and consistent operation from the very beginning. OBX seems to be more aggressive initially, due to the initially higher internal friction, but after about a week of driving it breaks in, the gear surfaces smooth themselves out, and you cannot tell the two apart.
Still, no special break-in is required for either diff.

It looks like this was overlooked. Seeing how SC is highly respected here, I don't see any reason not to trust this statement. Just my .00000000002

As I said before A warranty from a company thats mainly associated with ebay, and has no motorsports credibility means nothing

I dont doubt Supercar's words, but I think what hes saying is for the money its ok stuff. To even say that they are remotely close to the Quaife is a very big stretch.

The Group Buy for the OBX diffs is here. It will run til the end of the month of October. We have already sold 3 OBX diffs, so the new math is this:

.....2 people - $745.00 ($50 off)
..7+ people - $695.00 ($100 off)
