Not many cause if you are going to drop the tranny to put in an LSD, be ready to regear and add a stronger clutch. No need to stress the rest of the tranny by just adding an LSD, and slipping the clutch.

I have to disagree that a 155 whp car doesn't need one. Technically, the Quaife isn't an LSD but an ATB (Automatic Torque Biasing differential), and it's a wonderful thing. I will, if possible, have one in ever car I own from now on. Not only is it a blessing in good weather, it's been fantastic in this Michigan winter. Traction in snow is greatly improved, especially if one wheel is on slippery stuff and the other is on dry pavement.

When I originally called Mazdaspeed to ask about the Quaife, they told me that it was a race only part. Their words when I asked why Corksport was able to sell it were something like, "Yes, Corksport is our 'out' to allow non-racers access to this part." Corksport charges even more money now than when I bought mine, though!

Even at the $1541 I paid for it, it's been worth every penny. Although it doesn't increase torque steer in a straight line (it actually seems to reduce it in that situation), it DOES increase torque steer if you hit the gas while turning the wheel from a stop. Overall, it's highly recommended if you can afford the price. Theoretically, it should also reduce understeer while accelerating around curves, since the outer wheel will tend to get more torque sent to it than with an open diff. It also has by far the best warranty I've ever read for anything. It's warranted for life, even if you race, regardless of how much power you add to your car, as long as it was installed correctly.

I had the guys at my dealer install it. it's got a few adjusments that have to be made in order to fit right but nothing that an experienced shop hasn't probably seen yet.

Yes, some gearboxes have the parts already fixed for this and some don't. Mine fitted perfectly with no mods, but my friend's did not. We had to grind off a little on the selector guide.

I had the performance shop that I've been using for my last three cars and trust completely do mine. They have more than 30 years of experience hot rodding (in addition to being a parts store and "normal" mechanic shop). They had no problems with the install.

I have the SPEC Stage 2 clutch. It's OK. I'm not a huge fan, but keep in mind that I've never had an aftermarket clutch on any of my cars. It's never been necessary before, but since I plan on going with HiBoost on this one, I decided to do up the tranny first. The odd thing about the SPEC Stage 2 (which Steve at NSN assures me is normal for this clutch) is that the activation point is at the top quarter or so of the clutch travel, and that has taken some getting used to. There's also a bit less travel for slipping the clutch while starting out in first gear, which results in my spinning the tires a bit sometimes when I don't intend to--a problem that will only get worse with 250+ whp. I'm starting to wish I had just stuck with the OEM clutch until it burned up, and then looked into higher torque clutches when it was truly necessary. I'm not typically hard on clutches.

^^^ the activation point is totallly normal. I have the stg 3 and is the exact same thing. But I haven't had any issues with jerking or burning rubber when i don't want to. Justtakes a bit getting used to. And when you have the turbo it will be no different, unless you release at high rpms.

i really wish these were cheaper. the quaife (<sp) is soo expensive unless you are really a serious racer. hopefully another company will come out with one that isnt so high in price...
