if there is one thing i've learned in all this car bullshit... do it right the first time.

regardless of data (which is always nice to have, haha) i feel that a LSD device that is based off of the priciple of having two peices of metal grind up against the inside of your differential (in a way it wasn't designed to) is just not a product that should be invested in for the long run....especially making the power you want to.

yes, it works to an extent. it's also economical....however i'd do what i think you're preparing to do and buy a real LSD.

- JustinG - 04-11-2005

well honestlt it is phantom grip or nothing, cause , my budget wont allow purchasing a quaife....donations are accepted

Oh yeah, they ditched the clutchpack and went with a torsen. 1000 HP Killer "B" Audi Quattro? Yeah, it had a torsen. S15 Spec R Silvia? Torsen. Integra Type R? I'll give you two guesses. Yeah, it's torsen.

Thanks for the lecture Rex. From now on we should all take a cue from what car makers do in their production vehicles when discussing performance related components. I should have just stuck with my t25 because hey, that is what mitsu put in the car.

Hey, nobody has any complaints with the Evo, and it has a Torsen, too. (Well, some of them.)

Travis, don't be a bitch. My point was that he said that "manufacturers use clutch differentials" implying that we should, too. I even quoted the website you gave us. My point was that he was wrong. Furthermore, I'd like to point out that 99% of the models I listed were the top-of-the-line highest performance models. So yeah, most of the time with that sort of thing, many factories have it pretty close to perfect. Not all, and certainly not with a DSM.

But the fact remains that there was a factory performance part on DSM's that would make YOU faster, and yet you don't have one. How strange. Maybe we *should* take a clue from manufacturers.

Also, quite being such an asshole. It's getting annoying.

- KPWSerpiente - 04-11-2005

He said that racing teams used the clutch type. Nothing was said about car manufacturers who have to worry about how the average idiot will use the car.

If you are implying that a completely different drivetrain is a 'part' that would make me faster....well I think that is a little misleading.

In fact Rex...I didn't say a thing one way or the other on this topic. I just pointed put up a link to what Passante had to say. I'm not really that interested in the subject matter.

Clutch types arent bad - but they have several disadvantages.

- Cost more up front
- Require rebuilds (every year if you want to keep it fresh)
- Require more expensive fluid and more frequent fluid changes
- May require changes in car setup and/or tires
- Require break-in
- Not street friendly

A torsen/quaife will be cheaper to buy/operate and 'easier' to have in the car. All comes down to what is best for your application... E30/E36 BMW's use clutch packs for their LSD's - although its a fairly low lockup ratio (25%) - I'm not sure what other cars came with them.

I have a Torsen. For roadracing the quaife would be the BEST choice. Clutched LSD need not apply. You always need to look at Torque sensing diffs. Of those you have the Torsen and the quaife. The Quaife is the best. I just couldn't afford it at the time. Wish I had now.

For a race car that never sees street use, I wouldnt seriously consider a clutch diff - depending on how easily it can be serviced stateside.
