i am getting nismo 3.9 gearing in the back and want to do the LSD at the same time because its cheaper that way (with labor). so my question is should i go with a 1.5 or 2 way diff. (why/why not) and which company. Thanks for the input.

 

Post this in the drivetrain orum for a response.

1.5 for regular day to day driving, 2.0 for strictly track or if you like drifting

 

I had a Nismo LSD in my car for a couple of months and for me it was way too agressive (and anoying) for the street. It was constantly popping/locking on any turn. I pulled it out and replaced it with an ATS Carbon LSD and it's great both at the track (road courses) and on the street.

 

You should have just rearranged some of the discs.

Generally, a 2-way is going to be too aggressive on the street. 1.5-way is usually what's recommended if you ask any of the producers.

 

the only LSD that works and feels like an open diff is Quaiffe!! (Not to mention it's the only gear driven LSD available) The other brands use plates which pop and crackle @ low speed cornering

 

Really? You've tried all of them?

All you have to do is adjust the clamping force by re-arranging the drive and driven plates. The Quaife is great for road course work, but the clutch type are much better for any kind of drag racing.

 

that's not true - search and you'll see

The Quaife is good for the street...it's less than ideal for anything else though (serious road coarse, drag, or even cars with stiff suspensions). I have a Cusco RS in my car - it is silent, and does not pop or make any noises at all

 

^^^ Yes, what he said ... I also have the Cusco RS
