Up until recently I was sure I was going to use a Quaife diff in my next car project. Then I read a bunch of comments saying that, on a road course, a clutch-type LSD is better (faster lap times.) Actually, I think that thread was here.

If I'm looking for a clutch-type LSD for a base RSX 5sp, what are my options? I don't see non-S LSDs listed on various vender sites. Will a type-S LSD plug right into a base-RSX tranny?

 

why do you want to run the 5 speed tranny?

 

Low boost turbo. Not logical for trackdays, but I've always wanted to own at least one crazy turbod car before I'm too old! Since the turbo seriously pumps up the torque, I don't need six gears.

Besides, the turbo keeps the car quiet so I don't get busted by the sound police at Laguna Seca.

 

It's also an easy job to fit a "B" Series ITR LSD to the RSX Gear Box.
Save a few $$$$.
I have a good one ($350.00) that I have just removed from one of my JDM Type R K-Series Gearboxes. I'm replacing it with a Cusco.
I also have a selection of GEAR-X Final drives

Hmmm, PM'd.

 

KIWI knows his transmission stuff, he'll hook you up.

I am not convinced that a clutch type LSD is faster on a road course than a Quaife. If they were, I don't think the Quaife would be as popular as it is. I think there are many competitive cars that run Quaife LSD's.

 

A clutch type is superior to a torsen when one wheel is off the ground. However, it pays a price of increased corner entry understeer and high speed understeer. It's also more intrusive then a torsen. I have a really hard time believing you'll see a large enough improvement in lap times to justify the cost. If you can, drive both types and see what works best for you. I find I prefer the seemless action of a torsen diff. Others really like the abrupt, wheel wrenching engagement of a an aggressive clutch type. Saying one is better then the other is like saying apples are better then bananas.

 

Wheel wrenching... oh yeah, you guys are all FWD, Mine will be mounted mid-engine

Ehhh not so much. At speed i couldn't feel any "wheel wrenching engagement of an aggressive clutch type". And that was with a brand new clutch diff.

Keep in mind, I'm playing around with this stuff in 1st-2nd gear on tight courses with lots of grip.
