LSD: Quaife vs DC2R
Can someone tell me what's the difference between them?

Have you tried the DC5/EP forum?

 

I'm not sure if the DC5R uses a torsen style diff like the DC2R, but if it does they operate in a very similar fashion. Both are mechanical torque-biasing diffs that use gearsets instead of clutch packs.

The most obvious difference when holding a Quaife next to an OEM DC2R torsen is the quality of construction. The Quaife uses a billet steel housing instead of cast steel, and appears much stronger than the torsen.

 

so which one is better on road race?what diff?

 

Probably the Quaife, due to its heavy duty construction and lifetime warranty that specifically includes use as a racing part.

The general concensus here is that if you already have the stock torsen there's not much point in buying the Quaife, but if you are purchasing a diff the Quaife is worth the few extra bucks over the OEM unit.

I've never done a back-to-back comparison of them on a road course, so that's as helpful as I can be on the subject. Good luck.

I agree with you except for the fact that we have recently seen some startlingly cheap DC5-R OEM Torsen units for sale on eBay.

However, if you cannot get one of these very cheap OEM units, I would definitely get the Quaife.

(Please remember, too, that these cheap OEM units will only work with the 6-speed RSX transmission. They won't work w/the 5-speed EP3 transmission.)

Oh, OK. I didn't know that, since I'm not in the market for DC5 parts, but thanks for the correction.

 

but why the racing team (REALTIME) using the oe DC5-R LSD,are they cheap?

 

Aftermarket differentials may not be allowed in the series. It's hard to say, since the rules are different for each make of car, but I know RTR was allowed to use OEM DC5R cams in their cars, but not aftermarket cams.

Just guessing, but I'd say that's probably why.

 

The DC5R LSD is just like any other Honda LSD , they work but an aftermarket one is definately going to be tougher... Quaife & Kazz

EDITED: Yea my bad I just hate sounding repetitive, in this case it might have made the subject unclear...

The Type-R diffs are like any other Honda LSD, most hondas come with an open diff, the LSD diffs are Helical gear diffs and yes can be had for under @600.00 on e-bay...LSD cars are the DC2R, 03CL-S 6-sp, and 04TL 6-sp.

 

anymore details in specs?

 

Just want to leave a brief not that there are a couple of people in Sponsors Marketplace who appear to have very good prices on Quaife differentials.

The OEM Honda differential will be cheaper.

But if you're afraid of something used, or afraid of getting cheated on an eBay auction, they do have good prices on Quaife.

 

We found that in road racing the older Type R Torsen Units were breaking. When guys would get one tire airborne several times during a race, the reverse loading was to much for the stock lsd to handle. The little worm gears inside the diff would snap as far as I know. We sold a small number of GSR differentials to Type R road racers who had failures during road races. Hondas racing department sent us a Type R lsd to prototype the current RSX/Si diff with and it didn't look to different from the older Type R Integra diff. I would assume they would suffer from the same problems. BTW, Honda told us that the RSX 6 speed, and the Civic 5 speed use the same differential. Just some food for thought.
