I road race a '94 Integra GS-R in SCCA's ITS class, and am looking for advice on a limited slip.

This car is 100% for track use only (no street at all) so I want the best suggestions for a no-compromise LSD (and at a reasonable cost).

I'm leaning toward the OPM clutch-type LSD. It seems very aggressive (probably track only) and at a devent price ($650).

What do you guys use?

B17? If so... OEM or Quaife will be fine.

Welcome to the forum. Looks like more are more GSR are starting to show up in ITS. Good sign.

I run an OE Honda LSD in mine. Low milage used units are cheap, they work, and are very robust. If you have the budget, the more aggressive clutch type units are the way to go. AT $650 the OPM unit is a great choice.

 

I bought an Integra Type R diff second hand on eBay. Works good.

What region are you racing in?

 

I believe I have a Type R LSD in mine.............but I understand OPM is the way to go........

 

My old car (now Maxx44's car) had the OEM Type R diff. It worked well.

My new ITC Civic has the OPM diff. It is very noticeably more aggressive. Most all of the top ITA guys around here use it as well.
Its apparently also pretty bullet proof. I have rarely heard of failures and it was actually pretty much the only thing that survived in Adam's box when it gave up at last years ARRC.

 

I had an OPM diff in my street Prelude and a KAAZ in my GSR race car. There is no comparison. The KAAZ feels like a welded diff at parking lot speeds. On track it slips like it should but I can tell that it is actually working. I never really knew if my OPM was working. It just did not seem very aggressive. Granted, this is in a 2800 lb car. My tranny grenaded soon after I installed the OPM but I am 99% sure that the guy who pressed by bearings on accidentally pressed on the races and screwed them up. This is the general feeling I get from talking to people with the OPM diff. In very light cars people seem really happy with them. I have talked to 3 people not including me who ran them in heavier cars and all said they were not sure if the diff was working. Just my .02. Not badmouthing OPM either. They kick ***.

Edit. I must have fell on my head today. I have a KAAZ not a Quaife.

Not to ***** the thread, but I have a brand new, with fluid, Spoon 1.5way clutch type for sale in the buy/sell section of this board. It has a little more aggressive action than most clutch types (kaaz, etc).

I like the clutch types because they are usually lighter in weight than the gear-driven units like the quaife and the OEM ITR lsd. Personally, I prefer the feel of clutch-type too, but the oem ITR works better than nothing.

FYI '94 - '01 integra GSR would be the B18C1 not B17A ('92-'93 GSR) motor.

I haven't raced (auto-crossed) with my G2 Integra yet [it's still in pieces and needs lots of work], but I decided to put in a Quaife ATB differential mainly because there will be less maintenance to worry about and I won't have to break it in like a clutch type LSD differential. Anything beats an open diff...
