Open Diff vs Helical

[RM1SepEx]

My Quaife was very nicely finished with their logo lasered into the side. I have pretty extensive background with precision machining and the Quaife is very well machined. It did come in an ugly plain cardboard box tho LOL

The link I posted explains why they need to be rebuilt. They are so cheap because they are a Chinese made forgery of the Quaife unit and therefore do not have to recoup engineering testing or development costs.

the quality control on the Quaife is better and comes with a warranty, you are paying for that as well.

How about the Tomioka brand helical gear type limited slip? Any experience with it? Costs about $850.

All I know is for about a grand you get a lifetime warranty with the Quaife, I have tons of friends that swear by them... That Tomioka looks like a quality piece in the photos

If your going to spend the money on a subaru tranny and get the best quality and durability street or track it goes 1. Cusco, 2. Sti gruppe N 3. Quafie and all others are no were near the three. I have used all and I like the cusco the best, but the others are spot on as well.

Autotech took the part down, bummer!

Interesting, I can get the Cusco here for a decent price ($800), it's the Cusco Type RS Spec-F. One of the reasons that I want the factory LSD is because I've had pretty bad experiences with aftermarket LSD's in used-cars that I have purchased. They have functioned well, but they also are very clunky, noisy, and I just don't like the feel and sound in low speed situations like parking lots. Is this about the same as the experience with the Cusco LSD as well?

Perhaps they sold out!
if $ is a big concern buy an OBX and rebuild, Erik has a great tutorial on this forum. No lifetime waranty but about $500 will get you an OBX with the parts needed to "fix" its shortcomings... The Sube forums indicate that they will hold up if the springs and bolts are replaced.

[bnr32jason]

Are there any aftermarket front differentials that are quiet? Or are they all noisy?

How about the OBX? I've dealt with noisy diffs before and it's annoying. I'm not building a track car, so I want something quiet. I'd honestly rather go open diff than have a noisy diff.

[Wayne Presley]

the OBX, quaife are both quiet gear type diffs.

Oh ok, thanks for the information. I'm still pretty new to this stuff.
