we can get Kaaz, we just don't stock it (it's on our site)

the Tomei is listed on our site.

Better off keeping this as a review thread, since all of the questions about compatibility, etc has been posted many times in alot of different threads

Z1 was correct about the OS giken diff. It is not a direct swap. Just got an email from OS Giken USA confirming it.

Anyone have experiance with CARBONETIC difs? I have heard and had nothing but good experiances with their products. Clutch style LSD yet it is very quiet and smooth. The dif can definitly take a beating.

Change it with every oil change. The oil used to be expensive but they just released a much cheaper oil so the oil changes arent too bad. Definitly worth it to get the performance of a clutch dif with the reliability and drivability of a helical diferential.

Type of Driving you Do: Daily Driving

Type of conditions you live in: Chicago--rain, sleet, snow, and sun

LSD Loudness: 1/10. I hardly every hear anything coming from the diff.

Overall Impression: Great Upgrade to those wanting an aftermarket LSD without the associated noise and maintenance that accompanies clutch pack diff's. Only downsides is the price which is a bit high, and if you have a stock vlsd, you have to get axel stubs from an open diff.

Recommend to Others?: Yes! Requires no maintenance, other than the occasional diff fluid change (I use Slykolene and change it out once a year). Also Quaife offers a lifetime warranty for street use and racing!
FYI
They sell a new version of the Quaife diff now for LSD model 350zs, so you dont need to buy anything other that the diff and the standard rebuild parts.

link? I love my Carbonetic diff except when the time rolls around to change that d@mn fluid, again, and again, ... and my stupid pump stops working for reasons that defy physics halfway through the fluid change, grrr... I'd pay twice as much for packaged fluid where you can just squeeze the fluid out!

Give Forged a call. The new retail on the oil is $50. Half of what it used to be.

hmmm. That part number was around when I purchased, but was told that it was not available. Can anyone confirm whether they actually have received this "new version"?

im curious as to the difficulty with converting the cusco rs from 1.5 to 2 (kind of a noob when it comes to some of this stuff). im looking for a diff that would be good for dd and weekend drift/tracking. also does anyone know what diff is in the 35th anniversary?

you're better off leaving it at 1.5 way in all honesty, unless all you are doing is drifting. There is a small cam on the inside of the diff- it gets rotated and that changes the "grind" that the cam uses.

thanks Z1. with the rs using springs to dampen the initial torque on the diff, does this make it have less up a quick lock up with city driving? a friend of mine has the tomei 2 and hes got a pretty harsh lock up even with easy driving around town

you're talking milliseconds less overall "response" time. The solid disk style, which Cusco offers in the Type MZ (not stocked in US) is this style. The spring loaded version (RS) is infinitely more civil than the MZ

Sounds like unless you're doing heavy track or drift events...quaife is the way to go.

I wouldn't agree with that necessarily - it all depends on personal preference. The fact of the matter is there are several excellent options and it's really up to the consumer to decide what their own needs/priorities are - like any other mod you do, it's a balancing act.

+1...True.. I think the majority is def going to side w/ good LSD that is suited for aggressive street driving and mild tracking. Have you rated a Z w/ a quaife installed and compared it to the RS in 1.5 ?...and as to which one put the power
down more effectively ?. 99 % of the people I talked to esp. in socal have either experienced one or the other. On the flip side, occasionally your going to come across a avid track monkey that occasionally streets his car. - thats a dif story.
