kazz or cusco

[redbarondrifter101]

has anyone in this town run a 2 way racing diff? the thing is a grand and i wana make sure its worth it. im running a t2 diff now and it gives out on hard deceleration slides, i need more beef!!

[GTIKyle]

Weld it. only way to be

[SRT Brian]

HAHA:rofl:

[redbarondrifter101]

its already a lsd so i dont think there is enough to weld on like a open diff. and it will have a lot of stress!

[2bad]

What kind of car are we talking?

[redbarondrifter101]

88 turbo fc, probably just over 200 but i haven't done any motor work yet.

[sr240]

my friend has a fc turbo 2 with a t66 on it in cda you have probably seen it its the only purple rx7 in this area.. lol..

88 turbo fc, probably just over 200 but i haven't done any motor work yet.

A guy in town had a Kaaz in his S13 240, I rode in that, it is a HUGE difference compared to my VLSD that's factory in some 240's. The Kaaz locked faster and harder, however on tight slow corners you get an occasional hop or clunk from the rear. Hell even a VLSD will make a clunk if turning tight enough. It is a night and day difference, however its a lot of $$ and it really depends what the car is being used for. Also take into consideration the clutch disks will need to be replaced down the road, which is more money, but at the same time, you can basically rebuild your lsd any time you want/need.

[redbarondrifter101]

i only drift it, sometimes auto-x and shows but i have teins on it so it stays inside. does that 240 have a 2 way or 1.5?

the only purple rx7 in the area...that only makes it out of the garage for 2months out of the year



i've heard good things about KAAZ for RWD cars

as for 1.5 or 2 way....i've always believed thats its a driving preference.

[redbarondrifter101]

well this car is driven to the limit every time it comes out, the 1.5 wont lock when u let off. it is a drift car so it needs to act welded. i think i know the purple car but there are 2, one has shaved door handles and the other is little beat up and i saw it by scc.

[Gsolo]

the purple rx we're talking about isn't beat up...and its loud.


if you want the feeling of welded/spooled rear end then as far as lsd goes get 2 way.

[GTIKyle]

Personally, if it were me, and based on what your driving style is with this car...I would weld it. No offense, but the Kaaz diff is a RACING diff...it's typically installed in road race cars (or poser drifters with way too much money) With the expense of tires and shit, i don't think you're going to want to be rebuilding that diff every season (they get expensive)

Welding on the other hand is virtually free, it will give you a pretty predictable kickout....but shitty street performance. But again, if you're not looking for that, who gives a fuck?

My vote is to pickup an N/A rear, and weld it up. They are cheap as hell and easy to find as not many people want them. Run it for awhile, and if you don't like it, swap back for your LSD, or step up to a Kaaz.

the problem is finding a open diff for it, the t2 diff im running is the same as ur fd size wise. idk if the make then open because there all turbo.

[GTIKyle]

My bad..didn't realize you had a T2 diff....
Fuck it, go ford 9"
lol

Edit : you can still pickup an entire rearend assembly from an N/A 7" base model. Not quite as strong, but i have doubts that you'd be splitting anything. Those are what i was thinking of. You could swap the whole thing in for < $100

[redbarondrifter101]

they are very week, that's what i pulled out. the stubs that come out the side are half the size, same with drive line and cvs. im going to be making a lot more power next year to.

what are you doing to your car that's going to make a lot of power and what do you consider a lot?

[GTIKyle]

I ran a mid 12 on a 7" GXL rear, pushing ~320hp through it...it held up. But i did run an auto and wasn't doing 6k dumps to slide it...

[redbarondrifter101]

a friend of mine did a clutch kick and spun the stub off right ere it hits the pumpkin, ill c if he still has it. it looked crazy

[redbarondrifter101]

im going to look at how hard it would be to weld my lsd up, i have a few extras.

You have to pay to play...hence using a very reliable strong LSD unit.

Welding a rear end may be free at first...but when it breaks, or you lose complete control of the car because its welded...then you realize very quickly just how expensive it was.

I am very against a welded diff at all...and against spools except drag only (or circle jerk, i mean dirt)

As far as KAAZ (or anyother good manufacturer) used by "poser drifters" ....i'd have to say that welding a diff is for the posers, using proper equipment is for the people trying to do it right.

Can anybody name me a big name driver or team in D1 that welds their diffs?

[GTIKyle]

Well first off, any rearend failure can cause lack of control. Lets face it, when you no longer have your drive wheels engaged, your options are steer and brake. So highend LSD or not, breakage means loss of control.

And to answer your D1 question, i doubt it. But they also have team sponsers, a budget that makes baby jesus cry, and no reason not to run Kaaz (especially since the Kaaz sticker pasted on the side of their vehicles gets the public to buy their nice and expensive LSD).

I'm not picking on the OP, but i doubt he has a limitless budget. 1k for an LSd is a huge chunk of change, not to mention the fact that with the abuse these units see, its not uncommon for more than one rebuild in a season. And that is not cheap in itself.

Don't get me wrong, its a well engineered device, and i think it serves its applications VERY well. But for the average joe, buying the best shit on the market doesn't always make sense when there are some alternatives that will also work.

[Gsolo]

trust me, i wont argue over paying for any aftermarket LSD

I don't think i could ever drop $1000 for a lsd unit....i'd personally stick with oem shit and rebuild them....but i'm speaking from toyota stuff not mazda, i dont know how well they hold up, or if its clutch even?

[redbarondrifter101]

its not the cheapest build as it is, ive got 2k in suspension already, but it useless when i keep having diffs open up when i push the car! i want something that wont straiten me out but i don't want to rebuild it every oil change! my brother has a welded one in his fc but it was open, mine is lsd stock with less room to weld and more risk of breaking. its quite the dilemma

clutch lsd or viscous?

I'm wondering how well the stock lsd would be if rebuilt? If they're like a 8 disc lsd then i can see not being to awesome after a few hard drifts

[redbarondrifter101]

i think they are clutch, there are layered plates in side it, its mostly in the rain i see it most. as soon as i jump back on the gas it lights up one. the diff should be pretty good still, has 60k on the swap.

[redbarondrifter101]

i emailed a pro and he pretty much said run it

"We do have the Kazz unit in our drift car, if you opt. for the WPC treatment you should get a little more life out of the clutch packs. We have used the LSD all season last year w/o any issues. I have one on my personal car and have had it for over 2 years going to drift events about once or twice a month without any issues. You should be fine for 2-3 years without any major noticeable wear causing you to rebuild it."

[Gsolo]

I was thinking that for light drift use you'd get a few years out of it...but without personal experience I wasn't gonna say it :D

still big chunk of change...but good product

[redbarondrifter101]

the tiens were 1600

Umm $2k is a set of coilovers.

Do they make spools for your rear end?

[Jetblack]

How in the world would you break a spool, drifting a car that light? I have never heard of a properly welded... anything, break. If you weld properly or have someone with training weld it, it should never break unless there are defective spools out there.

It may be that the accessibility of welders has made it too easy for Joe Blow to get his hands on one and have at it, without ever reading the instructions.

Man, I'd be embarrased if my welds broke. Out in the trailer-building world, I guess you sign your welds, on the print. If the weld ever fails, the investigators will know who did the weld and come have a word with you.

I feel like if I was doing drift only, I would weld my diff, in a heartbeat. But aside from making turning much easier, in the pits and whatnot, what is the advantage of a diff that will differentiate around corners?

I have seen spools break...but no not in that light of a car you're right, probably be very hard to break a spool in that light a vehicle with only a few hundred horsepower.

Same goes for a very well welded diff...but no "professional" is going to take the liability, and i've never heard of a "proper" way to weld a diff

And if you're going to have the vehicle on the road at all it needs to differentiate.

[redbarondrifter101]

sway bars, angle tie rods, and 4 piston calipers to. but i think spools are only made for 4x4s from what i have seen. that would be ideal for this but i cant find anything and i have looked for the last 2 years
