So I have just won this little fella, a R180 3.9 lsd from a Subaru STI.

I hope to do something like this with the cv's:

But if not I might settle for this:
http://forums.hybrid...ight=subaru lsd

Anyway funds for the car are very scarce atm so unfortunately I might not have any updates for a while.

Thats what I'll be buying for my zed and I'll be going with the beta motorsports side axles, keep us informed of which way you go.

Are the suby cv's known to be weak? I thought this would be a decent upgrade from the stock uni's?

Nice  :)

I've seen a lot of STI's do a lot of very hard launches without busting drive shafts.  If anything the gearbox or clutch seems to be the first thing to go in them.  So I'd say they should be well and truely up to the job.

Bluerat has done some navigating in an ex Cody Crocker car so it might be worth asking him if that was running standard drive shafts?

I was fiddling around with Subi diff's for my 1600, and found the below diagram on Ozdat a while ago, never tried it, might be worth a try if you know a top machinist and welder? I'm sorry I dont know the original author of the diagram, so I cant give credit where due.

As for the rallycar, it's a bit of a bad example, he's very hard on thing's and they get a pounding!! I know in the old car, a MY99, the drive shafts got rebuilt every 2 events, mind you the front diff and dog box went back to Mr.Frank at Modena for a full rebuild after every 4 events or 500km! told you he was hard on it. He changed to the fancy $1500 per driveshafts and they lasted a lot longer between rebuilds. I'm not joking when I say it cost's more than $50 a competitive km with these puppies!!

After all that, I'd try the Subi halfshafts, if it's a R180 then most likely it's STI which are stronger. Hope this helps a little. I have a R160 subi LSD for sale if anyone wants one for there pedal car or Subaru??

Yeah the whole process was very quick and professional. Emailed back and forth for about 2 hours working out shipping etc and he had them posted within 24 hours. More than I can say for some other Z suppliers I have dealt with...

+1 for me too.
Got my Tokico shocks off him  ;D

How much were those adaptors? Look's awsome.
Hollinger have a machine that can make something like that in 1 operation.
Interesting to know what they're worth.

Those axle adapters are awesome.  The HybidZ thread is a very interesting read.

Does anyone know the ratio of a 1998 STi diff -

That's the same seller who stocks R200 longnose LSD's from early Skylines etc.. Just send a question if you need one. Avg price was $990.

aaahh  not a bad score then , i dont think the cv shaft from a suby would hold up in a zed very long


Why??? plenty of overpowered rear wheel convverted STI's around.......
i think 500+hp sti's and and wrx's are a decent comparo??? remember the cv is inherantly strong torque transfer mechanism than a uni joint no?? aswell as more efficint without any speed variations/pulsing???, you would be suprised....

The standard subi stub axles are still the weakest point. They snap before any breakage of CVs unless modified stub axles are used. It will be interesting to see how our imported stub axles handle the Zed. I'm not too worried about mine as I do not have high HP. But then again it is torque that breaks them.
