Hi, im not too sure on how a spool diff works and wondering if it would be safe or the better option rather than LSD for me to drive around in my torana. Any help would be appreciated.

A spool diff has the axles permanently linked together. Great for going in a straight line. To go around a corner one of the wheels has to break traction or you break an axle, whichever is easiest.
They are not legal on a road car.
Have a read of this site.

LSD for road car.
Spools lock the axles together and will cause damage in everyday road use as one rear wheel goes faster than the other around corners as they travel in different arcs.

depends on what car you have? i really like my spool and my cars a street car. you get more traction when launching and more control when sliding. then again id only have a spool in a 9" not a bango as thats just waiting for an axel to snap.

Depends what you drive your Torana for... If you just drive it on weekends, on dry days etc.... The Spool will be great fun and you will love it...
If you drive the car a bit, In all types of conditions.. The LSD will better suit your purpose... I had a spool in my 9" but decided it probably wasnt the best option for me (Wouldnt want to do a U-turn in front of a Cop, or try and pull into a car spot with one watching...)
If your budget can allow it, A detroit locker might be the perfect comprimise... I Dont really know how they work. But i believe they are an LSD that also will act as a spool is some cases... Surley someone else will have a better idea...

i dont know why people hate spools (looking at you herne)
i had one in my daily driver vr manual. 'bout 90k round trip to work and home and the spool was great. benefit is it is predictable over a spinner or 'not new' LSD. only problem is cops and tyre wear, but you have those 2 problems anyway depending on your driving style.
now i have one in the uc, but thats not a daily.

Please dont look at me I get mighty scared....
You answered your own question, no further comment from me required.
If it were a track car I would have a different opinion.

If the car only goes in a straight line or does burnouts, spools are fine. For every other application, I have other options I prefer. If people dis-agree with me because they prefer other options, that's OK with me.

LSDs are dangerous because you never know what your going to get. I bent pushrods in my 330 stroker when i put the foot in hard at 30-40kph to plant my mate in his seat. Instead of locking the wheels up and putting the power down it peg legged it and spun the tacho to 8 grand.
Most of the cars I've driven with spools are fine, you wouldn't even know it had one, but some are really violent and horrible. It depends on your setup! I know heaps of people who run them in daily drivers.
I found that in my mate's LH with a 3500 stally and 265/50s, you wouldnt know it had a spool. My understading is that because when your driving on the stally its like riding the clutch in a manual, plus the baggy tyres also take up the slip on mild cornering. Another car i drove was a VN with a 5spd and 18s and low profile tyres and it was also extremely streetable. The trick in car parks was to ride the clutch and the low profiles tyres just spin on tight corners which is good because its not fighting the suspension that way.
When my mate in the torry blew his box and went back to a stock gearbox and stally it became a viloent pig (because there's no clutch slippage).
I wonder how my brass button and spool combo will go... Only time will tell

Ive decided to go for spool diff but another thing im not to sure of is the difference between a full spool and mini spool? Do they work differently and are they both suitable for street cars?

mini spool replaces the gears inside the diff carrier. full spool replaces the diff carrier and the crown gear bolts directly to it. you dont get much stronger than a full spool
oh and a full spool is lighter meaning less rotating mass meaning less HP wasted to turn the diff and more HP to the tires

Full and mini spools are not legal on street cars.
If you are involved in an accident and the insurance company can prove the spool contributed to the accident they do not have not pay.

How much is a LOKKA Rory ?
I've just done some research on them, sounds good so far.
