Yes, if you never want to turn left or right.

Yes, if you like replacing axles often.

IMHO, In other words.. NO!!!

they're definately streetable, just not in a stock 10 bolt rear end. what i've done in the past is wire up an electric washer pump, like you'd use for your wipers and install it in the back of the vehicle with a washer bottle. then run two lines to each wheelhousing and drill and tap a sprayer for each tire. then when you want to turn you just flip the switch which will wet down the tires and allow them to slip around the turns and you can continue on your way.

If you like worn out tires and broken axles then Yes. Otherwise it is a terrible idea, same goes for mini spools. With this knowledge go forth and do no wrong.

The trouble with a spool or minispool is that it locks both axles together. This is fine for straight line driving or circle dirt track where tire slip is normal.

When driving on the street, you need some sort of differential action. When you turn, even doing a lane change, the inside tire has a shorter distance to travel so it turns less. The outside tire needs to turn more.

When the axles are locked, this prevents the outside turn to turn faster and it will slip across the pavement and lose traction. Other issues such as worn tires or broken axles can come from extreme forces caused by the spool.

For street use, a high quality posi or any other locking differential (detroit locker etc) is recommended. It will perform as good as a spool for straight line accelleration and give safety by providing differential action in turns for street use.

You're not going to find a full spool for the tiny 10 bolt and mini spools are only designed for dirt track racing.
