A spool will give you far better and more stable braking than a Ball diff. But a spool will decrease the inital turn in on at corner entry but will pull and carry more speed through and exiting the corner. you will have to soften the car up to get some steering back but a spool should be faster than a ball diff.

A spool will not make you faster in all situations. IT all depends on the track and what the surface is.

On tigher tracks, a ball diff is faster. On high grip tracks such as carpet, a diff is always faster again.

Actually, you will always be faster with either a one-way or a diff than you will be with a spool. Meaning that if a spool is faster than a diff, on the same track the one-way would be faster than the same spool. And if a spool is faster than a one-way, on the same track a diff will be faster than the same spool.

And actually the only time you ever see spools on the track are when one-ways are not allowed such as the Reedy Race.

I would say we are seeing more people running spools in their cars than one-ways and diffs out in California (asphalt). A spool is great when you have a long straight with a 180 at the end, a spool will be much faster than a oneway. You can come in hotter than a one-way and accelerate out just as fast as a oneway.
Disadvantage - more tire wear, and less inital steering.
