Default How to know when to choose a spool

What are the factors that would make you choose a spool over a normal diff?
I know when to use a one way as thats on open and flowing tracks where the brakes aren't needed much.

To be honest if the tracks not suited to 1ways I use a spool. Its almost always quicker than a diff. What surface are you talking about? Thats also a factor when I make a choice.

Basically its low grip tarmac and reasonably tight.
I ask as I've got a spool in my Cyclone at the moment and have a diff built ready if I need it. From past experiences from other peoples cars they seem to loose a lot of mid corner when its a tight track.

To use a spool you get your steering from getting on the gas and it pulls the car kinda, so in low grip I don;t think it would work to well. Just try it and see, no matter what anyone says on here you still have to try it to see if it works.

For me, a diff on carpet and a spool everywhere else.

I go by the track layout.
If it's tight and small, spool is the only way to go.
If its large and flowing, I want maximum corner speed so I use a one-way.

There are some instances where I choose a spool over a one-way because it is easier to drive. It may be a tenth or two slower but way more consitent, which is sometiems more important than sheer lap time speed.

If i have to run stock (27t) it's always a one-way.

If the track requires that your going to be all over the brakes, then a spool is your best choice. If the track is open enough to use little or no brake at all then a one-way will be better suited. Both a one way and a spool have a major advantage over a diff simply because both are solid on-power, whereas a diff could potentially slip and that could result in a small loss of power. A diff will almost always be easier to drive over either a one-way or a spool, but, chances are it will be a lot slower on the stopwatch.
