Default Why no one-way or spool at rear?

Can somebody explain why one-way or spool only used at front and not at rear?

I've heard of people running double one-ways. If you can drive it, it would probably give lots of corner speed. The spool at the rear would make the rear loose and I've run them in nitro but don't think it's a great idea in electric...but who knows!?

Lol. Double One-Ways. Can you imagine everyone running their cars like that at the track? When they brake, everyone will be spinning out.

double one-ways is actually a term that only applies to 2-belt cars, it means you have a one-way front diff and a one-way centre pulley. Nobody i know of has ever used a rear one-way. Not sure why, but i do know why you wouldnt want to use a rear spool; the car would spin out under acceleration due to too much power to the rear wheels (especially in mod) and nowhere for the excess to go except the road, as well as the fact that because the wheels have to rotate at the same speed all the time, meaning you will get wheelspin under power while turning. that's why a diff's there in the first place.

Dude, if you have double one-ways on both the front and rear axles... you will have no braking at all. The car will just coast like a full time 4WD vehicle under neutral power.

Only the drag caused by the ground and bearings will slow down the car.

Ups, a rear spool doesn't make the car to spin. It does make understeer, because you'll need much more force to turn the rear end.
So a front oneway gives more steer, that it will be lost with a spool.
A rear oneway coupled with a front one, will make impossible to loose speed with the motor, so you'll had to neutral much before the ideal point, or... no turn possible !
