About using a spool, I had the same belief (that it would understeer horribly), but on our track (twisty indoor carpet, very low traction, rubber only, no compounds allowed) it seems it's the ticket to success in pro stock and mod at least. Mod drivers tell me you can be very aggressive with a spool and understeer goes away. Also, it allows late aggressive braking points in corners.

On large, open tracks, the problem doesn't exist.
Err...Okay....?

Guys help me out. Do you mount the front oneway diff for better turn in during corner entry?

If so you are basically saying that most touring cars today have a bit understeer at least during entry. meaning they are a bit front heavy?

Not really. Front oneway is going to give you tighter lines all the way around the corner plus higher speed out of the corner. Be advised though, there are a lot of caveats riding on this statement.

Most cars today have an almost 50:50 weight balance.

I meant to say braking in a straight line, not necessarily on the main straight. I didn't think anyone would discuss brakng when there's no reason to.

I agree. I have this debate about once a month at my track

For what it's worth I'm a one-way guy for stock and spool for anything faster.

You'd think that having a solid axle in the front will give you horrid understeer, but that isn't the case in TC. I would like to try a oneway set up on my TB03, but for consistency, spool is probably better. It'd be perfect if you can have a front disk brake system. TC design is at an apex, and new things need to be thought out for the future.

I think what he's trying to say is one ways aren't for everyone or every layout. They are perfect for smoother driving styles, running a stock class, or on a wider more open layout that doesn't require a lot of breaking in the corners.

They don't work so well on tighter tracks that require a lot of breaking in the corner as using heavy braking with a one way will cause the ass end to loss traction much easier than with a solid axle in the front.

can anyone let me know the difference in handling between

1. having both a one-way in the centre and the front...
2. having just a one way in the front
3. having just a one way in the centre and a diff in the front
4 having just a one way in the centre and a spool up front.

I have tried both solid diff in the centre and spool in the front and solid centre and diff in the front.. also tried one way centre and front which I like.. hard to race with if there are cars hitting you.. was thinking of trying just a one-way in the centre or front but I don't know what its changing in the cars handing by having just 1 one-way.

Thanks

Not sure what you're asking.

A one way is meant to uncouple drive from one side of the transmission train to another, be it between motor and a pair of wheels or between a wheel and the other on the opposite side. Therein lies the gain (or the pitfall). Wheels can freewheel offpower so they can follow other trajectories than they would were they conditioned by being tied with a belt to the motor or the other wheels, or with a balldiff to the opposite wheel. In practice this translates to the front wheels being able to follow a tighter line around the corner. Sometimes the line is so tight, the rear wheels just can't follow, so they lose grip and the car spins out.

Conversely, on-power a one way behaves like a spool, so it allows no slip at all whatsoever. Hence the powerful acceleration. So much so, that sometimes you can find your electronics/motor overheating and you have to gear lighter than you would with a diff.
