Default spool or diff for silvercan(stock) racing

Hi there.
Generally speaking...
Is a front spool or diff for better for silvercan(stock) racing??
Im guessing , given the low power, a spool is no advantage, and may make the cornering slower, as the outside tire will dragging ???
(I have a Xray 2008)

Cheers

TC3 I used for stock racing has a one way in the front, just have to be very easy on the brakes or it will spin out easy. My modified TC3 has standard front diff in it.

For your local tracks i would use one way, but as was said you just have to be soft on the breaks, and smart where you use them. If you were to run on a low grip surface, i would swap to a diff.

A spool is going to give you accelerating comming out of the corner. But the trade off is less streering in mid corner. You would have to setup the car to compensate.

I think spool is more consistent and easy to drive. Should be better in most cases even in a 540 motor class.

Does this mean slower on sweeping corners??
The corners seem to be the one place to gain an edge in stock, straight line speeds are all more or less the same.

A spool isn't going to effect the car's handling in a sweeper as much as it will in a tight turn. More toe-out in the front should help in corner entery.

Does this mean a spool will be quicker than a spool in tight turns ??
Plenty of tight corners at the local track

Or is the spool better on exiting the corner ??

What track are you racing at? Down here at Ruapuna, the fastest guy in the club was running a spool, but our track is a beast. Most of us ran one-way's, but weren't as fast as hium.
If it's tight i'd say a diff, as a spool will generally give a bit of under-steer and compesnating with toe-out will slow you down a tad.
A one-way is the fastest, but you can't brake which sucks on small tracks.

If you're runing a tight track, a spool might work out best, because you have full use of brakes. One-ways will have to rely on the motor's natural drag brake. But it all comes down to personal preference. I like spools, because I like to know I have brakes when I need it. And to have that instant acceleration comming out of the corner. I might try a front One-Way some time, but I'm in no hurry.

At Albiny from memory you only touch the breaks 2-3 times a lap, and the heaviest breaking point can easily be done in a straight line (hairpin)
I know speedi ran a spool in Ruapuna, but im sure if you ask him he will recommend a one way for albiny

A spool is always a sensible and fast choice at any track. It will also be good when you decide to move up a class as you will already have the correct set up for more power.

A one way will probably give you bad habbits that will really show up once you move up to something more powerful. It will also be really inconsistant and very dependent on grip levels.

A ball diff will work if done up tight almost like a spool.

Im running at Albany. The cornering seems good with a spool, I just wonder if a diff would be better , since I have one to spare
I dont think I have the skills (& concentration) for a oneway.
Dont have a one-way, would be out of my budget for the Xray anyway $$$$
Cheers

Looks like Im sticking with the spool for now then.

Since you have a spool and a diff, the best way to know is to try it out and see which one you feel better (in terms of consistency), or which one gives you better lap time.

Personally, I would pick a 1-way because its the most efficient and has the best cornering ability out of the 3. In stock racing (especially silvercan), its all about the ability to carry as much corner speed as you can since the power of a silvercan is very limited.

1-way is not that difficult to drive, its just different.

It really depends on your driving style and how you're car is set-up.

In regards to one-way and brakes, if you're running silver can its not an issue. You won't be going fast enough with the silver can to require any braking through the turns. Back in the old days of 27turn brushed stock, hardly anyone ever needed to use brake. Nowadays with 17.5 BL you really do need brake, hence the need for the spool to keep the speed under control.

Give the oneway a try and see how it suits you. If you set your car up right, you'll find yourself cornering faster never needing to brake at all.
