Hi I am a beginner, I hear someone saying that if the track small and with tight corner we should use front diff. If I am wrong please correct me. Thanks.

Yes a one way will give you more steering, I myself have never liked a front diff, too much push. You do have to be careful on the brakes with a one way though.

If your track has tight corners or spots where you need to brake hard to make the corners, then the diff will be better. The brakes don't work on the front wheels with a one way. If it's open and you can let off and coast into the turns then the one way is best.

Since you guys are on the subject, I have a question for you, have any of you guys ever tried a oneway and a solid rear diff on short tracks with flowing corners that a oneway works well on. I know the 1/8 cars use them, just wondering about 10th, seems nobody in my area has even tried it. Thanks BB

I tried it a couple of times with the Yokomo. Found it very slow even on short flowing tracks with a TC Shell. Stick on a Lola shell however and its a different story.

With a TC Shell I prefered running solid front and rear. Drives great and once set up right the car will run on rails and react as you want it (Fast in and out of the corners).

One-way is the stuff for the right situations.

A solid diff isn't a gear diff.
It's a solid spool (solid axle) that doesn't have any diff action.

i would imagine a spool would have a lot of fron traction and steering-but i would also guess that it eats tires-am i right?

It really depends on the surface you are running on. At our track the tire wear is really minimal regardless whether it is a spool, diff or one-way. 4 qualifiers and a 30min final with max 1.5mm wear on the outside rear using 40 shore front and 37 rear.

on a track that is more abrasive it will give slightly more tire wear but not excessive enough not to bother with it.

let me just get to my question-i dont do any organized racing(not yet),mostly just bashing on asphault lots. its pretty smooth,no dust or sand-but my car pushes alot and i wanted more aggressive steering and front traction-what is the best bet-stock diffs,one way,spool or some other combination?

Possibly none of these will be the problem. Have you tried playing with different springs, tire shores etc or adjusting the camber, caster and toe on the suspension geometry. These will have a far bigger effect than changing the front diff etc...

Using silicone diff oils in your front diff would also help a lot. This gives you somthing in between a free diff and a oneway/spool in the front. It would probably help if you told us what car you have and how its currently set up.
