Part of the trick with mre overdrive is using it. That means not trueing tires to different sizes but actually creating more front drive. It will give more stability on power and more turn in off power. In low grip this may lead to off throttle oversteer though.

So Julius, do you mean with smaller front and bigger rear tire to maintain 1 : 1 ratio in car that having overdrive tranny did not have an overdrive effect ?

But seriously Julius, wouldn't the front arms be flatter and intersect at a further point = lower roll center? If the front arms are more angled because of using smaller tires and setting the shock springs to get back the ride height, then I would agree with you... But that's not the case with the arms right?

It all depends on the relation between both arms. It is true the intersection will mover further away, but the lower arm gets a flatter angle which will raise the intersect point in the end.

No, this can be the case with all drive configurations. With overdrive at the front the front wheels turn faster than the rear. If using same diameter tires and off throttle, the fronts will want to try and spin the rear wheels slower thus creating more drag at the front end = more weight transfer to the front. This can the lead to oversteer off throttle.

The one way in this case doesn't help because the frnt wheels will be running at a lower rpm than the rears thus effectively engagine the one way all the time.

I never knew that the drag would happen on an overdriven car much less with oneway front ! I know that on 4WD cars there will be a drag but the weight transfer explanation about this and causing oversteer is excellent. Thanks Julius. :nod:

Another spin off question... So using overdriven front from the 21T pulley with equal front and rear tires would give the car somewhat like a drag brake effect? No?

Yes, the one for S710s should start shipping begining 2005 according to the official guys on mytsn forum.

Anyone tried the light black coated alu mid shaft on S710? they are xtremely light and I wonder will it bent on usage?

Am I the only one that do not understand what you are saying or there isn't any answer to your question?

If you don't have even the part number Pyramid then I'm sure what Choco meant about the one in Serpent USA is something else ... ;)
