So the 21T has already arrived? Plastic or aluminum?

To prove you Prophet-ness, could you please give us the low down on what the overdrive will give us? We would be most grateful, oh great wise Prophet :yes:

Can I give wrong info? muhahaha

To get the same 1:1 overdrive on the front and rear, you need to run a 4 mm split i.e. front tires 4 mm smaller than rear tires.

We do not even have the part number yet for 21T

I predict the part number to be 802171.

Ok that's the wrong information, so what's the right info?

At the moment we need a 1mm split for 1:1, you mean with the 21T we would need 4mm split? So what is the advantage of the 21T?

You want the wrong or right info?

I guess for those who still get more wear in the rear would benefit as the split would stay the same almost throughout since the front tires will rotate more turns than the rear tires. More rotation in the front tires means more wear and this somehow will translate to even front and rear wear rate.

Front side of the car would get an even lower RC due to the front sitting lower because of smaller tires while maintaining same ride height.

And lastly, you get to use a bigger rear tire to achieve the required tire rollout / top speed for a particular track while still being able to use smaller tires in the front for better handling. Not forgetting the times when you need the tires to be big in the rear because of excessive wear and rear ride height clearance, you would still be able to use "smaller" front tires.

In reality the front roll center goes up when using smaller tires. You'll need to set the springs to get the ride height back and that moves the suspension arms in a position that raises the roll center. It's a small change though, as the roll center doesn't move a lot with suspension movement.

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.

Aiks ! The Master has detected an error.

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?

Yeah I agree with you there Julius but 4 mm overdrive seems like a lot if both front and rear tires are equal diameter. No?

Is that the case only if not using a one-way?

I think you are only looking at the upper arm, definitely it would be straighter but the outer part of the lower arm will now be lower due to smaller diameter wheels which would then raise the RC but I dont think is that much anyway.
