ubrben has a lot of promise if they can keep it on the circuit!
1 - Mechanical trail is the distance between the geometrical centre of the contact patch and the intersection of the steering axis with the ground.

2 - The pneumatic trail is the self aligning torque divided by the lateral force - i.e. it is the distance between the geometrical centre of the CP and where the force is actually centred.

To calculate the torque about the steering axis you add the mechanical and pnuematic trail figures together and multiply by the lateral force.
