a couple of TM4 Queries...
 

Could some one please tell me...

1. the reason for the 14mm hex front wheels. what benefit do they offer over 12mm hexes?

2. why would one choose to run the TM4 with a centre diff rather than a slipper? With the diff in place, you effectively have no slipper, and rely on some wheelspin?

Thank you
Tim

1. Nothing other than personal preference. The new 12mm allow you to alter track width by using different hexes.

2. The centre diff controls the output of power between the front and rear wheels, therefore it's better in low traction conditions. In low traction I run the centre diff with 150k oil. As the back of the car spins up, more power is transferred to the front, making the car more stable and easier to drive.

Great, thanks Allan.
