Thanks linc for doing the crunching... really do appreciate the help!

So...
Yes i do have the 7mm adjustment needed to push the pinion away from the spur due to the larger motor can....
BUT
i do not think that the larger 62t spur you are talking about will work with my ofna spider diff... and OVERDRIVEN, i dont think that 0.5mm will make enough of a difference with y current situation.... I think i did see a 52t somewhere, but i am unsure about that....
But i am worried, that if i use a spur which is too large, it will then hit my top plate on my diff mounts....

Linc, just out of curiousity, will the 56 motor have similar mounting points as the castle motor?

I am now considering turning my motor/diff mount 180 degrees now, and have the motor mounted at the rear and somehow mount the 3rd lipo up front. This would give me more space for a larger motor as i have plenty of space in teh rear.
AND
I wont have any problem clearing my front brake mech. I will just not run rear brakes and i can run what ever pinion size i like and mesh as close as i want.

But i cant work any of this out till my Chassis arrives from GCM....

Linc thanks again!!! i will update this thread when i know more about the space i have to work with....

Im not even sure if the motor will sit right when mounted to the motor mount.... because it will be too fat and hit off the side of the tvps?

You will see what i mean...
