Going to take the plunge and convert my XB8EC

[jhautz]

I should probably be a little more clear about this. The buggy I was running was a Cen Matrix with the cen truggy dif gears in it. Cen uses some very strange gear ratios in the difs so the pinion gear choice does not translate directly to other buggies. The xray buggy(40/12) also uses dif gearing a little off from the standard (43/13).

By my calculations the pinion that will give you the equivilant overall gear ratio to what I ran would be somewhere between 16 and 17. Go wth the 16T pinion if you want to be on the temp safe side.

That should get you approx 40-45mph.

Other than that, I think the setup you have listed will make you very happy. They dont get better than that.

BWT: I just converted a xb8 myself and am really loving it. great buggys!
