Check out AKA racing and their line of 8th scale pre-mounts.  I run these on my truggy (RC8TE) and i love them.  I've also had several other customers with the Monsoon and the Avalanche to try other wheels.  I have found that the 1/2 offset works best with proline wheels.  I have had the standard ones hit on the spokes.

They are slightly taller than stock, but the footprint is narrower.
