Extra Width
When I ordered SC wheels.for the ET410, I got some Pro-Lines that were Slash 4x4 offset. If person wants a wee bit more width, get SC wheels made for the front of a Slash. Those wheels should have 2.3mm more offset than the rear Slash 4x4 wheels. Add the +1mm Tekno TKR1654X – 12mm Aluminum Hex Adapters, and you should have 6.6mm of extra width (3.3mm each side).
