the less back spacing the wider the stance. I think the wraith axles are a little to wide so i wouldn't get a wheel with less backspacing than the stock wheels. If anything i would want more. However you can only get so much back spacing before you start interfering with the knuckles. Does anybody know the max back spacing you can run on a wraith? Anything less than that would work also. Good luck"thumbsup"
If you want something cheaper than aluminum wheels but keep the track width close to stock get XR-10 beadlocks.
I'm using Mayhem Berg offset wheels and they actually narrowed the width from stock because of the narrow wheel. There's just enough clearance for the steering. I just don't like the super wide look. Just looks goofy to me.
I actually had XR-10 wheels but I messed up and let an axle nut get too loose and ended up stripping the hex. That's how I knew I wanted a narrower track width. I don't know what stock was but right now with the Mayhem Berg offset wheels, I'm at 11 1/8" from outside to outside on the width.Or this...however the stock XR-10 wheels are perfect width for the 2.2 Ripsaws.
