FYI - What Losi labels as +1 are actually 2mm wider per side. I ran these for a while and it really calmed the car down and took the edgyness out of it. Now I'm running Xray 1mm hubs in the front and the Losi hubs in the rear. This gives a little more steering while maintaining the stability I prefer.
Air - I think you were discussing the 1/2 inch offset hubs.
Take care,
