The height of the tire you are going to use has an effect on what offset is needed. If you are going to run a taller than stock a 3+2 would be acceptable ,if you are running a short mx tire a 4+1 would be needed. If you are running the oem tire,the oem wheel is best. Honda did not make a mistake with the oem setup.From the factory your tires turn slightly off the centerline of the ball joints, moving it to exactly center isn't necessarily a good thing and moving it further away from center is even worse
