a-arm length

I am going to widen my son's kfx400. I am looking for advise on weather to get +2 or +3. He races motocross with it.

+2 will be the best and then adjust with offset rims

Thanks. Appreciate the help.

If he races motocross why not get +3's and use 4+1 offset wheels? must work good since just about every pro runs that setup.

That is exactly what I ended up doing. Thanks for the advice.
