Im looking to get into some gncc style racing and wa wondering if anyone has used there 660 for this and what all I will need. I would like to get every thing done before summer but I want to keep the motor mostly stock and I have a tusk clutch kit on the way. Basically ehat suspension works best r 2"+ a-arms to wide do I need nerfs, tether switch, etc. Any info or opinions r great. Thanks in advance.
