1. No Mantas (duh)
2. You gotta play at least a couple times a week. If you have a conflict with this, talk to me and maybe we can work something out.
3.  Some hacking is allowed, but there are limits: 
Basically, hacking is fine as long as you're not doing it just to give yourself 
an unfair advantage.
a.  defenses- the limit is 200 lbs for armor and chassis combined, 
and no fireproofing
b.  turrets- it's ok if you wanna put a turret where it doesnt belong, 
but no more than 1 per vehicle (except tank)
c.  performance- hacking engine, traction, whatever is fine, 
just don't overdo it, for instance 0-100mph instantly is a little much
d.  appearance- no restrictions for paint, wheels, and body hacks
