Let's not be naive here, this is the reason the 2.6" class got out of hand. This is not a "street" class, it might have been, but it won't stay that way. I recall someone saying last year that a 3" turbine would be the largest wheel ever run in this class, and that has been proven wrong this early on. Rules need to be made for what this class will be, not what it is now, that again was the downfall of the 2.6" class.
Receiver hitch, no bars extending hitch length nor from tube to axle.
Allow hanging weight, no weight boxes.
Allow dual CP3's, no RSV governor.
Single 35" tire on 10" rim.
Turbo rule should work, may change the rule to say "no tapered covers or wheels". If you are thinking now that this class won't have driveline breakage, therefore there will be no issue allowing 35" duals, think again.
