I keep going over my rules for 2004 and see a lack of definition for the no wall class. If I read the rules it states that I can sound dampen as much as I want behind the b pillar, unless I over looked it there is no designation made for no wall that is different from any other SS class. So my question is this. Am I allowed to do whatever I want behind the b pillar as long as my enclosure is below the window line? The no cutting of the floor is understood as that is made clear in the rules. Also do rear windows in vans need to open or can they be sealed? It is behind the b pillar and normal use (sight) is not an issue.

quote:Super Street Division Passenger Compartment Restrictions
3-10a Modifications to the passenger compartment from the B-Pillar forward are prohibited.
Additional Guidelines:
· The OEM headliner (or an equivalent replacement) must remain in place for those areas in front of the B-Pillar.
· The OEM door panels (or an equivalent replacement) must remain in place for those areas in front of the B-Pillar.
· The OEM carpeting (or an equivalent replacement) must remain in place for those areas in front of the B-Pillar.
· Sound damping materials may be used to reduce vibration when installed in accordance with the manufacturer’s recommended installation instructions. For those areas located in front of the B-Pillars, the maximum total thickness of sound damping material applied at a given point may not exceed 5/32 inch (4mm). The sound damping application may consist of mat-type material, spray-on material, or a combination of the two. A maximum of 2 layers of mat-type material may be used in any application, even if the total thickness of the sound damping material(s) is less than 5/32 inch (4mm). For those areas located behind the B-Pillars, an unlimited amount of sound damping material(s) may be used.
· Expanding foam may be used sparingly in front of the B-Pillars to seal small openings or reduce vibration, but may not be used to fill voids or other large cavities (such as the dashboard or doors). An unlimited amount of expanding foam may be used behind the B-Pillars.
