Roof Panel Replacement - SM AutoX
I'm looking for some clarification for the SCCA Solo rules and roof replacements. I have a 2003 GSR with a sunroof that I autocross in SM and want to replace the roof with a non-sunroof panel but I'm not sure whats legal. I have read the rules and think I have them straight but was wondering if others have been through this. The rules state:
16.1
N. Removable OE hardtops, T-tops, targa tops, sunroofs, moonroofs, and similar roof-mounted panels may be removed/replaced with alternate panels provided that the area of interface is limited to the original perimeter of the t-top, sunroof, etc. or utilizes the OE panel mount points, and that the contour of any replacement panel surface does not vary from the contour of the part being replaced by more than 1” (25.4 mm) in any direction. The material used to construct the alternate panel and the method used to attach it to the interface is unrestricted. Any actuation mechanism and the associated wiring, if any, may be removed. Vehicles utilizing alternate (non-OE) hardtops will be considered as open cars in regard to Section 3.3.1.
I would really like to put a carbon fiber roof or the RS/MR aluminum roof but I am not sure of the interpretation of panel and if they are referring to just the glass piece or the whole roof body panel.

What further confuses me is that in street prepared the rule is this:
15.2
O. Sunroof-equipped cars may be converted to a solid-roof configuration provided a model without a sunroof is listed on the same line in Appendix A.
Appendix A lists all years Evo 2003-2007 (including models with aluminum roofs) and because SM inherits all allowances from SP doesn't this mean it is legal to change to the aluminum roof?

It would seem to me that your sunroof is not "removable," so the SM rule is irrelevant. Under the SP rule, you can convert your roof to another OEM configuration, like a Mitsu aluminum roof. I don't think a CF roof would be legal on an Evo. By contrast, on my SM t-top Camaro, I could replace the t-tops with CF pieces though, provided they work with the stock attachment points, etc.

I guess the safest thing to do would be the OE aluminum roof but what does a full conversion entail. I would guess the non-sunroof headliner, but is there anything else?

Replacing the roof with CF is definitely not legal in SM. There's nothing that says you can do it explicitly, so you should assume that you can't. Replacing door or glass is also not legal.
The JDM bumper itself is legal; however, the fact that you have to modify the rear crash beam for it to fit is questionably legal. IMO, if you can make the necessary modifications by only removing < 1lb of material from the crash beam, then it's fair game. I've yet to see anyone demonstrate this though. I don't care enough to be a guinea pig.
