Looking for some advice… im installing a MiataCage in my 2000 and in the instructions it is noted that one may notch out some of the hardtop interior plastic where the top main hoop corners hit the hardtop so as to get the main hoop to fit tighter. The instructions also note that this may or may not be legal depending on how you read the rules (Paraphrasing here). Any feelings on this out there… im not seeing any rules that specifically allow this… Not sure if a lot of cars have done this…. Im installing the package shelf version and am leaning towards doing it bc the farther that bar is from my head the better but im stilll on the fence. Thanks for the feedback!
MiataCage Main Hoop install

Interested in this...just installed a miatacage in a friends miata, and we notched the top to get the main hoop tighter to the roof. Wasn't worried about rules because it is being built primarily as a champcar.
However-I am about to begin a SM build, and would like to notch the top on it for the same reasons Carlos is mentioning. I really can't afford to get a custom cage built, the miatacage is the best option, but IMO it requires cutting the hard top.
I will most likely do it anyways, it will be unfortunate to get DQ'd for something like that.
I would cite this rule (from NASA CCR), but we don't have sheetmetal there, just fiberglass.
15.6.16 Tube Structure Design / Body
Tubes may touch the body in any place (not to violate CCR section #15.6.20 Inspection), but shall not be attached anywhere except as permitted by CCR Section #15.6.11.A Rear Braces - Exceptions. No deformation of the interior body panels is permitted, except that the horizontal part of the sheet metal (next to the driver’s and/or passenger’s head) between the top of the “B” pillar and the top of the “A” pillar, may be pushed in to accommodate the roll cage. The intent of this permitted deformation is strictly to allow for more headroom for the driver and/or passenger.
