Roll Cage while still keeping OEM softtop
#145
The car club that I have been with for several years are increasing the effort/complexity of entering my S2000 [and many other convertibles] in to Time-trial events. The crux of our situation was spurred by a caterham [nee -lotus7] showing up for Time-trials event and the question of how strong/WEAK a windshield frame is on a few cars that competed lately. The windshield frame has become a crucial component in defining the roll-over structure in our car club in So-Cal. The club is now trying to shift any burden/question of windshield frame integrity on to convertible owners, regardless of how robust the roll-bar is on same convertibles. WHY should Windshield frames matter?
Well the thinking is that the previously mentioned broomstick metric/test should apply to an imaginary line from the top of our convertible shock-tower to the top of the aftermarket roll-bar for most convertibles . . . unless we can substantially [with creditable documentation?] that the windshield frame is the equal of the roll-bar integrity.
Furthermore, since the broomstick [along the now SLOPING imaginary line] will intersect with 80 or 90% of our convertible driver's heads, they mostly will Fail the test.
Ultimately, I am writing to ask if there are others who solved this same problem
OR
If anyone can help [with creditable and public documentation] help us substantiate how robust the windshield frame is on my MY2004 car. Thanks for reading this through.

"S2000 COCKPIT SAFETY SYSTEMS
...
Even though open-topped cars are exempted, the S2000 meets the federal standard for occupant protection in a rollover accident. The driver's and passenger's roll bars are made of 1.5-inch diameter high-strength steel pipe with a .080-inch wall thickness, and tie directly into the frame. Additional protection is provided by reinforced door pillars, windshield posts and the windshield frame."

This part was especially good to know "the S2000 meets the federal standard for occupant protection in a rollover"
I can only hope that car clubs are impressed with that statement from Honda.
