Does anybody anywhere know where to find the torsional rigidity of the 914 with the roof off vs. roof on vs. steel roof (916) ?
Thanks in advance. |

A bolt down metal top would make a big difference as it completes the "box" just like in a FRC Corvette or Supra Targa.
Bracing the longs is a band-aid for not having a solid roof structure. The longs flex because there is no top to the "box". An A pillar to roll hoop brace setup would probably do more and weigh less. The trick would be making a fiberglass top with a metal structure and a way to actually bolt it on. Of course a full cage takes care of the issue all together but is not feasible for street cars. |
