Saw these in Grassroots Motorsports last night. I like the idea of angling them out a bit into the door, for which i have room. Also the fabrication looks clean and I think the bars are stronger the way shown, but if not please pipe up.

Even though you aren't building for wheel-to-wheel racing, with a hillclimb car you still need to be concerned with potential intrusion from trees and big rocks. They don't present the same profile as the front end of a car does though, and I think a bar up high might be more important. Elbow room and chassis stiffness are the next biggest factors in door bar design. I would go with NASCAR style bars on the drivers side and x bars like you pictured on the passenger side. |

We do have another bar coming from the rear hoop (6" down) that intersects with the dash hoop where the (now) elongated hole sits. The purpose of elongating the hole was to make the run forward (to the shock tower) straighter. But I sure agree with your point about hill climbs and for that reason alone I think the NASCAR style bars would be smart. |
