When a roll cage bar/chassis tube goes through a firewall, what do you do? Do you cut the hole close and then weld around it, use seam sealer, just live with a small gap? I am trying to decide what to do with bars connecting the cage to the front and rear suspension points. Thanks, John |

Thanks for all the great replies. I am looking at what the original builders of my IMSA car did and it looks very rough. They cut way oversize holes and then riveted aluminum or very thin sheet metal around it. I am trying to decide if I should leave it "original" or make it a little neater and more functional. They did not seem overly concerned about holes between the passenger and engine or front trunk area. I'll post some pictures tonight. John |
