My front bumper has had a split in it for ages, that’s been progressively getting worse. Honestly, it’s impressive that it’s lasted as long as it has, through nearly 10 years of dedicated autocross use.
I found a piece of *cough* scrap sheet metal to make a patch to strengthen the area:
I figured 10 rivets would be a nice, round number. It obviously doesn’t need that under static conditions, but when you hit a cone at 50 mph, more is probably better.
After a couple minutes on the drill press, then belt sander to debur, I positioned it on the bumper to transfer the holes through.
Final positioning before riveting it in place.
And the rivets in. Job done. And just picking up the bumper I can feel that it’s far stronger now, with a lot less flex overall.
