I recently went to a derby. 2nd one I've been to. First one was OK. They wet the shit out of the field and only street tires. So minimal speed.
The one I just went to was insane. Boarder brawl, in Bonners ferry, ID. I only say that, because guys came from all over and there was a $10k purse
These cars were serious. Many had trussed to the moon 14 bolts, crazy wheels, front suspension welded at full droop ect. The amount of damage it took to get them to disable was impressive. I think the last few just got so banana'd that they eventually got stuck on their own belly. Still running.
Instead of watering everything down, they would run a grader between heats and smooth everything out for more speed
Some of these car sounded real fucking heathly too, definitely not a junk yard small block.
Anyway, it looked fun, but also looked painful.
BTW, aren't you supposed to build the cage out of railroad track and #16 rebar?
But really though, instead of bolting it together. Why not weld it all up, then just cut the roof off to remove or install? Is cutting the roof off and welding it back on against the rules?
