As Zetaboostboy says it's mainly to add even more structural support, they're pretty much standard fitment on any rally car. Usually cost an arm and a leg so I bought the dies instead, even made a sheet metal roller today to roll the metal into shape.


Anyway the next step I was really not looking forward too which is fitting the first 4 of the 6 firewall tubes, for anyone else thinking about it you basically need to cut 4 big holes in the firewall so that once the cage is tacked together you can ratchet strap it closer so you can do the reverse sides, it city ally went really well, alot better than I thought it would, had to remake both horizontal bars though as the ones Custom Cages sent had been trimmed wrong on the ends.
