Also, Custom Cages won't do the fitted price advertised to put the mk4 cage into an A/S3, because it's not designed for it and would perhaps need alternations. they want the full whack £1800+ to put one in an A3.
i understand more bars mean a stiffer cage, but surely a weld in cage with gussets to the car would be stiffer than a bolt in cage with more bars?
one thing that test guy that i spoke too once said is you shouldn't gusset a bolt in cage to the shell
I'd definitely disagree on that one.
The box feet on mine at the sills are identical to those you'd install a weld in cage on, simply the legs have plates on the ends, and those plates bolt to the feet.
If I ran a mig welder around the feet of mine (Which I intend to do at some point), then I can't see how it becomes any different to a weld in cage at all really.
Obviously we'd all like a full weld in multi point if we won the lottery though
So would welding the feet to the box plates be ok for MSA rules as from next year I will doing hill climbs in my s3
So if you welded in a Fia bolt in cage would it it be ok for MSA or is that a grey area ? Not that I'm going to do time attack only sprinting and hill climbs but yet to do a hill climb as I broke my evo for sparesI guess it depends on what rules you're working to.Mine is FIA compliant as per this cert:But not MSA compliant being bolt in I believe. I've been told that to be MSA compliant I'd have to weld my harness bar into place not on the 12.9 grade bolts it's on currently) and weld the feet in permanently.How true this is I'm not sure as I have no need to look into it further, but I have no reason to doubt it.Sam, the cage you posted is gorgeous, but you're looking at an easy £2k+ to buy and install, vs under 1k for a good bolt in.It depends what you're after, roll over protection with some increased chassis stiffness, or the last line in top level race car chassis prep. One costs double the other, pick which one best suits your requirements
