Is this cage legal
Discussion
Could anyone tell me if the front legs of this cage are MSA legal or would it fail scrutineering due to the bend?

I agree, but best bet is to ask a scrutineer.
A junior scrute queried mine - tubes too narrow (car's from '71) but asked the Chief.
Who consulted his enormous experience and memory, allowed me to race, and then referred me to the MSA's Technical Dept.with a specific supplier as his suggestion.
I now have a certificate from the MSA, documenting the type and supplier of my roll cage!
Wasn't cheap, but no junior or officious scrute can fault me now!

From the MSA BB 2017: Section 1.3.1
Main, Front and Lateral Rollbars. These frames
or hoops must be made in one piece without joints.
Their construction must be smooth and even, without
ripples or cracks. The vertical part of the main rollbar
must be as straight as possible and as close as
possible to the interior contour of the bodyshell. The
front leg of the front rollbar or a lateral rollbar must be
straight, or if it is not possible, must follow the
windscreen pillars and have only one bend unless a
windscreen pillar reinforcement [1.3.5(e)] is fitted.
I would say the pic falls foul of the one bend rule.
I'm going to say that's not proper foam either (although not technically a fail I believe but can be pulled up by the officious scrutineers).
As above, the best thing is to contact a scrutineer from the back of the BB and see what they say.

Loving the carbon fiber addition to the cage - I might do that

what engine size is your car. If sub 2.0 then there is no mandatory requirement for a front section to your roll cage - it is recommended only. therefore what you have is legal as it is not required.
However you will need to make sure that the footings for it are boxed and welded properly - I can't tell from that picture.
blue book p160,
1.6.1 production cars, touring cars, sports cars upto 2000cc - basic roll bar/cage complying with K1 or K2. See page 179, drawing 1 and 2.

But be careful, some series (like Combe Saloons) mandate a full cage compiling with the MSA regs..However you will need to make sure that the footings for it are boxed and welded properly - I can't tell from that picture.

PS That soft foam cladding (!) for the cage _IS_ illegal, if the events you enter require FIA homologated padding.
FIA 'padding' is hard, but impact absorbent, shiney surface, http://www.demon-tweeks.co.uk/Product.do?method=vi...

I think if the leg went straight to the bend above the dash it would be legal - the second bend rules it out.
I understand why the lower leg would be bent here and there to allow the original dash not to be cut but the upper bend must be close to 90 degrees and cannot surely be very robust.
To me it just does not look like it would do the job
