Miata cage, just checking

I'm not an authority other than having just finished welding my own cage kit in a different car, which passed

that cage design looks pretty nice.  I like the custom front spreaders.  the rear down tube spreaders look undersized but I bet they know Lemons rules and you'd 24 square inch versions.  Headroom is tricky on a car that small but they put that bent diagonal in so maybe that's how they addressed that

you're probably aware that their kit costs a fair bit more than competing cage kits, but if it saves your installer time and you like the details, maybe it's worth it

I would ask the seller for pictures of a passing Lemons install, and how many Lemons installs they've had pass tech previously

I bought a cage that is very similar to that as a kit from roll cage components for about 500 dollars less if I remember correctly

I'm going with a custom cage from the rally guy.  Thanks again!

Cage is done!  The builder did a great job! 

If you're in the Denver area and you need a cage you might check out BA Ingenuity LLC.  He did me right!

It has a rear diagonal!  That's just an almost complete picture.  https://imgur.com/a/IEIUptv

A lot more confident now.  As long as the rear down bars land in front of the back of the wheels, you are very likely to pass tech.  The "grinding" on the tubes is likely clean-up with a flap disc (still technically not OK) so less likely to get heat on that.  If the diagonal not touching the harness bar gets you grief, tying it into the rest of the cage at the track is a relatively quick fix.

Thanks again for the feedback. 

The cage builder mentioned the potential for harness slippage.  The seat is going to essentially touch the harness bar so it "shouldn't" be able to slip as the harness holes "should" hold it in place.  That said, we'll take mitigating steps if we find any slipping when we are track testing the car over the winter. 

I'll be emailing John Pagel about one part of the cage - where the rear bars are welded down.  The cage builder pointed out that to avoid the fuel filler neck he had to weld the rear bars a hair further back than is allowed.  He found pics of other Lemons Miatas with the same cage designs so was confident it would pass tech.  I'm sure it'll be fine but I'm a nervous person so will verify with John soon.
