cage adjustamfacation, will it pass tech?

I don't see how that could pass tech.  There is a requirement for a diagonal on the main hoop.

Come to think of it, there's also a requirement for rear stays on the main hoop with no bends in them.

Also, there is no roll bar padding.

No way this is gonna fly without some sort of waiver from Jay or Nick.  I wouldn't expect that waivering safety equipment is something they would be too eager to do.

Would it be safe?  Well... there are reasons for the cage requirements.

to continue the crapulance:

this almost wants me to break out the paint program and have some FUN!!! 

When in doubt defer to Professional cage builders.....print out a copy of the rules & take them with out to the cage builder.....let them read it and give them the related car info (weight) they need to design a proper cage

I don't like it-    If your drivers need the main hoop that far back, they will be sitting within the first hoop, and if they're that tall, they will be hitting that first hoop with their helmet. 

   If I were inspecting a cage built with your modifications, I'd fail it.   There are too many possible failure points and non braced members. it also contradicts the 'single continuous piece' rule   If the rear hoop is your main hoop then the door bars aren't continuous, same with your halo bar, etc..   You can't say the first hoop is the main hoop for the door bars and ignore it for the diagonal and the rear stays. You've got to choose one.

    As a cage builder, I see it as being easier to move the hoop (rebuild the cage) than to add a second hoop.   

   You can also try a harness bar that has setback so the seat can move rearward farther.  We use a harness bar that is bent at the main hoop and where it attaches to the diagonal..  you can get up to 6" this way and not have to do major surgery to your cage.   In the same process move the diagonal to a more upright angle, moving the upper attachment point two or three inches to the right, giving more room for the drivers.....

that was my original though, but this flash of brilliance came to me and I thought I would see if it would work.  As it is now, the seat stopped at the front of the hoop.  I was thinking that if I could get them under the hoop, that would give us the leg room we need.

I was thinking something like this:

green is the diagnal and harness bar, red is the rear down bars, blue is thecross ties for the rear.

This is probably a better solution than the double-decker main hoop theory, but Evil Genius' original concern that if a driver is tall enough to be restricted by the position of the main hoop, then allowing him to move further back will just put his head underneath/alongside the main hoop. Ideally, the main hoop is behind--but not too FAR behind--the driver's head, providing protection in a rollover but not presenting a "bonking" risk due to insufficient bar-to-helmet clearance.

If you want to play it safe, both in terms of actual safety and the chances of passing tech, you'll need to start over. Otherwise, you're decreasing your odds all around.

the problem wasn't so much the height, as it was the seat didn't slide back far enough because of the diagonal.  I am going to try the curved harness bar and see what sort of leg room that gives me (i.e seat slide-backedness).  For the cost of a new cage, the guys and suck it up with a little less leg room, since that is the only real bitch. 

I'll probably end up redoing it all when I try for the uber pimp center seat relocation-o-rama this summer.

finally working on it, since the race, is like, saturady or something ....

some new and improved pics, going to bend some tube today for a harness bar.

the before, hendered the leg room:

cut out the bars, where the seat needs to be:

in order to get the seat to sit flush, because I bought the fat boy friendly Corbeau
