Jacking plate question

Ive been club racing of several years now, and have been to embrassed to ask this question and unless im blind I cant find it anywhere in the GCR. But is it illegal to weld plates on the bottom side of the car where the forward cage is welded to the floor? Like most guys I jack my car up from side to side but it is playing hell on the mounting plates. When I first started out crewing for people with IT cars no one had them but I always assumed no one had them!
 
Well, nothing says that you can add plates to the bottom of the car for any reason that I know of.

I've added bars to cages for jacking plates. As long as the plate doesn't attach to the body or floorboard you're fine. You run the risk of a lot of people telling you that you've got too many attachment points, but as long as you can prove that they're not attached...

Curtis, how could you even ask such a qustion - isn't it obvious that jacking plates would be contrary to the class philosophy? Now, if you want to shoehorn a Motec engine management computer into your ECU box, that's OK. Does that clear things up?

But since it doesn't say you can......

This is something that I would like to see amended, make an allowance to stiffen a particular area on each side of the car, not an attachment point of the cage, simply to give the jack a place to land w/o crushing frame rails, rocker panels, fuel lines etc.

Last season I watched 3 different people in one day crunch something while trying to lift their cars. Smart guys who have been racing a while who were in a hurry. Frustrating.

Is it worth the hassle of asking the CB to look at this and make a change?
 
IM planing on adding them similiar to the picture above. If anyone has a problem ill break out the port-a-band and cut them off. But to me its a safety issue anyway. I bulit my cage w/o boxed in plates (never saw them until i completed mine) and it plays hell on that area, so im going to have to do somthing.

Like I said, if you can prove that it's not attached to the floorpan or rocker in any way shape of form, they can protest all they want. It's not an attachment point and extra cage tubes are allowed and even encouraged to touch the chassis in as many places as possible (yes, I'll be thumbing through the GCR tonight to find the exact quote).
 
17.1.4.1.10.5.
Any number of additional reinforcing bars are permitted within the structure of the cage, bla, bla, bla.........

I would conclude that the "Scott bar" is a "reinforcing bar" that is a non attached reinforcing the floor so it don't cave in.

What makes this interesting is "within the structure".
