I think 98% of the caged cars on here have 6x6 plates at all rollbar/rollcage mounting points, as well as mine.

It's not directly welded to the subframes.

we plan to tie our 10 point into the subframes by going through the floor and straight to the umi round subframes. That is the plan at the moment.

this is a matter of rule interpretation...

by the rulebook, unibody cars must be welded to 6x6 plates on the floor...so even if you go thru the floor to a subframe, you may still need a plate there too.

on full framed cars they go to the frame...but a unibody for SFCs is still not full-framed...

you could just run some round bar with a plate to the floor pan under the cage mounting area. the best advice i heard is to have your mounting plate extend through two axises if i'm terming that correctly. like in the pic above how its on the flat top part of what i believe is the torsion box (i'm really not good with terminology ) and then extends down the backside of it.

I've read the 25.5 SFI Spec. I didn't see anything mentioned about subframes. you must be doing a 25.2 or 25.3.

look at bars 2A and 2B on the 25.5

By design they are supposed to ultimately tie into the subframes

even then, the rocker bars run in between the OEM subframes which tie everything together.

You're rocker bars are above the floorboard, right?

Are 2A and 2B needed if using the OEM firewall and trans tunnel?

We always just go to the 6x6 plates welded to the floor. Anything more than that is overkill.
