how do You solve the back when cage is in?

[Kislik]

mine will come soon and I see 2 issues. firstly i need somehow cover the metal when rear seats are gone, thats easy by some carpet. The second one is that when rear seats are off there is a hole from the boot to interior what is unlikely. How do You colse it? some CF panel or so?


or just an idea, can the rear seats stay in with cage? not for sitting of course

I wonder if the Raven E46 Cage would fit the CSL :

I think that this rollbar is the best as it does not require welding or anything.

I'll have Wiechers cage which is designed specially for CSL to not touch the side CF panels

Is that a full or half cage, just got mine only rear cage it is a tight fit but a nice bit of kit.

The m3forum cage is clever the way you don't have to drill holes, but should the cage not sit tight to the floor

I don't think it's a problem to drill couple holes, they can be easily covered and hidden when the cage goes out one day

I'm not sure, but in the case you flip the car, the cage will just get pushed against the floor. I don't think it's a big issue.

I really think that this roll bar is very well made, and is a simple bolt-in solution.

I know some search for the holly grail, ie a cage that when removed leaves no witness buuut:

Im no structural engineer, in a roll-over situation would this cage crush and the moving bars be more of a hindrance/danger than a saviour???

The racers / cage experts with more experience than me might be able to qualify this but i wouldn't want to install a cage for appearance purposes only?!

What do you chaps think?

[karbonkid]

Depending on intensions of usage (looks OK for show only), I would not want to rely on a cage for track/ Ring that is attached to the floor with only 1 small bolt on each corners (4x bolts for the entire cage work). I see this as being more dangerous than good. More to the point a 2/ 3mm plate welded is minimal, even for a bolt in IMO.

I can't see it given any structural support to the car, adding stiffness or preventing flex either.

For someone going down this route its clear that you don't want to weld/ drill into the bodywork but theres no real substitute.
