Hello all.

ive decided to remove the rear seat base/overhang and the bins. Cut most of it out, but i am unsure how far back i can cut the seat. Looking at the healboard ? panel its shape, can i cut the seat back so its flush with the shape or should i just line it off and make it straight before that?

Pics would be good if anyone has them.

Cheers
Jordie

i have never done this but what i have seen before on tmf is cut it off leaving about a inch sticking out

then hammer down this inch bit and weld to the up right bit of the heal board

[Jordie]

Ah i see. thats great thanks.

There is an article in this months Mini Magazine showing them cutting the bins out to fit a cage,might be of use to you.pics as well.

[Jordie]

The bins are out, just wasnt sure how far back to cut the seat base, didnt want it to come apart from the healboard panel

What have you added to replace the triangulation of the B pillars to the floor that is provided by the bins and is pretty important for the strength of the shell? Do you have a cage?

[Jordie]

Yes i have a rollcage

up to the heel board is fine.. always done it to my race cars and have just cut my road car seat out...



its when you cut it out you see how many holes you have in your heel board

[robson]

when i cut it, i left the welds in tact, didnt bother folding it down and welding it back

[timbo]

Could you cut back like this with just a rear cage or wouldn't it be structurally sound?

[Jordie]

As far as i generally read its not very structural.

Ive cut back most of it, only found 1 hole in the healboard. Wasnt there 6months ago when i did the rear subframe change.

It's not good with any cage unless the top of the hoop is gusseted to the B pillars. A rear cage should be OK so long as this is done. The MOT inspector may not see it like that though.

So long as you leave enough of a flange to stop the spot welds tearing under load, the original welds will be fine. The cut edge would be a bit dangerous though. This join gets quite a lot of abuse so you need a good strong weld.
