This should help you:

http://www.customcages.co.uk/Rollcage/L ... Multipoint

We dont put the front struts in as they do, we relocate the fuse box and go to the centre of the turret.

Keep us updated

Make sure you weld drop the cage to weld the front hoops to the main hoop. I doubt you can get a weld all the way round by keeping it in place judging by the pictures.

Iv been thinking about this.... What's the best option for dropping the cage? By cutting holes in the floor or by cutting the legs of the hoop and building the feet up to compensate?

Thanks

I fitted a custom cages multipoint to a mk1 clio, was much more comprehensive than the e30 which is mental as it is, some of the places we had to weld were near on impossible but provided things are done in the right order they can be done. Best bet is to tack it, use a holesaw in the floor then weld it back up. alternatively when we did an e36 a couple of years ago, we used a small tig torch with a mechanics mirror. All fun and games! :mad:

Hmmm this sounds like a right old job but I want to take the challenge. It just may take a while. I'll update the pictures as I go. I even brought myself a new welding mask for it haha.

As said drop it through the floor in the fitting kit you get from CC you should have plates to go over the holes which are welded under the legs where they meet the floor. Then be sure to seal from under the car.

Have you removed the fuel tank? if so you will want to as you weld right around it.

as others said, you need to cut holes in the floor. I cut mine as slot, you can drop the cage much firther down this way.
Add some plates under the tube when lifted back up and weld plate to car and tube to plate.

that's the best picture I have at the moment

Thanks for the pics ;)
Well uv taken pics of what I have done but can't put them up until I get back home.
I have cut holes in the floor and the cage nicely drops down but for the plates that CC give, I can't see how thes will fit under the 'A' pillar tubes? I'll put a pics up of them too.

Thanks
Ben

right iv managed to get the pictures up of the holes in the floor to reveal the top of the cage.....
im sure custom cages have sent me the wrong roof bar because it doesnt seem right but iv emailed them and im awaiting a reply with a picture.

these are pictures of the floor plates for the bottom of the 'A' pillars but im not sure how i would use them?

The roof bars are cut too long on purpose, we had to shave around 2 inches off when we did the clio, the foot plates will also need trimming, the step in the plate is to make up for the step in the floor.

Wait till you start putting the rest of the bars in, the profiling is somtimes so shocking that if you didnt know any better you would think they had sent you two halves of different cages

Well that's the thing you see.. The roof bar seems too short to reach both corners of the cage?
And the floor plates for the 'A' pillars will need basically cutting in half because the step in the floor is half the size of the plate itself?

did you cut holes front AND back???? You only need to cut the fronts and tilt the cage forward IMO.

My front plates are just with ONE flange which went up against the sill and was pushed in by sliding it along the sill. I had kinked a small diagonal section of the bottom face of the plate to fit into the recess in the floor.

On the rear B-pillar base Matt from ETA (who fitted most of the cage BTW) has extended the flat face in front of the seat base to form a box on which the tube was welded.

I have more pictures on my other computer, just need to load them up.

Ahh I see. Well cutting rear holes as well has made it a whole lot easier to weld that's my excuse :mad:

I think if you could get some pictures up that would be great :wink:
I have dicidied against moving the rear shock towers in as it's loads of work so now I can start the rear section woooo

Ok here some more pictures
can you see the little "box" under the B-pillar tube?

I have the boot brace prepared to tie the diff into the cage but decided against it because of the noise.Before I had the trailer I used to drive to the Nuerburgring.

Ahh that's wicked thanks alot. Gives me abit of a better idea on my cage.
Looks like a awesome cage you have there.
Is it worth runing a bead of weld around the rear shock towers?

Mine needed welding because they fell out basically. At least at one side.
Once you start scraping the underseal off you can meet all sorts of horrors!!!!

a small update on the cage.
i managed to shorten and profile the roof bar so thats now in and iv started on the rear of the cage just to makesure everythings in the right order, way round and in the right place.
here are some pics and luckly for me my rear shock towers are in real good nick but i may just pop a weld in places just to help me sleep at night...

Just a quick note to point out, if you don't already have it figured, that if you form a box under the cage feet, there must be a flat plate between the 'box' and the floor, extending beyond the box, if you see what I mean.
If you don't have this, you risk getting pulled up by the scrutineers if you are going to compete in any MSA type event.
I'll trawl through the blue book and post up a link if I can find the relevant section.
Kim

Edit:
This is the bit in question http://www.msauk.org/uploadedfiles/msa_ ... Safety.pdf
It's drawing # 18 right near the bottom. It's not very clear and shows a bolt in cage, but shows a requirement for a 'spreader' plate under the raised box section.

look carefully at the edges of the SR panel. you will see the spot welds holding the second panel into the outer panel. carefully grind the welds down and then lever the inner panel off, its bonded in with sticky gunk, i heated it first to loosen it off.

what the man said! Quite a bit of weight reduction IMHO

Did you remove the sunroof "tray" in the roof?

Yep I got rid of the sunroof tray and it was a right arse as well. I'll have a look tonight and report.

Matt from ETA welded my sunroof panel in (staggered, not all the way!) and the paint shop filled the gap with screen mastic AFTER painting the car. From the outside it looks like the sunroof is still present.

well i didnt get the chance to have a look tonight so it will be tomorrow now (getting dark early is a pain)

did you get the car sprayed once the cage was in Uwe?

i half riveted and half spot welded my sunroof in. i figure it would make it easier to remove in the future. just as well as it doesn't look like its ever going to stop rusting so i may need to source another.

yes and yes again.

first time yes ,the inside was sprayed and just the roof (and the roof really bad I have to say)

second time yes was after I decided to park my car in the back of an E90 going into Dartford Tunnel (after doing 300kms in Brands Hatch) and the car was fully sprayed in jet black which was done really good.
Was shiny like a mirror!
