I'm just curious. What's the basis for your opinion on this?

Is this the little vertical tube you're talking about? How would you have done it differently?

THIS.

that is ALOT of X support bracing for a roll bar...

why didn't you just go all the way and add the front hoops and A pillar support to finish off the full cage?

Also.. where you going to put the harness bar? or are you just going to loop back to the new rear strut tower brace?

The metal around the struts turret tops is very thin, adding in these tubes and the way the down leg is welded so force is transmitted back down to the man foot on the chassis leg is stronger than just welding it to the rear metal alone.

Yes its a lot of X bracing as this is the rear section for the the full FIA race spec cage. I didn't want the full cage yet as i still use the car on the road a lot and don't fancy the chance of hitting my head (with no hemet) on the A pillar bars. Also huge door X's mean I would have to lose my door cards and makes getting in and out a PITA.

When the car becomes 95% track and 5% road ill convert to a full cage then.

Harness's can be fitted to the small tubes in the rear X or looped around the rear strut bar.

As for seats Im gonna be using stock leathers for a month until my kevlar buckets get here.

And yeah ok guys its a roll bar not a cage, Just thats what most people call these things! lol..

tarted finishing the last bits of colour this morning and just put the fist part of the clear coat on now.

While the clear coat is drying out i've made some small brackets for the seat lap belt to screw to.

Eye bolt for the lap belt. with nylock nut.

3mm stainless steel plates. Centre punched and drilled from 3mm up to 11mm for eyebolt and 10mm for the bolt to the chassis. This took me 30min to drill these little bloody things! SS is very hard to drill!

are your eyelet SS plates mounting to a seperate location from the OE seat holes? or same?

i would suggest you mount independently from the seat's own mounting points...(i.e drill thru the floor independently)

Looks great man i like that your painting it body color really clean, i was also wondering about the harness bar but suspected you were going to use those small pieces connected to the rear downs. What size tubing is that?

The fellow who did the welding must be quite a contortionist and a great welder. Getting into those tight places and still doing such a good job is impressive, even to someone who has done a fair amount of TIG welding. A tip of my welding helmet to him.

Well, after the mad rush to get the car painted ready for going to the britcar 24H race over here in the UK its sort of done! lol...The cage is done and floor is 95% done. I still need to finish the back rear panel but this will be easy to mask off and paint next week.

Some pic's I took before leaving to go to the brit car. (dont mind the harness mounts, these will go onto the roll bar when the extra scroth clips arive in the post) Ps. I need my new seats to hurry up too! lol..

Yeah I know mate, The low mount point was just to get me on the road last weekend. The new mounting on the roll bar is spec'ed to the schroth website's fitting guide for harness angles etc. Thanks anyway.

Mount the harnesses on the harness bar & get better seats! Awesome cage though, I really like your work. I agree on some of the comments about the mounting of the rear strut tower area but you did a great job.

The cage work is 95% complete. I just need to finish the very rear boot floor and rear bulk head area. the next job is getting the head line back in. the head liner will require mod's to get it to fit as the cage main hoop sits very close to the roof skin and the head liner will not fit through the gap. Im still not sure how im going to do this but Ill get it done some how :ninja:

Im going to make a rear boot mat from thick carpet thats a good sound deadener that can be thrown in and out quickly for long drives as the cars quite loud inside now! :P

These are the last pic's I have of the cage.

Car packed up ready for nissansportz national!
