cup racer rear harness bar

[sam JFM]

Am I right in thinking that it's just 6 bolts through the rear arch that hold the cup car cage harness bar in?

It's part of the roll cage - it's not just 6 bolts

 

[sam JFM]

Yeah but it's 6 bolts that attach it to the shell?

 

[Cup_Phil]

If there's 6 holes in the feet then yes.

Have you looked at the pictures above?

I have - I even own the cage I was just making sure mine wasn't missing anything

It will have welded in spreader plates

Ooh mine only has the 2mm plate with the holes in that is attached to the cage tube and nothing else?

What is your interpretation of the blue book regs when it comes to back stay reinforcement plates?

The backstay feet of my cage have been welded to the body without any additional reinforcement and i am not sure how to get around it? Its going to be difficult to cut out, i am wondering if i can weld a spreader plate over the top of the foot plate, and then weld the backstay tubes to the spreader a few mm further up?

Welded plate to the wheel arch then drill three hole in it to bolt the plate from the cage onto.

Thats the way i would like to do it but its already been welded to the arch and i cant see an easy way of cutting it out...

Shocking picture but! that is a rough drawing of the rear arch with the cage welded to it - what i wondered if i could do would be the additions in red( the red sprays and weld) and obviously fill in the gap betweek the plate and the weld

 

[Cup_Phil]

A lot of people put spreader plates on the bottom. There's absolutely no room with some of the cages to put spreader plates on the top of the arch. My cage actually bent the arch when fitting so I put spreader plates on the underside

Thats an option - just a t**t to weld upside down! what did you use to plate it? 3mm?

 

[Cup_Phil]

I think it was something around 3mm yeah.

TBH welding in the cage feet is the only job I've outsourced to someone else (mines not a cup racer cage btw) - because I can't weld

And watching him do the front feet with his head under the dash, a wet towel over his head and holding up a piece of welding mask glass in front of his eyes - it's something I'd never want to get into lol

Awkward as hell

 

[sam JFM]

Lol the racer cage plates are quite easy because of the length of the legs, just the bloody rear ones now that its been welded.




Have you got any pictures of the rear arch phil?
