Half Cages

[static1800]

I've noticed them in a lot of build ups before nad wondered about them. I'm guessing a lot of them are merely for show purposes but are they actually of any use?

I think it's pretty much impossible to have a full cage in a road car due to the rules but i'm guessing a half cage is legal due to it not getting in the way?

Would they be of any use for a track/road car for super sprints and stuff? or just not worth the effort?

frankly a half cage is a bit of a waste of time as it will not really stiffen the car up that much and will add weight which is any mk1's enemy. I have a full cage in my car for tarmac rallies and it is surprising how much it stiffens the shell up

It's worth the effort if you go arse up in a big way, but as has already been said, it makes little difference to the rigidity of the chassis. It will, however brace your rear shock towers if they are not already tied in..

did you run the OMP cage in your mk1?

do you recommend those cages?

Yeah that's kinda what I was thinking. I reckon a good rear strut brace would be the go for the rear end and some seam welding

That's what i'm going to do.

They also make for a convenient place for mounting the seat belts!

Check your class regs. Some classes don't allow strut braces unless they're built into the cage.

But if they're there to anchor the belts.......

That's what i was going to do. I got the idea from yours actually, Pete..

I'll tell you what, having driven quozl's car with the bolt in cage as well as mine there is a big difference between the two in terms of stiffness and that's just on the road. The car is like the same but not the same.
You just don't get that same feeling in my car (not that I'm complaining about my car).

What other suspension differences are there between yours and Quozls?

[the scotsman]

for any motorsport a cage is a good idea.
Any cage will tighten up your shell, but even with a bolt in cage the shell will flex around it. If you can, and the regs allow brackets attaching it to the A and B pillars will make a huge change.

KW V3 coilovers on quozls vs Koni Yellow adjustables and H&R springs. Both have the same swaybars and a TST rear brace.
It's just a better feeling with the whole car which is probably a whole combination of things or it might be all in my head but yeah that's my thoughts.

On the subject of the TST rear brace putting this in makes a big difference in the car. The flex is reduced quite a bit and when you fold down the rear seats you can hear the thing flexing and straining from the forces trying to flex.

I also have different spring rates to the standard KW V3 Springs. The full cage definitely stiffens the car up, it is legal with an engineering certificate and plate (which I have) in QLD as long as the side intrusion bars are removable and not higher than the side of the seat.

Personally half cages are a waste of time!!! A cage to work at full potential must connect to the chassis for supreme stiffness...
