Anyone have a link to a good online translation site :wink:



Mine is actually a combination of seveal of those. I also studied a few WRC cars before deciding on the final design/layout. Other factors such as getting in and out easily were also taken into consideration. The cage offers no guarantees, but I'm willing to bet that it will allow my co-driver and I to at least survive a pretty bad smash if I do something silly.

Make sure it isn't a basic one - wouldn't trust one of those if I had a big off. Look at what happened to Michael Park in the WRC a few weeks ago. FIA standard cage couldn't save his life. You wouldn't stand much chance in a car with a few simple bars :wink:

Dad has been building roll cages for years and years and actually built the prototype rollcage for Ford Aus that all the current V8 supercars have to use.

Sure the roll cage is there for if you crash, but nowday's most of the bars are there for structural rigidity to help performance.
Think of the theory in a strut brace, and think of the roll cage as a mega strut brace.
Some of the WRC cars had up to and over 40 metres of tube in them.
Some say a bit of an overkill for protection, but all the bars are there for a reason, and most are to to help performance.
The less the shell bends, the better the suspension works.

Also, the diagrams that have been shown from the motorsport website,
they are minimun requirements. You can have one of those cages then add more bars.

Yes, exactly what he just said. The cage diagrams 253-3 253-4 or 253-5 are the minimum. You can add damn near any bar to those structures, so long as you respect the door opening measurements and windscreen measurements (new regulations this year!).

For a road car with a rollcage, throw away your back seat.

Well you could alloy panel the area, but the key point is back seat passengers with a cage is not safe and will be bloody hard if not impossible to get legal. Besides, it saves weight :wink:

What are you actually wanting to achieve? A proper race car or a fast street car? :?

If you want a race car... you will have to make sacrafices. Forget about the backseats and cosmetic issues. There's nothing that looks harder on the road than a 'street legal pure bred race car'. Forget about seats for your mates in the back... tell them to build their own cars. 8)
Your Opinion Means 1/16th Of Stuff All To Me So Dont Bother Arguing With Me About It As I Just Dont Care.

You need to think hard about your goals for the car. For instance have you studied the class limits in the sport you are attempting to compete in? In most motorsports there is a 1600cc NA limit, then possibly a 2ltr compressed limit, then open. So to begin with you are on the back foot, attempting to compete with developed 2ltr turbo cars. Have you thought about insurance? Compliance?
Loosing the back seat is the least of your worries. And using a race car on the road can get tiring quickly. No noise reduction, screaming box, uncomfortable suspension, clutch that bites at the slightest movement, etc etc etc.
I had the same thoughts as you with one of my AE96 rally cars. However I quickly bought another car as a run about.
The answer is Helmholtz!

You sound confused and possibly misdirected. I suggest you hang out with some people who actually race and learn a bit about racing before spending any money. Which car club do you belong to?

Hi Callum, surf over to Schedule A of Manual 33 You'll want to look for the red coloured text in article 4.4 and then the diagrams in the last pages of that document.

Reply to the other dude...You can't have a road legal car with back seats. If you put in roll protection, then you can't have rear passengers ever, it would be unspeakably stupid and dangerous.

Thanks Leon
Going to the professionals (as soon as I find one I'm happy with) for the cage and need the biggest door opening possible to get my fat arse through anyway so should be no problems :oops:
Good thing its a two door. :wink:

i belong to the northern sports car club. my run about is a 2003 VW gold TDI. stripping the back seats out isnt too much of an issue, ive just seen alot of dodgy looking jobs and i dont want my car to look tacky. if u can plate over the area and make it took neat and tidy without lookign like it was done out in the sticks with a lighter and some chewing gum thats fine.
in regards to the class hes there is a 1600cc N/A and a 2ltr FI class. for starteers i will be in witht he 1600cc N/A class and i would like to move up to compete with the 2ltrs in the futre. i dont wanna get a huge almighty roket, jump on the track and kill myself. im starting off small as im new to the race scene

strip it out, then tidy up any ugly bits and then paint it.
