If you want to race it, 50mm above your helmet is the go.
Depending on your seat height that may look a bit high though.

Mine sits "high" as I wanted the 50mm above head height.
Here is an old pic showing height with original seats when I attended my first Nationals.

My understanding is that you should draw a line from the top of the roll bar to the top of the front mud guard and your helmet should be under that?

Dave - you need to slouch when you roll over

Me I am a short arse so mine is ok :-)

Why? Your fibreglass guards won't hold up the front of the car

Rob does your chassis any provision for mounts already, or are you truly starting from scratch here? I can go get some details off mine, just want to know what exactly I should measure.

Modena as you know we have no mounting point on the chassis .. so yes from scratching of head does apply

now centre of seat area or just off centre .. hoops I have are 298 mm centre/ centre of 50mm x4mm alloy hoops
thanks ROB

For looks it would be good to centre behind seats

Guys,

Here's the link to the CAMS regs for roll bars / cages. The 50mm detail is on page 12. Good information is worth it's weight in saved money through re-work.

If you're building a replica Cobra....build it to look like a Cobra.....
If you are building a race car...then you should follow the CAMS guidelines.

My opinion too Wazz, if building a race car, build a cage.

When too many bars is never enough.... Just chuck a few extras in for good measure!
