position of roll bars
help guys i'm just starting to set up to drill holes for my rollbars ,& as its a venom motor sports
yes a mr tuckers I have no reference points to go on accept 100mm from inside edge of rear cock pit [ rear fire wall ] so do I pick centre of head rest or slightly off centre what lay back on the hoops level to top of wind screen ? FOR HEIGHT as its raining// so I can dummie fit, SO as to get them cut & welded thanks a head ROB |
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. http://i270.photobucket.com/albums/j...Cobra_0296.jpg |

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 :-) |

thanks for your in put but i need to know where to put the holes & what spaces are needed ? what lay back on the hoops
if you have pics that would help thanks ROB |
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.

I think the angle they lay back is 8 degrees.

Modena as you know we have no mounting point on the chassis .. so yes from scratching of head does apply
wazza thanks 8 degrees helps a lot 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. http://www.camsmanual.com.au/pdf/10_...e_J_2013-5.pdf Treeve |
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!
