S3 roll over bar dimensions

Recommended Posts

Hi all, I would like some assistance with the dimensions of the current S3 chassis roll bar. I could take a guess from the pictures however, to have some details of a factory one will assist.

if there is a link that would be great, if not the following will help.

I plan to have one made as the freight to the colonies for a factory one is prohibitive.

i only plan to use one for a road car,

What Diameter tube is the current road bar

what height are they from there mount base.

Lastly the angle from the vertical.

many thanks in advance.

Good suggestion, however I will clarify the question to a standard Caterham bar, the reason is key issue is that Caterham no longer have a listing for the live axle cars, and redline website is only really an inquiry only site.

B.T.W. one issue you are likely to encounter is that the bars were made on a jig, not to dimensions on a drawing.

Even today, I am given to understand, the present rollbars (ROPS) are made to match a master, not to engineering drawings. In this age of CAD and computer based analysis of structures and materials I find this astonishing.

Like the OP, almost two years ago, I am trying to find the original/standard width and height of a roll bar on a 1963 S2.  I've read all the above comments. Intriguing! If anybody has one, can they please measure and post? And how far apart are the rear 35 degree (?) bars?

Jonathan Kay suggested posting a pic.  Like the attached.

I'm in Miami, Florida.  Bruce must be really old school!  E-mail is celebrating 27 years!

Unsure if I'm surprised, dismayed, shocked, or all three, but auyt asked the question 2 1/2 years ago on 22/08/17, and still no reply! The answer has to be something like 1185mm x 315mm (46 3/4" x 12 1/2" in old school), exact would be helpful.

I'll call Bruce's rotary dial on Monday!

Gotta love Forums!

Get out & drive!
