Rorty's IRS
good evening,
Is the Rorty IRS back end wheel track wider than an escort live axle wheel track?

Both of rortys designs are the same width as the escort axle if i remember correctly. And therefore both require that the sierra halfshafts are
shortened.
I am sure the details are in the drawings.

There is a drawing knocking about which has another system using the Sierra trailng arms, which is pretty heavy, I'll see if I can find it.
Or you could buy my book and shorten the driveshafts
Or just buy the book and not shorten the driveshafts.
So long as you buy the book, my granny needs an operation or something...
Cheers

If you are building a 442 ie 4 inches wider +4 inches extra in the cockpit and 2 inches higher in the frame, then it is suited to sierra half shafts
etc but will need the rorty rear to be amended to give the extra width. I did do all of the calcs on instantaneous centre associated with moving the
frame rails that the wishbones hang from 4 inches further apart and this had a negligable effect on the roll centre but did mean that I could use the
half shafts as is which meant no cutting no rewelding and no balancing. Certainlt a win win in my book!
Best of luck

Where did you get the French version? I was trying to get a copy but couldn't find one. Not trying to give Chris any extra beer money though

Apparently, I don't get into the legal stuff but I presume they did their homework.
(I hope they did, you've got me worried now!)

Interesting one this Chris. Not at all my subject. The only involvement I have had is in protecting product names for products I had designed.
Here's a link to Caterhams details.
