I should add a bit to that question "on a Locost, not a racecar"

From memory, some Fords run about 20-25mm +ve on road cars. Bear in mind those are front engined cars. As per usual, Syd is off on his own and
misrepresenting me.
I think I mentioned in a post some time ago, though I can't find it, that 10-15mm was a good Locost figure for the road and is probably a good
start for the midi you refer to. I'm told some older cars ran much more scrub than 25mm.
On track, where suspensions are tauter and more responsive and the drivers are more attentive with adrenalin in their veins, then yes, closer
to zero is the way to go.
Cheers, Rorty.

Rorty,
Please explain this one perplexing question: Why MUST you always be seen to be correct?
What you have just written regarding dimensions, is more or less the same as what I wrote just previously. The comment on teaching came from the
people who actually teach this stuff. One of whom I spoke to on the weekend. If you know better, write a paper and get it published. Then go on a
lecture tour to inform the world, and make a million doing it. In the meantime, I'll stick with simple physics, and accepted engineering and
automotive convention and teaching.
Wimmera,
If you're using Cortina uprights and hubs, you're stuffed. The offsets are huge, much bigger than most cars before or since. The only
wheels I've seen close to the same offset are on the Austin/Morris 1300's. There was a last minute wheel size change in the design
process, which stuffed up a lot of geometry. (Or so the Ford engineers told me.)
Anything further I'll continue on u2u.
Please, anyone wishing to ask me questions or further discussion on this do it via u2u. This is getting petty, trite, and downright stupid.
Syd.
I don't mind being wrong Syd; it's a sad day when one doesn't learn something new.
I haven't changed my ground at all Syd, It's you who have swung around. Earlier in the thread when we were talking about scrub on cars
(race cars hadn't been mentioned until you stuck your head up), you lambasted me, saying the optimal setting was zero scrub, yet five posts
back, you amend your position stating "For road cars, the teaching is also that 25-30mm is the limit". That's the figure I
previously referred to a year or so ago.
You recently posted in another thread that you have the Ford factory drawings of the Cortina front suspension.
As The Book recommends the use of the Cortina front upright, and most people have probably gone that route, why don't you post it on here so we
can all learn from it and see the amount of scrub radius Ford bestowed on it for ourselves?
You do realise Syd, we're all in awe of you; you actually spoke to a teacher on the weekend. 
Cheers, Rorty.

The essential difference in our outlooks is that I know scrub as an evil and should be zero but up to 25-30mm is tolerable, though
not desirable. You say it is necessary.
Now, if all of this has been anything more than an ill conceived wind up, Mr.F-S, you are a very sad and lamentable person indeed. 
I know that thing in you demands you have the last word, but I'll be saying no more.
The rest of you can continue on the u2u, if you so wish.
Syd
Again, you misquote me to feather your arguments. Still, I take heart that we've heard the last of you, though you've promised that
before.
You demand answers from others, but when you're put on the spot, you recoil in your usual cowardly fashion. Where are the Ford factory drawings
of the Cortina Syd, or have you "misplaced" them?
You're an impostor Syd. You come on here hinting at race car industry connections, yet not once have we seen a single photo of your so called
expertise, or had even the smallest tid bit of authentication of your existence. What a croc!
You drop names without mentioning names.
You take great amusement from spelling my name out on the forum, yet you cower behind your synonym. Actually Syd, most people who give a damn already
know my name from U2Us or from my web site.
I'm broad shouldered Syd and can take all the crap you unleash on me off forum, but I just don’t understand how you can be so publicly bare
faced fraudulent.
You spout forth on occasions like someone who picks up gossip and tale ends of conversations in a pub or possibly some pits somewhere. Are you an
anorak Syd, mingling with drivers and mechanics, hanging on their every word?
You're a pusillanimous, egocentric prevaricator and you call me lamentable! 
Cheers, Rorty.

The unsuitability of the Cortina hubs & uprights was established early in the piece Syd, and I went into some detail about what I'd done to
overcome the problem, but my fix is not for everybody as it involves a fair amount of machining and general stuffing around, so I'll repeat the
question "what components do you use to achieve zero scrub?" the stage is set for you here Syd to really impress those of us who are
trying to build a better mousetrap and on a personal note would your middle name be Harbour by any chance.

I think this thread should finish now, the moderator on here should have pulled it long ago, trading of personal insults is daft so lets finish
now
