roll centers, rear uprights

[Dominik]

tom,

I contacted Milliken and must say their books are quite expensive, which they admitted.
the rear now higher than the front? that makes more sense looking at the measurements of a 427.

that would explain why the the 427's rear upright is higher (longer) than mine. I can change that easily.
It's only a dummy for now.

rick,

I post pics once I am happy with what I can post - especially the background, which is my messy garage :-)
unequal, unparallel a-arms is what I got. so I am at least not incorrect here.
the car I raced (see below) had almost parallel / equal length suspension in the rear.

scott,

I am shipping an excellently handling car this monday to germany.
I was comfortably cruising into second behind John Atkins' race prepared (still street legal) 289.
just one second slower per lap, with less power, and I am a beginner.

that car also features (FORD) McPherson strut in the front and a 289-like homemade rear with coil-overs.
it was built by a very well known racer/car builder in south-africa.

bump steer is a good point. I defenitely consider your input.
Tony Martin from BDR was there and watched me in the first heat.

bruce,

yes, you are right. but like I said, I just do not want to mess it up completely while I have the chance.
and I saw some Cobras really change behaviour once they went to 17" tires - which is not what I want.
I am too old to become a schuhmacher.
fangio? maybe... ;-)

Okay, back to the drawing board and playing with roll-centers. I keep the rear now where it is (quite original), as high as the front (or move it higher) and carry on.

otherwise I will never finish... - although, I wait for more input.

and yes, I would buy a Kirkham for originality (I had a good look at Fritz' car in Germany), but importing is quite expensive - I aquired a house instead...

thanks again for your thoughts,

dom, cape town
