roll centers, rear uprights

[Dominik]

rick,

good thoughts. thanks.
the rear lower than the front? no problem, I can change that with the upright.
I could consider two mounting positions for the upper (rear) wishbone to the upright.

a lot of uprights available is correct, but typical engineering shop cost of USD 20 to 25 in south-africa easily allow me to make an upright (with a bolt-on bearing housing/retainer from a GB FORD Sierra/Sierra)

the chassis is very loosely based on the 427 chassis.
I always wanted one and I am willing to trade some handling for originality.

my best bet is to use a 289 style rear suspension instead of 427, but then I loose the anti-squat built into the 427.
tracion out of the corner may suffer, the first chassis is 90% finished and I do not want to modify it - design is "frozen" ;-)
maybe the next one.

I read all of C.Smith's books and paul van valkenb... as well as fred puhn's.

it's not really explained what one really wants.
I do not expect it to be perfect, but I just do not want to mess it up completely.

I can lean on the original 427 upright's dimensions, to simulate their behaviour, but it may be a compromise for street use.
427s were also (mainly?) built for street use.

as I understand, the front roll center of a 427 is about 2" above ground and the rear 1".

rubber:
BFGs... - unfortunately. Importing is very expensive, so we use the cheapest. I would prefer Hoosiers if I had that option.

rear roll center lower than the front seem to be the way to go.

thanks,

dom
