Speed-Tom,

thanks. Yes I build from scratch using 427 blueprints.
I found out that there is no thing as THE position for the roll centers, because it's always a compromise.

"a slightly angled down upper arm will provide an instant center that will create minimal camber change"

The slightly angled down upper wishbone positions the roll center below ground (F. Puhn, pg 36), which is "not usually used on high performance cars, but it does exist on some sedans".

So here is a compromise already. It is not explained why high performance cars don't use this.
I consider that and defenitely have an eye on bump steer.


cheers,

a friend of mine races a McLaren M8F, yes at 150 mph on the straight he can still not go full throttle...
