4kq vs 5kq rear suspension

[Mike Veglia]

I'm sure those much more experienced in suspension designs will chime in,
but, I have never heard the phrase "passive assist articulated rear wheel
steering" associated with 4kq rear suspension. Where did that come from?
What does it mean?

Anyway, the 4kq rear suspension is really the front suspension, backwards. I
have heard it called a "Chapman Strut" design, but am not 100% sure it is. I
adore 4kqs (and Ur-Qs of course) and have owned 4 of 'em to date (and drive
one pretty much all the time now).

However, the rear quattro suspension design first seen in the type 44 (5kq)
is a much more complex and, arguably, better design for the larger chassis
cars. The downside being a lot more bushings to replace when they wear out
though. For a rather large and heavy cars, the type 44, C4, etc. quattros
all are exceptional handling cars IMO.
