December 10, 2008 - The other option for the rear is a four-link setup.
It's a little more elegant from an engineering standpoint - the axle is nicely constrained. But it's more of a challenge to design well, as there's potential for binding. I have to admit I'm not completely sure how to design that, or if it's really a risk. I've been running the kinematics of both designs in my head all day, trying to figure it all out.
The picture is of a commercially available kit from Classic Conversions, and it's actually designed to bolt into the chassis. Pretty nice. According to a writeup (with more pictures) on BritishV8.org, it's designed to have a bit of roll oversteer which is something I'd prefer to avoid. Still, it's a good option - although with a price of over $1000, it's more likely that I'll use it as a proof-of-concept.
