[V8] Suspension

[Coleman, David]

No rear bar exists that I know of -- I'm suggesting the addition of one to add stability (controllablity?) in addition to (or rather than) beefing up the front more.

Doesn't the '92 S4 have a rear bar?  I wonder if that's a cross-over fitment.  Also, I seem to recall something about some Camaro rear sway bar being a relatively close fit.

Lastly, thanks for clarifying the V8 versus standard A-arm configuration.  That makes more sense.
