Interesting ... I've never had any trouble lifting the inside rear wheel of
ANY 4k/Coupe -- stock or modifed -- off the ground under hard cornering.  I
assume you know that once you do, you've transferred all the weight you can
and the rear bar has no further effect whatsoever.  In my experience, there
is very little benefit to a rear bar on these cars once you're driving over
7/10ths ... Yes, it helps transient feel during normal driving but it won't
make any difference at the limit, especially if you're on sticky tires.

(BTW, you don't really need to add a bar anyway ... weld a few small pieces
of 1/8" plate across the axle channel and you can accomplish the same thing
with a lot less weight AND cost!)
