My instructor at Lime Rock, later that summer, had an 85. I didn't
drive hers, but she immediately commented on how much more solid the
stearing felt.
Could have been different tahrs, or sumptin.....
All the 4KQs share similar suspension to that of the ur-q.
I know of no differences in the steering between ur-qs and the 84-87 4KQs.
