Thanks for the tip on the AVS-I's.  Actually, I would rather put 205/50s
on if I could find them in 14" size.  I want the diameter to be smaller
to give the car a little boost in acceleration.  I had 185/60-13s on my
old Prelude which replaced 175/70s and made a significant improvement in
performance.  I just made a mental correction to the speedometer reading
(and usually drive more by the tach anyway, once I get a feel for the
speeds in various gears).
