There seems to be much confusion re: fitments.
Beware that the dealer is not assuming that the
application for the 80/90Q fits. Most (all?)
Coupes and 90q20vs had the 24.5 mm lowered "sport"
suspention - generally packaged with the 205/50-15
Is the Koni application still "off the shelf"?
(and do you really want Koni sports (yellow)
on the street?) You live, amybe, below the frost line? :-)
