hey exec,
my 2 cents - its your car: you do what you want to it.
i bite my lip once in a while when some truly horrific mods create an obscene, abomination of a coupe - and i have to remind myself that its their car, their time, their money. as you know from the p-car side of the internet, you are not asking the equivalent of taking an rs and grafting on turbo flares, impact bumpers, whaletail, and etc. most people would say that you are proposing improvements. personally, i have a hard time making any "permanent" changes - which means that i have an engine, transmission, wheels, seats, steering wheel, etc sitting around in case i need to put everything back to factory spec.
btw, i love these kind of threads because people send in photos of their coupes. mpgandco both of your coupes are uber-cool! and, i remember your friend's coupes - i think i posted links when they were being advertised on the bmwcca site. but i just looked at the photos again/for the first time. that white coupe does have a menacing look to it. also never noticed the front corner of a '73 911s (?) in the 3rd photo.
