I know lots of folks on this forum are a little quick to think about chopping everything 9"+, but you have to give it some thought -
It fits the style of the build. A hot rod '40 coupe would look goofy with an aggressive chop. The 1" chop is a lot of work, but it will keep the flow of the car for the look they are going for and still have folks scratching their heads as to why it looks just a little different. Sometimes it's the subtle things that are most satisfying.
As an example, there was a '64 Riviera at Detroit Autorama a few years back. SUPER slick, nice, bitchin' car all around. Now I love me some Rivi's and I always check them out, but this one just had "something" that had me drooling at first sight. As I'm reading down the list of mods, there it is - 1.5" chop. It was done so well you would have never thought to guess it, but it made the car stand out SO much. Any more and the car would have looked squashed and hacked, and without it was just another nice car. Made me a believer!
