What are the roads like where you live, T?? I've ran with less than 3" ground clearance, but you have to be very observant of your surroundings. Speed bumps look like Mt. Everest, driveways are for the most part a place where other people drive, etc. Hard to tell what your ride height really is until you drive the car some, and bounce the suspension a bit so it settles down to it's final ride height. In general 4 is low, but if you watch what you're doing you should be ok.
