Can someone tell me what the standard ground clearance is for the FC is between the S5 front bumper (stock, with no lip) and the ground, as well as for the rear (lowest point of bumper)?

I suppose something that wasn't the front bumper would work for an S4, but I think just doing it with the front bumper would be easier...

I get the feeling that I may or may not have aftermarket springs, because, well, my car rides pretty bumpy to be stock springs... and I'm curious how far from stock my ride height is (that should tell me if they're stock or not).
