I'm really considering picking one of these up. I had previously purchased a knock-off GV, but sold it a couple of days later because I couldn't even make it out of my driveway. One thing I did notice was that it was significantly "thicker" (top to bottom) than an authentic GV lip. I knew this because - I'm 1.25 finger gap in front, and 1.5 finger gap in back and the lip was ~1" off the ground. Other cars on this forum are much lower than me, with authentic GV lips and they look like their front clearance is higher!

Anywho - if anyone can give me a number so I can measure it on my car. Thanks!
