I think it looks fantastic! There's still a small bit of gap present when it's "as it sits" but honestly there are just a few manufactuers in the world that have figured out the wheel gap vs clearance issue -PLUS- with clearance so minimal in a car like the Viper it's just not worth it to put it in the weeds if you have a steep driveway or speed bumps in your 'flight plan' After all, there is such a thing as "too low for a daily driver. I'd much rather deal with a tiny bit of gap vs scraping everything (after lowering 2 of my cars to eliminate all gap I now deal with scraping or rerouting how I'm getting from A to B)
Also, have you looked at the car from other cars? I find that my perceptions of certain cars and their "good angles" can change depening on whether or not I'm looking at said cars from a stand, crouch or riding in another car. I'd wager that the gap is hardly noticable whatsoever from the riding position of another car.
Speaking of the gaps - of all of my cars, only the BMWs fill out the wheel wells "Cleanly" with very little gap. The M Coupe has just enough gap both front and rear to get your hand flat atop the tire - and no more. If you're trying to wash down the interior wells for example you have to arc and reach just to keep from slicing your wrists so a little gap DOES have it's advantages!
The rear gap % does look a touch bigger than the front, all things being equal. Those rims really shine with the silver - what a combo! That's what I meant by the "my eyes!" comment - the gleam on your car is enough to guide lost ships to shore!
Take care and enjoy!!
