Sadly, being concerned about wheel gap and/or ground clearance are both incorrect. What people SHOULD be concerned with is PERFORMANCE. If you have optimum geometry and maximum grip with it 8" off the ground (stock mustang), then you should be 8" off the ground. Nothing is optimal in the stock mustang suspension, so please don't leave your mustang high in the air on its factory 4x4 suspension.
I'm just saying that the focus of any and all modifications done to a vehicle's suspension should be to improve handling, not reducing something so trivial as the wheel-to-fender gap.
This mindset is 100% correct in a performance application.
Blah blah blah performance blah blah blah. I just want zero wheelgap and I'm happy.
This mindset is 100% correct in today's "street scene".
Anyways.... Ryan, paint the car orange you ****er.
Then there's this guy...
