What time difference would you speculate this set up would add vrs the 17" dr's ?
Your setup is nearly an inch taller than OEM... And, quite a bit heavier to boot.
Ignore the rim width/backspacing, as I just put something in there to fill the void...
This gives you a visual reference of how much taller the wheels/tires are. To alleviate this with a 20" wheel, you'd have to drop to a 25-series tire... not worth the risk of bent rims and zero cushion IMO...
