I'm also rolling 215-40-17's on mine. I didn't notice any difference at all from stock wheels. In fact, my .02 is that unless you are under full throttle at every stop light, you won't notice a difference for DD work... at least I didn't. But my car HANDLES so much better with the 215's on it, I figure whatever I lose in mileage upon acceleration I can make up in maintained speed through corners. I don't plan on going back to the stockies anytime soon. And if you get the right sized tire, you'd be in there.... yours are a little tall right now... 205/45's or 215/40's are what I would run as most people have already pointed out lol

MAT PROCESS: Shaping by the MAT process reduces wheel weight by 10%-15%. Every pound of unsprung weight savings has the effect of reducing overall vehicle weight by 20lbs. F1 REPLICA: Enkei is an official supplier of the McLaren Mercedes Formula One Team. The RPF1 was developed using the same technology as the Formula One race wheel. TWIN SPOKES: Enkei's dual open stance spoke design is used on the McLaren Mercedes Formula One race wheel. The twin spokes achieve better stress dispersion on curves, hard braking, and extreme race driving. CENTER DESIGN: Enkei's pocket design around the bolt circles increases rigidity and keeps the wheel cooler during aggressive race driving.
