I'm heading to the drag race event next weekend and I can only take one set of wheels with me (what's on the car). This will be the only race I'll be participating in this year so I want to go out and get the best times possible (yes, i'm keeping all the interior in). The V12s provide a little more traction over the RE050A but the increased wheel diameter and weight of the Stance Wheels is what concerns me.

Anyone have evidence that shows the difference in time/trap speed is significant enough to to swap out for the OEMs?

Bro, just lower the air pressure in the OEM setup down to 20lbs for the rear tires and call it a day.

The less rotational weight/unsprung weight will be the better.

But how much difference in time are we talking about? If it's just a mere .10 seconds I think i'll keep the 20s on so my car will look good running too.

Well if you want to know exact times, better find away to take the jack, some stands and the wheels to the strip to find out. Its impossible for US to tell YOU what exact TIME you will get with YOUR wheels.
