Any video of the first drive? We want to see!

And I really can't imagine turning radius being a deal breaker... at least not imo. I haven't noticed anything particularly weird in our 818's turning radius. We are running 235's for street tires (rub slightly at full lock) and 245's for race tires (don't rub because they are 15's).

And the 818 is no Z06? That's an easy fix with a few upgrades Quick google search tells me that the 2015 Z06 weighs 3524lbs and dyno'd at 585 RWHP (i'm using WHP because that's what I can compare to our 818 dyno results), which is a lbs per whp of 6.02. Our 818 dyno'd at 310whp for break in, and assuming 1800lbs, gives it a ratio of 5.8. Plus that's just our break in tune....
