I've seen some speculation on the board based on renders that the Performance trim is lower to the ground than the stock 3. We have a stock 3, and it works fine in our driveway, but my S (no air suspension) scrapes, and I was considering upgrading to a 3P based on the tax break and unlimited supercharging w/referral, but I'm concerned about a lower bottom. I should have taken a tap measure to my. test drive, but didn't discover this until after the drive. Can anyone confirm it's lower, and by how much?
