Before you all go "omg you're slow as molasses..."
Yes I don't push either one of my cars on track that hard. I leave a nice, safe margin for error at all times. Yes I know I'm easily 5-7 seconds off pace with either car. I've ridden with instructor and club racer friends that leaves little to nothing to chance and it's fun and thrilling as heck, but I do tend to drive a little on the conservative side because, well, I'm not out to set lap records.
But I am consistent as heck. My hot laps are usually between .2-.5 of reference laps, baring traffic, once I'm warmed up. So I can tell you I hit my marks and while I can probably shave off a few tenth each corner by braking later and throttle in earlier, I know my wife would literally kill me if the accident didn't.
So, enjoy. I'm sure if it's not my car, my tires, and my fuel, I'd probably be able to shave another 2-3 seconds off per lap easily.
