Yeah that was me. I was there with my mate Bill (black R34). That was one of the rare times that the car ran well.
I had slicks on the rear that day. Unbelievable grip compared to what I was used to.
I remember that 350Z clearly. I would catch him through the corners and then he'd pull away down the straight. I looked at all my gauges to see if there was something wrong. I expected to blast past him because I knew 350zs aren't fast.
It's true - there were a lot of fast cars there that day.
There have been a lot of issues with the car since then. That day was 3 engines ago!
I have recently set my reliability record - 4 full track days with no serious issues, and still going strong.
