Added Cantrell Motorsports, SCCA, and Turn2 Lapping to my Ratings page. Updated Audi notes.
I am now an advocate for open passing at track days with mandatory point-by. I used to think that open passing with a required point-by as being iffy at HPDE events, but once people get the hang of it, well, it keeps things moving SO much faster. Most clubs limit let-by/passing to designated straight zones, even for advance drivers. I think that’s a mistake.
The Cantrell Motorsports events run with the open-passing model and I really like it. I have a momentum car. When Colin’s fast turbo Porsche (and supercharged BRZ) clients rumble up, it’s great to be able to point them around under braking. Less instances of long throttle-off gaps on the straights. Although many of those cars can easily pass with a simple lift and back to WOT on a long straight, letting them around in an (appropriate) turn is awesome.
Some turns are not suited to passing/let by. The sequence might involve too much variability. It’s a judgement thing and managed by the car letting by. I’m thinking of the T1 to T5 at The Ridge. But all through the back there are great options for let by, including the long bit where there is normally no let-by permitted from T6 to T11 (although getting the passing done before T9 I think works best).
In any event, I’m a convert. YMMV.
