I've been doing the same thing since GT5. One lap of the Nords stock, then fully tuned on another test track of my choosing (GT5 was Trial Mt, GT6 was Silverstone, GT Sport was DTS and GT7 Deep Forest). Have another 150 odd cars left to do, then I still have the engine swapped cars. I didn't note my times tho, it was just for fun and I'm not a good enough driver to guarantee consistency over a 20 km lap.
I think you should redo the laps with default tyres the car comes in with. Supercars on Comfort tyres isn't how the car is intended to be driven from the factory and they will be severely handicapped handling and traction wise. Most supercars should be SH, and modern semislick tyres like the Michelin Cup 2R or Pirelli Trofeo R are equivalent to SM. RH for race cars is fine, but old race cars on bias ply tyres would be more accurate on SS tyres.
I would also redo the cars that were done with old physics. The earlier physics were way more oversteery, especially with MR cars. You'll notice a huge laptime difference.
Also if you're doing this in Time Trial, the wind direction changes and can impact top speed and handling. Best to do it in Custom Race with 1 AI (pick a super slow car so it won't bother you) and set conditions to constant. And put tyre wear and fuel consumption to 1x. With GT7 I find a lot of cars handle more realistically with fuel weight and tyre temps enabled.
A lot to unpack here. Here goes.
I did CS tires as roadbeef, a.k.a. Tristan Bayless did the same thing when he did something similar. When I asked, he said something along the lines of more realistic braking distances. I fully understand that super cars and hyper cars shouldn't be on CA tires, but it helped a bit with consistency.
Without looking at the spreadsheet, there are will over 200 laps that were done on older physics. I briefly contemplated restarting after the last physics update, but I decided against it. Perhaps in the future, I'll get to re-running them.
I've also complained about inconsistent conditions in time trial. Didn't think to use custom race to solve that, something else to consider in the future.
So, what were some of your favourites?
Ferrari F50, Porsche Cayman GT4, Ferrari 330 P4, basically anything in Gr.1 and 2.
I wanted to buy every car, and I said I would drive every car. I was inspired by roadbeef to run them on Nordschleife.
I like how you also use the paddles or stick shift depending on if the real cars use those, a neat detail i've noticed
I bought the shifter mainly for use in GT games. It was actually this game that helped me get better at heel toe shifting.
Thank you.
You mark this as a brag, but I don't really see it that way. A brag suggests it's something to be proud of, but I am proud that I haven't done that.
I get it. It's sad watching others achieve personal goals when they themsleves have achieved nothing. Someday, you'll do something noteworthy in your own life.
You know, something other than nothing.
