Ok, so we can't know what car is faster unless a paid, professional driver is doing it. I was actually expecting to have someone say that I had too much experience to be "typical", so touche. I'm ok with bench racing until the cows come home.
The important thing to look for on that list I posted is the class.
S = Sport (basically filter, exhaust, tune, 200TW tires)
T = Tuner (a few more mods, 200TW)
M = Modified (full adjustable suspensions, internal engine modifications, 200TW)
U = Unlimited (race cars on slicks)
I run a basically stock Camaro ZL1 in the S1 class and I was the 7th fastest overall in a field of 100 cars. Most GT350R times I've seen wouldn't have broken the top 25.
Seat time, giving it 100% attention/focus, and having brains/balls will get great driver mod lap times.
I’ve personally left c7 z06’s in the dust in canyon runs in my 2003 fortified lasagna noodle because I felt comfortable going faster in the corners.
The real truth is a drive uses a car, just like the man makes the money.
You can probably go almost as fast in a ss 1le on the same track as you do with the zl1 because it shows you are carrying momentum and speed in corners. The vast majority of people struggle to toe the line and carry speed, then try to make up in the straights but wash out the next corner with late braking and ruin the next straight with late entry/slow entry.
To hone, start with slow cars and learn momentum. Also dramatically reduces engine temps, brake temps, and oil/fuel usage lap to lap since you are using physics instead of effort to carry and keep speed. You’ll use up tires the faster yer laps get usually though unless yer slow laps are ugly
