The reason why the GT-R is so widely used is because of its handling, which BoP unfortunately does not affect. The 2016 cars by design all have nearly identical perfomance, but the GT-R is simply the best handing one.
The reason why the old Super GT cars can’t keep up is simply because they’re 8 years older, so it’s just outdated machinery. No reason to use them unless you just want to have fun online.
The easiest way to find the livery you’re looking for would just be to ask the person who used it on PSN where they got it from. If it’s a popular livery it shouldn’t be to hard to find in the Discover tab.
I quite often read this, but I'm not convinced that's the case.
Here's an example I could quickly find on my spreadsheet.
I avoided comparisons before and after the tyre model change (v1.23), so I checked Gr.1 stats. from v1.12 and v1.20
The numbers represent the following:
Power Torque Weight Power/Weight Max. Speed Acceleration Braking Cornering Stability
All 4 cars have the same Power, Torque, and Weight for both game versions, but...
(v1.12)Alpine VGT 2017 RR 576 54.9 930 0.619
9.6 5.7 6.1 6.1
6.1
(v1.20)Alpine VGT 2017 RR 576 54.9 930 0.619
9.5 5.7 6.1 6.1
6.4
*Lower Max. Speed - Higher Stability*

*Lower Max. Speed - Lower Braking, Cornering, Stability*
Here's Gr.2 after the updated tyre model, comparing v1.24 to v1.29:
(v1.24)Honda NSX '16 MR 603 62.5 1049 0.575 7.7 6.4 5.3 5.3

(v1.29)Honda NSX '16 MR 603 62.5 1049 0.575 7.7 6.4 5.3 5.3
5.9
*Higher stability*
(v1.24)Lexus RC F '16 FR 614 60.0 1020 0.602 7.7 6.3 5.3 5.3 6.2
(v1.29)Lexus RC F '16 FR 614 60.0 1020 0.602 7.7 6.3 5.3 5.3 6.2
*No change*
(v1.24)Nissan GT-R '16 FR 612 60.0 1020 0.600 7.7 6.3 5.3 5.3 6.1
(v1.29)Nissan GT-R '16 FR 612 60.0 1020 0.600 7.7 6.3 5.3 5.3 6.1
*No change*
It's something I've always been going to do, but never got around to doing.
So this time I've taken some screen-shots of all 6 of the Gr.2 cars as they are now, and I'll cross-reference their settings with the next update (assuming there are some changes).
But it seems to me that BoP is more than just small changes of power and/or weight.
