I'll start with a positive: the model itself is reasonable. For 2023 Assetto it's certainly nothing special, but it's at least on Kunos quality.
The not positive:
The car uses a lot of Kunos data. This doesn't make it outright bad, but transparency is important - if you're going to reskin the Audi TT Cup, tell people you've reskinned the Audi TT Cup.
- Tyres are entirely copied from the TT Cup. This is despite the cars having different tyre widths (plus the Kunos tyres aren't great anyway).
- Aero is entirely copied from the TT Cup, with a tiny change to span, so CM doesn't flag it when you analyse the car.
- Rear suspension is still from the 70's Porsche as Raymond highlighted - all they did to "update" the geometry was another trick to get CM to not flag it without really changing anything - the top wishbone was made ridiculously wide.
I'm not saying the last two points had malicious intent to get around CM's analyser, but it's not a good look.
The not copied data:
- The engine is... interesting. Would love to see a dyno graph matching this. It's also running way too little boost - publicly available TCR BoP sheets show all cars in the region of 1.5 bar, this mod is running ~0.5. UI curve also doesn't match the actual curve.
- Brakes seem good! No complaints here.
It's great that you guys are trying to bring these cars to Assetto Corsa, but I wish you were actually doing that, and not just reskinning/kitbashing existing cars.
