Sorry if this has already been brought up, but I just noticed that the weight of the F40 is higher then the weight shown in the Ferrari dealership for the F40. Anyone know whats up with that?.
The dealership shows 1100kg, whilst quicktune shows that at 100% the F40's weight is actually 1352kg.
Or am i going made from grinding that one race to get this car?.
Yup. See below. Personally I am very unhappy about this error. It is not a small error......I won't be so pissed if it is some unknown version of a Skyline GT-R that is only for sale in Mars, but the F40 is an icon of the automobile industry, the legacy of Enzo himself. If there is one car that they need to make it right in this game, it will have to be this car.
Simply put, PD nerfed the F40. Either by mistake or on purpose....
By the way, all the data I gathered for the US-Spec F40 is right out from a US-Spec F40 owners manual I happened to have.
Fact:
1) Ferrari F40 production car curb weight is 1100kg
2) Ferrari F40 US-Spec production car curb weight 1352kg
3) GT5P F40 is NOT a US-Spec car, per visual and showroom weight
4) GT5P F40 is a normal spec car, per showroom weight 1100kg.
5) GT5P F40 in QTS menu shows 1352kg as 100% weight.
6) GT5P had the same discrepancy across all versions.
Q) Could the 252kg difference be added weight like fuel and driver?
A) No, cause the showroom weight and the QTS menu weight is the same for all other cars, except for the F40. Showroom weight is defined as "curb weight" for cars. "curb weight" is defined as "the weight of an automobile with standard equipment and fuel, oil, and coolant".
Q) Could the F40 in GT5P be a US-Spec car?
A) US-spec Ferrari have very distinct visual changes to the original production F40 that are sold in the rest of the world. These visual changes are added body (and some hidden) features to comply with US safety laws. The F40 appeared in the game does not have those visual changes and the showroom clearly stated the weight as 1100kg.
Q) So how does this affect the car in game?
A) It will probably not be an issue if the QTS menu show 1100kg at 100% weight and the showroom data show something else. The problem now is the other way around with the car's 100% weight is 1352kg in the QTS menu. All the numbers appeared in the QTS menu is a "dynamic" part of the game code, hence any changes to it will affect how the car behaves in game. This means the incorrect weight in the QTS menu will have an negative affect on the car's in game behavior. While normally a slight difference in such data discrepancy is normal, however a HUGE 252kg (556lbs) discrepancy will have massive negative impact on the in game experience when using this vehicle.
Solution:
Revise the weight in the QTS menu to CORRECTLY reflect the weight of the production version of the actual F40.

P.S. Gearing for this car is also incorrect. While the gear ratio does correspond to the actual ratios used in the car, however, the corresponding speed associate to each gear is wrong.
) and that weight ratings are often given as either dry weight (no fluids, no battery), wet weight with fluids and curb weight including a full tank of gas, driver and one or two passengers, I doubt that anybody wants to go to all the trouble of lugging around a set of four scales to weigh every single car they test to make this game...
