That's a great anecdote! 👍 Did your friend happen to mention ANY cars that feel like the real thing? I've always had a BIG issue with GT6. Frankly, I don't believe that 90% or more of the street cars that we purchase from the Dealership are setup to resemble the real life car we are purchasing. If you take a Corvette C7, for example, it might get the ride height accurate, but I find it impossible to believe that damper compression & extension would be set to "softest possible" because then you have no way of softening the dampers, you can only make them firmer/stronger in your adjustment from "stock".
Then we have the anti-roll bar settings. Again, if a stock C7 Vette really came with the setting that GT6 gives you (1/1), in real life, there would only be the ability to make the ARB stiffer and not weaker/less stiff. Now we move on to camber and regardless of how you view GT6's poor implementation of camber, are you telling me that 90% of road cars come with -0.5 degrees of front camber and -1.5 degrees of camber in the rear? Because GT6 seems to think so. Finally, we move on to toe angle were GT6 leads us to believe that our beloved C7 Corvette, along with the majority of road cars has 0.0 degrees in the front and +0.60 degrees in the rear. Obviously, this can NOT be accurate as to how the real life car is setup.
GT6 often gets the vehicle weight right, but it also incorrectly states stock vehicle weight a lot, sometimes by many, many kilograms. That Aventador that we all love throwing around the Nurburgring? Well, GT6's listed weight is actually 146kg (321.87 pounds) too light if you believe Car & Driver or 157kg (346.13 pounds) too light if you believe Motor Trend. Either way, the real car is MUCH heavier than the car they give us as completely stock from the dealership.
Fortunately, GT6 usually seems to get the transmission gear ratios correct, although there are some exceptions here as well. The area they seem to usually be spot on, as far as street cars go, is with the horsepower and torque. Again, there are even exceptions for those figures on some cars. Lastly, most cars seem to come with a generic LSD setting and most people would agree that the stock tires applied to street cars in GT6 are way too grippy, ie. track-only quality tires installed on a luxury sedan.
Personally, that is why the majority of my cars have been "tuned" with
@Ridox2JZGTE tunes from the
Ridox Replica Garage. His replica tunes are not meant to be the fastest tunes published on GT6. He strives to give the most realistic interpretation of our available cars in GT6 based on adjusting all the incorrect base settings to their proper settings; matching real world weight, power & torque, suspension, transmission, drivetrain and aero settings to the respective cars. Now, whether they drive anything like the real world version of the car is up to GT6's physics. I put the word tuned in quotation marks because I don't believe he's really tuning the car as much as he's just trying to setup the car the way it should have been setup in the first place. To me, "tuning" is when you start putting racing brakes on your sports car with weight reduction, a new exhaust and adjusting the suspension from the REAL stock settings.
I know I went on quite the ramble here, but I think it is very important to make it clear that it shouldn't be a surprise that your friend said the Ferrari F40 in this game doesn't drive like the real world F40. It's not setup like the real F40 is at all! At least, that is my opinion on things...
EDIT: I should add that Ridox Replica Garage also has some "bonus tunes" where he isn't necessarily setting up cars to match their real world stock settings, but rather providing the more traditional sense of what we call tuning in GT6.
Also, I know there are other replica builders here on GTPlanet, but I am most familiar with Ridox Replica Garage, so I used his garage as my example. Plus, I really, really love driving his car builds!
