Same car, same wheels, with a stick. 1" wheel spacers and a throttle controller. I used a non-adjustable saleen model. There are many. Those two relatively inexpensive mods will change the look of the car externally (fills out wheel wells), and dramatically change the throttle response...
We're not talking about the front the car. We're talking about the hood vent assembly on top of the hood. The vents themselves create a high pressure area just in front of them, resulting on a low pressure area on top and right behind them. That's what "pulls" air though them at speed...
The hood vents will create a low pressure spot on the center of the hood, and when going fast enough the hood can flutter. That's what you're seeing. Check out the hood bump stops (rotate to adjust).... check the rear hinge assy for up/down slop. I've never experienced that in the S650...
It's a GT (Grand Tourer ... like a 928 GT). You want a "GT3" version of the mustang GT... .get a loaded Dark Horse. Personally... having come from 18 years of road racing, owning 25 911's over the years, Ferraris, etc... The GT does GT perfectly. The tall gearing is great.... Nice bit torquey...
Go to amazon and buy a coolant tester to test if there are any hydrocarbons/COâ‚‚ in the coolant to see if you have an obvious head gasket/crack in block/head issue. The next step is to do a pressure test on the cooling system. These are easy and inexpensive to do.
The point I was trying to make... I should have been more clear.... Was that the new owner could potentially buy the car with the changes... And then Ford could over the air update the car and wipe some of the changes.... Leaving the owner scratching his head wondering why certain things didn't...
Oh... interesting that it's sending your modified config back to Ford's servers and that they then must be overwriting their config (tied to your VIN) with your config.
I know this is months later but I was just saw this thread. Quick question: If the car does an automatic firmware update over-the-air, does it overwrite your changes? I don't know how these automatic updates work, but I would presume they are tailored to the VIN... and the VIN will translate...
$170k puts you into GT3/AMG GTR territory and getting very close to 488 territory... all used cars, but an order of magnitude more respect, and all have taken their depreciation hit already. Sayin...
I would be interested to know what the track pack special edition is vs the "regular" track pack.
