Okay so I bought the Ford GT brand new. At first I suped it up with all available upgrades, including the NA Stage 3 tune-up. Then I tuned it and took it for a spin on the track, and to my chagrin it was almost impossible to handle. So I downgraded all the way back to NA Stage 1 and adjusted numerous settings, and still I can't get the car to drive like the dream it's supposed to be.

Here are the problems:

1. First of all, the car vibrates rapidly, left and right, while driving. It's a shaky ride and I can't seem to get the car to stay in a straight line.

2. During acceleration and braking, the tires struggle to catch a grip. The squeals are rapid, almost like a machine-gun burst. Again, this adds to the problem of trying to drive straight.

3. When I brake to enter a turn from a high speed, the car spins out violently.

I can't seem to find the problem. So what I need is someone who both has this car and knows how to tune the crap out of it. It's my favourite car next to the RUF BTR, so I'd like to be able to drive it!
 
Thanks a lot. If you're not going to post anything intelligent, informative, or insightful, get lost.

It's a supercar. It was built to go fast.
 
It has medium (R3) racing tires and no, I haven't tried fiddling with the ASM and TCS, the car is unstable enough as it is!!
 
It sounds like you've got typical drifting settings on the car. Both ASM and TCS at high levels should help and you should even buy a soft type of tyres for it.

Hmm...can you get it close to stock as possible and get the grippiest tires available?
 
💡

Maybe Kaz-san modeled one of the versions pre-recall?

:lol:

Did you drive it before you tested it? If so I'm assuming it didn't do it there. Sounds like maybe a downforce issue?
 
1)try softening the front suspension dampening and maybe spring rates. Sounds like you lack front end grip at speed
2) Stickier tires? More TCS? For braking...are the fronts or rears locking up? Adjust brake bias from front to rear, or rear to front..and weaken the brake bias if the wheels lock up too easily
3) Dont trail brake so heavily..brake in a straight line..then turn...do you still swap ends? What is your alignment at?
 
Get the full suspension package and tune it for a little understeer.
About 2.7 degrees in front and about 3 in back and try that.
 
Ps, you get rapid tyre squeels on braking with slicks and when you've upped the settings (im assuming it's increasing the level of abs) on the brake controller. Also using too high a value has a negative effect on braking, well that what it seems to me anyway.

Personally I don't like to use ASM or TCS (ok, maybe level 1 for easier launch) to help tuning the car.

Anderton: List out the setting you have, it's easier to identify what needed to be adjusted.
 
I haven't delved that deep into the game, but if you can adjust the gear ratios (I'm sure you can, because it was a feature of all previous GT's) I would say lengthen them up (tune for top speed). If I had a rear wheel drive car that hit real hard and struggled for traction, this always helped. I've used this on the old Viper LM and TVR cars that would spin out at the slightest provocation.

Conversely, I have tuned many an AWD car to the brink of traction with gearing, even to the point of several of them shaking violently while going around the track under any type of acceleration, including straightaways.

Regardless that car is one of my favorites so I'll acquire it shortly and keep an eye on this thread. I'll post my results after messing with it some.
 
I've driven the GT in GT4 - and my initial thought was - Holy Cow - PD and / or Ford fubar'ed my belowed GT40 from GT3....

Until I realised just HOW fast I was going...

He does sport a point there... It is better to find the exact problem other than to start curing randomely.

Is it that wierd when it's tuned? I haven't bought one, so I wouldn't know. Or was it stock?

I haven't bothered with tuning yet (chinese version and all).. The car is awfully fast bone stock...

Then again - It's probably just me being slow...
 
Ford GT does seem real hard to drive to me, too.. Especially the braking. I can't get it to brake right, it might just be that I'm still trying to play it like it's GT3. I can't wait til there's some decent tuners posting setups so I can see where I'm going wrong :P
 
Apparantly the new GT's are pretty squirly in real life as well. I read the Top Gear review of the concept model, and they also thought the handling was pretty unpredictable. However, he also said that the problems could be fixed with proper tuning so it should be possible to get it under control in the game with enough tweaking.
 
I hear you about the braking - a good test area for me is the first corner of Grand Valley, as you have to brake left slightly which can get the tail out. I worked on the settings about a month ago which reduced the understeer, but this made it sensitive under braking. Maybe an LSD might help you, or setting the brake bias slightly more stronger at the front.
 
what ive found is that, on my s14, between 68-80mph the car rumbles just as you have described. I changed the oil and rims and it seems to have gone away. You might try putting a roll cage in it.
 
Did you use Light Weight 1, 2, and 3 on the car? If so I would say sell the car and definitely don't do that again. For now you can trying adding ballast and see what you can get with that.
 
Yes I did all three weight reductions and added a rollcage. Why shouldn't I have done that? So you're saying I should sell the thing and buy another one?
 
From what you said it your first post, that means that sliding during acceleration is now in...I think it's called torque steer...Nice!

But as far as your question goes, well if the probleme is weigth transfer then lighten the back, put softer springs on the back so more weigth go on the driving wheels so more traction is available.

Torque steer is basically what happens to a front wheel drive car when it has significant power. The car transfers power from one side to the other, and the car exhibits a pull toward the curb and/or toward the center line (left and right).

Sliding during acceleration is exactly that... powersliding.

Little turbo civics are crazy with torque steer sometimes, but are for the most part, incapable of powersliding.
 
car is too light for the power and torque I think now that's why you've got problems.
Looks like GT4 is quite realistic concerning lightweights and power

That's got to be too-stiff a suspension. The wheels aren't rebounding to stay in contact w/ the pavement, so you're intermittently airborne over tiny undulations in the road. Soften it way up, then stiffen incrementally, testing as you go.

Yep
 
Thanks everyone for your help...I think after all is said and done, this is going to be one of those nearly impossible cars to drive. But nevertheless, I'll try what you've all recommended.
