GT-One shake at 225 mph....

[Inkil]

While I did search for GT-One setups, the 345mph GT-One does not help me in the slightest. Sorry to the author. For some reason the tweaks I have made to my GT-One for it to run on the Super Speedway 150 (endurance race) cause the car to shake badly at 225mph. I have tried to adjust what I know about cars and suspension, but I am a game enthusiast, not a mechanic. If you know how I can fix this, please let me know.

Here are my settings as they sit right now. Perhaps someone can help me get them dialed in so that I can run the race without vibrating my hands to death.

Nitrous: 50 (hardly use)
Turbo: Stage 4
Brake Controller: 16 Front 9 Rear
Spring Rate: 14.8 F/R
Ride Height: 65 F/R
Shock Bound: 8 Front 7 Rear
Rebound: 7 F/R
Camber: 2.0 Front 1.0 Rear
Toe: -1 Front +1 Rear
Stabilizers: 6 F/R
Tires: Hard (R2) F/R
Gear Ratio:
1st: 3.244 2nd: 2.071 3rd: 1.465
4th: 1.090 5th: 0.854 6th: 0.705
Final: 3.769
Downforce: 59 Front 79 Rear
Limited Slip: 10 Initial 55 Acc 15 Dec
ASM Over: 9
ASM Under: 9
TCS: 6

Please let me know what and where I can improve.

Thank you ahead of time.

Who wants to spend a ton of money for a GT series game with real crash damage, and having to spend money to repair it... And the designers dont want to spend years on the code when they can make money now.​

23 people looked.. and no one has any ideas?

I have tried maxing out the downforce, but still get bad shake in stearing.. almost like its trying to take flight... steering gets loose and twitchy at 225mph...

setup hasnt changed much except the downforce...

I guess if by morning if no one has wrote anything, I'll chock it up to probably not getting any response.

i haven't found anything to make that go away either. i do find however, that it makes driving this untameable beast at 300+ on the le sarth II track extremley fun. besides, a car going that fast isn't going to handle that smooth anyway. not unless you got the bat mobile. wouldn't that be a sick car? gt5?

Try reducing the bound, bring it down to like 4 or 5, that way your shocks will be more effective. The car will absorb the bumps rather than bouncing over them.

Well, no matter how well you tune your car, you're going to feel the road going 225 miles an hour. The game is realistic, and in the real world, you feel the road/track when you exceed 160-170 mph. Besides, I like it when the wheel jitters. makes it more enjoyable actually having to drive your car, just like in the real world.

Don't have the car yet to try anything out firsthand, but having just read this:

it looks like your TOE settings might be suspect... Try a run with zero toe on the front and a touch of rear toe OUT. Let us know how it goes.

If you bought the black used GT-One, make sure you take it into the shop for a rigidity refreshment.

I ran mine without it right after I got it, and it seemed fine at lower speeds, but it was all over the place at the top end. Fixing the rigidity did wonders.

As previously mentioned, I'd put more rebound damping in both front and rear shocks, keeping the ratio proper, example 2 bound with 4 rebound, 3 bound with 6 rebound, 4 and 8, something similar to that. Pick up any racing shock and you'll see that the rebound is stiffer. If u wanna do a little NASCAR experiment, max out the rebound damping and see if u go faster on the hi speed oval. The nascar boys did this to keep the rear of the car from coming up after coming out of a turn, so much so that it kept the spoiler out of the wind for most of the straights. Nascar has since made a rule outlawing this, and they now check shock valving along with the myriad of other things they check on super speedways.
I'd also make the toe zero for the front, and something between 0 and .5 toe IN for the back.

Thank you "G"

I'd also consider raising the ride height to something higher then 65mm... thats incredibly low!

Well, wouldn't you shake if you were going at 225 mph?

 

[slipknot10wa123]

Toe and Camber off, since you are straight lining, anything else will just have less contact patches with the road.

I was encoutering the same thing with my Black LM GT 390 last night. Try reducing the downforce.

 

[Pink_the_Floyd]

I run a 1158 bhp GT-one to without any problems, the only problem is:

Test this:

Replace all the turbo's and stuff back to stock until you got a GT-one stock how you bought it.
Now go to the La Sarthe circuit and let your B-spec. driver do a couple of laps.

Noticed it?

On the straights it cannot go faster then 310km/h because of the shaking while in A-spec. I can get over 360km/h with a stock GT-one.

Anyone got a solution for this??



Cheers,

well as this game is a driving simulator i would expect a car to shake at such high speeds on this game. You would expect a toyota gt-one car to shake when going at say 220mph in real life wouldn't you? so i would say that this is just one of GT4's many driving realism's.

ive been in a ferrari once and that shook at around 200mph when i went to this thing for my 35th birthday.

Could be but I watch Le Mans 24 hours every year and in real they don't shake so much.

But please help me to solve my B-spec. problem 👍
