^^^ Im afraid you have the Toe values confused... In GT Toe in gives you straight line stability and Toe out gives you more control while turning on the front tires for this case....

It adds a chunk of maybe 25-30 hp, well worth doing. Do it at any time, tbh, I've always noticed a difference.

well you do it it the first time for the "glitch"
then again after the motor is broken in for even more HP
Mine is sitting at 868HP

The repair? No... I'll post my setup by Friday, I'm close to a good one

No I mean in the tune shop... Rigidity improvement on new cars is not a good thing to do in my experience...
 
i think this car handles fairly well, the problem im having with it is under acceleration the nose lifts and causes the outside front tire to lose grip and understeer. controlling the throttle helps, but is there a specific area to focus on to tune this issue out a bit? or is the car simply too powerful to suppress the nose in this case?
 
Hm I use these:

Aerodynamics: R 20
Transmission: Top Speed 230
LSD: Initial F 10 R 15
Accel F 25 R 40
Braking F 20 R 20
Torqur Diff: F 30 R 70
Suspension: Ride Height F -17 R -10
Springs F 16 R 10.5
Damp(Ext) F 7 R 5
Damp(Comp) F 7 R 5
Sway Bars F 3 R 3
Camber F 1.2 R 1.0
Toe F 0.00 R 0.20
Brake Balance F 5 R 6

It handels nice ;) You can go full speed into a corner and when you brake the back end slides just a little bit to help cornering... It could still be improved :)
 
Didnt have time last night to post settings... was out all evening.. I will post tonight! For sure! 👍

Changed the Torque distrbution to 20/80, set Toe on 0.20 in the rear, and I like my cars "break with front" so Break Balance goes F6 R5 for me.
Now this car oficially is a beast. Huge thanks to the creator of those settings
 
Hey all!!

Thanks to everyone that is using my setup for this car.
I would have to say its a real B**ch to tune but i
have a new setup that i want folks to try.
After hours of test runs i believe ive come up with
some settings much better than the ones in my last post.
Just a couple things....

1) ive found that "not" transfering the majority of the torque
to the rear of this thing solves alot of issues. 40/60 is ideal
because i found that the front wheels actually work to "pull"
the car into the inside.

2) setting the LSD properly is crucial.

ok so enough babbling, here they are......

Aero 7 why?.... downforce in the rear causes understeer

Trans 242 top speed

LSD:
Initial 10/10
Accel 30/20
Braking 15/55

Torque Diff 40/60

Suspension:
Ride height -15/-10
Springs 13.5/14.5 why stiffer in the rear?.....it may sound funny but if you read the manual in the suspension section it says stiffer rear generates oversteer.....i thought they were kidding but apparently not...lolzzz!!!
Dampers(Ext) 6/6
Dampers(Comp) 5/5
Sway bars 2/2
Camber 2.0/0.5
Toe -0.10/-0.35

Brake Balance 4/6

There it is. Have fun. let me know how it goes. and feel free to make
your own tweaks to this.

I have my 07 GTR stiffer in the rear also decreases oversteer. I also have my torque diff set at 20/80.

Why don't you try 2/3 for the anti-roll bars instead of increasing the rear suspension. In real life this would be better anyway, as swaybars only decrease body roll in corners where spring rate affects many other things. Stronger anti-roll bars at the rear will definitely induce oversteer.
 
This may sound crazy but I put my ride height all most all the way up and softened the spring all the way. This car is never gonna be fast at Nurburgring but its decent at other tracks.
 
I want more info on this haha. Been loving my GTR but its been understreering like crazy.

Going to try this tune after work but in the meantime... Bump~

Any luck? It's been a few nights already.

:lol: Thanks for the headsup.

For some reason I've had a crapload of people asking me for the GTR Spec-V tune.. Ive been quite busy grinding away at GT so please accept my apologies for not posting anything yet. The tune I have is made with a wheel and tuned on the Nurburgring Nordschleife. Its running Sports Soft tires, up 'til now Ive managed a 6.58,xxx with it and since I know Im not the fastest out there I bet it could do it a bit quicker with someone else behind the wheel.

I left a hint of understeer on it on purpose and the beautiful thing about it is if I notice it is going to understeer I turn the wheel a just a tad more and bam, it bites into the corner no problem. The only thing to really keep in mind is the braking distances. This thing gets up to speed very fast and still weighs a crapload even though its been on diet. ;) Anyway, no more blabbing... I'll be leaving work in about an hour or so and I'll make sure I post the settings this time... then you can all make up your own mind if it handles properly or not. 👍

Ununpentium settings were about 1.5 secs faster for me than blitz at high speed ring with med racing tires.. may be due to high speed and downforce...

My settings are 'Ring specfic ;) Can't recall which other circuits it ran decent at... Think Tsukuba as well... 👍
 
What settings do I use if I want some casual drift in corners

Because most of the time in races you either are over powered and make a huge lead or under powered and you really have to brake late ect

But when your over powered I want to mess about drifting around corners

If that were true, then GT5 must be have poor physics (which I doubt). A GTR should be able to out perform a Porsche on the 'ring, I believe there's lots of untapped potential in the chassis and what have you.

DON'T GIVE UP!

I like this tune but wanted to know how can I get a little more oversteer in this tune?
