Notes:
I thought this to be a good alternative to Duck's settings, which I believe were designed with a fully maxed out car in mind. It is set up to use only 4 gears so the car can also be B-Specced, if needed, because the A.I. will not shift at a time before power drop off with any more gears unless you make the bottom 2 unusable. 1st gear is only good for those with careful throttle control, so button mashers are better to start off in 2nd gear and let the cars torque pull them out of low revs. As stated in the power numbers, this car is very mildly tuned power wise, so do not try to rev this car past 5500-5750 RPM or you will suffer from mass power loss as the torque drops. The car is neutral until heavily provoked, at which point it oversteers unless you correct with throttle. Throttle oversteer usually only occurs in low-rev 2nd gear corners. The car is quite tossable in quicker interchanges (as evidenced by some runs at SSR5) and is quite docile from 80 MPH up. Top speed is around 175-180 MPH.

*Due to gearing so car can be B-Specced, 5th and 6th gear are more or less unusable (though 5th can be used if it is set to it's highest possible value).

i do have a few suggestions for the suspension setup.

the back springs could be a bit softer. it'll help a bit. and try putting the bound halfway up the scale instead of equal to the rebound.

the car is too low. sports tires can handle low cars but raise the height about 10 mm on both ends.

you'll also benefit from the flexibility of a full-customize LSD.

as for your tranny, i'm not sure how you set it exactly but if you're going for a 4 gear setup don't be afraid to make the last gear as tall as you can afford to.

you'll be in the powerband longer during the straight.

it sounds stupid but this could cut off a noticeable chunk off your time.

i could easily reach 145 mph on the straight by the time i hit the finish line.

my 2 cents.

Your height and bound adjustments are noted, but what do you mean by loosening up the rear will help? With what? Wheelspin?

I'm really not too skilled in the way the Full-Custom lsd works, or what it does, so...

I wanted to do it lowest 4th gear setting, but if I did when I upshifted to 4th it would go too low in the revs and accelerate slower. I was shifting up to 4th around 5500 RPM @ about 115 MPH.

my 2 cents.

Thanks for your input. 👍

 

[dudejo]

loosening the rear is generally accepted as a way to reduce understeer, which this car will inevitably suffer.

as for the tranny, if making the 4th gear tall kills the acceleration then try playing with the other 3 so you don't have to make the 4th one too tall.

old V8 engines are known for making all of their torque low in the rev range so don't make your first gears too narrow.

this should help you make an effective 4 gear setup.

May I comment on the suspension?
Ehm, thanks!
I disagree a bit with dudejo on the rideheight. Of cours it depends on what track you are going to use, and if Midfield is the one, you can at least lower the front 10mm, since this type of car benefits from being a little higher in the rear. Also, the rear is very soft, and can be harder, up to 9.5, but not more. As you use downforce, you must account for spring and damping being compressed at speed, so too soft will make the damping useless (or at least too hard) at high speed. As for damping, a set to 3/6 or/and 4/8 would be better than 7/7.
One thing I agree with dudejo on, is LSD, since the ´Cuda has a rigid rear axle, and no diff at all. The cornering abilities would benefit from a LSD. An estimated set would be around 15/35/40.

My two cents!

 

[dudejo]

except for damping and LSD settings, i tuned the car like i would tune a FWD.

1 question in gt4 physics does downforce increase at speed it seems more like its set for full df at any speed?

As far as I know it increases with speed. It´s not very appearent, but it´s there. I´ve learnt this from countless attempts on 300 mph with a large number of different cars. The faster it goes, the harder the downforce seem to work. And DF does work in low speed aswell, but drag is greater at speed.
Setting up a car to do a wheelie will show you DF increases too. If DF was the same all the time, the wheelie would start straight off the line, but you have to reach at least 250 before you have liftoff, depending on how strong the DF is set, and how much DF that particular car carries.
