Best Of 5

[VdubVR6]

So I did a little testing to see if the settings I made for a template would work for a larger range. This is what I came up with

Race Spec
Spring Rate: +2.0 Front +2.0 Rear (Added To Stock)
Ride Height: 10 mm from slammed Front and Rear.
Shock(Bound) 3 front 6 rear
Shock(Rebound) 6 front 8 rear
Chamber: 0.0 Front 0.0 Rear
Toe: N/A
Stabilizers: 5 front 5 rear
Limited Slip: Initial Torque 15
Acceleration 45
Deceleration 30

Trans: Use Preset 17.
Driving Ads: Remains
Race Tires : Med
Nitrous: Max Power.

Port And Polish, Balanced Engine.
Race Exhaust.
Racing Chip
Racing Brakes W/ Controller
Racing Suspension
Racing Trans
Racing Clutch, flywheel and drive shaft
Limited Slip Racing Spec

Now given that some of the cars where AWD I had to reset the Variable Diff to a 50/50 so you will have the buy this for AWD cars.
On The first runs The setups were like the top says besides the Trans which was a stock first. Also I used the Stage 1 N/A and stage 1 Turbo for those that used them. For the Turbo cars I gave a Race Spec Intercooler. I turned the Nos off for the first stage only so I wouldn't push it.

These Are the Cars with the {First round Setup}
Model Power Time1/4

96 3000GT VR4 439hp 11.9

97 Supra RZ 442hp 12.2

96 Skyline GT-R Vspec 445hp 11.3

00 Z06 Vett 502hp 11.1

00 Mustang SVT R 491hp 11.4

After the first round I placed the Vett as the leader, But this was about to change thanks to some needed power gains.

In Round two I put stage 5 or 4 turbos and stage 3 N/A Racing Trans with the preset of 17. All cars are set the same way besides the power levels between them.

Round Two.

Model Power Time1/4

96 3000GT VR4 835hp 9.1

97 Supra RZ 844hp 10.1

96 Skyline GT-R Vspec 754hp 9.1

00 Z06 Vett 740hp 10.1

00 Mustang SVT R 616hp 10.6

After the number rolled in. The 3000GT was now leader, but the numbers were very close given the power and drive trains of the cars. But now its Top Speed time. Using the preset 17 I ran a top speed.

Top Speed

Model Top Speed

96 3000GT VR4 225.14

97 Supra RZ 221.00

96 Skyline GT-R Vspec 209.70

00 Z06 Vett 227.72

00 Mustang SVT R 221.00

Give that the preset 17 used is limited to the gears for each car. The overall scores where nice. I'll use this set up on other cars for short tracks but for long tracks I'll used a diff set up.

Overall
1st 3000GT
2nd Z06 Vett
3rd Skyline
4th SVT R Mustang
5th Supra

Close Race.

Comments Are Welcome.

Oh yeah. Looks good. But doesn't really tell a thing.

You made a ton of testing just to find out that the highest powered car with the best grip has the best acceleration? Way to go, who could have guessed?

I wish you tried that setup platform out in track driving. Sorry to say, but it's hopeless. For most car & track combinations the springs are way too hard, the cars way too low, the lack of camber destroys cornering grip and the differential makes the cars reluctant to turn, not to mention the outright stupid VCD settings that only add to the understeer. And the driving aids cripple what's left. Combined to this are very long gear ratios together with poor low end torque thanks to the high tuning levels.

The conclusion: high power doesn't mix well with poor suspension setup in other conditions than on the drag strip. A well tuned 500 bhp car will slaughter your setups around a balanced course. Call me rude, but this is the truth. Use it to your advantage. 👍

I've got to agree with Greycap here, attempting to use a template of this nature just doesn't work.

What suits a 500 kilo lightweight RWD car will not suit a 1500 kilos RWD car, hell what suits a 500 kilo car on one track will not always work for the same car on a different track.

Spring, damper and stabiliser settings are all load dependant, a spring setting of 10 may suit a 1,500 kilo car around a smooth track, but around the same track with a 500 kilo car they would feel far to stiff and in a 2,000 kilo truck could even feel to soft.

Generic setting like this just don't work (in reality or GT4).

I would also have to raise issue with the lack of any camber settings, zero camber may be fine if you are only interested in getting down a straight line quickly, but the second you throw in corners its a different story. Here camber is a highly valuable tool and a setting of zero front and back is almost certainly going to result in a slower lap time.


I pretty much subscribe to the view that you have to drive a car stock and then look at its inherent characteristics, once you have that you have a starting point for tuning to get the best out of it. I find this approach allows you to minimise a cars weak areas and maximise its strengths.

If you want to see an example of what I am talking about take a look at the two tuning guides I put together (see the thread at the top of this sub-forum or follow the link in my signature), both of them contain an example of a tune. It clearly shows the approach I personally take to tuning.
