Tuning Mistakes in "Ultimate Car Guide"?

[alfredchiwai]

I found that table in p.167 about the suspension settings for technical courses contradicts what were written in p. 157. I think shock absorber(Compression) should be weak for front and strong for rear, while the spring rate should be weak at front and hard at rear. Am I right?
I am a newbie of tweaking cars. I don't know whether I am right or not. If I am wrong, please kindly teach me why the settings is needed in page 165. Thanks!

No one knows?

The spring rate is almost exclusively higher in front than rear.

I wonder how well modeled this is. I know that in my IRL Car, the rears should be stiffer then the fronts due to the motion ratio being in the 0.6 - 0.8 area, which means that your spring rate of 10k KG is a 6k - 8k KG wheel rate, which is what you're after. Wheel rates should be harder in the front, but since wheel rate =/= spring rate, you have to think about what you're actually going to set it as.

At least in real life .

Wrong knowledge in the table of p.167? Is that correct?

The spring rate is almost exclusively higher in front than rear.

Not in a rear engine, mid engine, or in a car with massive rear downforce.

Jaedon, it came with the Collector's and Signature editions.

It looks right to me. All the suspension modifications listed in that table have the effect of giving the rear end of the car more grip, which does decrease oversteer.

This man speaks the truth.

Click on the link in my signature for a nice set of free (GT Planet) tuning guides.

The first of which covers suspension and brake tuning, they were written for GT4, but are fine for GT5.
