I do not believe "tips" on tunning will help you a lot. That's why we don't have a thread about it, because in order to succesfully tune up a car, you have to understand the physics laws of GT4. Many tunning guides have been provided from great tunners to teach us how to properly tune-up a car. And eventhough each one of us has a different driving style, giving a shallow "tip" like "lower the height ride" would be useless if we don't consider spring rate, camber, damper...etc. Plus you have to analize the car AND the track before tunning it. Not every advice is correct for every car.
Example: On the Nurburgring Nordschleife, you need a soft suspension to get around well....on other tracks, like Circuit de la Sarthe, you would need a stiffer one and obviously modify the transmition gear ratios.
Even a pocket guide for tunning suspension for GT4 has been given by //M-Spec on the stickies for those who don't want to read the complete tunning guide by Scaff which is great, and is not full of fancy words, Scaff wrote it so members whose english is not their first language, don't have major problems understanding it.
The only tip I can think of that can be applied to every car would be NO Drivig aids or ASM. You can use TCS on some cars, but i really recommend turning off the ASM feature.
That's all, and trust me, a lot of members have been wanting this from the release of GT3. But that's what makes the game so great, the fact that you have to learn how physics (that are close to a real life) work in GT4.
Ciao!
