Since I bought GT4 I have been putting together notes, test and other information regarding GT4 tuning. Particularly in the areas of Suspension and Brakes, some of this has been posted here at GTP. I have also been writing up my notes so that I had a useable and readable guide to suspension and brake tuning, and in the spirit of Christmas, here is my present to all my fellow GTP members. Scaff's Suspension and Brake set-up guide. .....its around 2.1 meg so should not take long to download. GT4 Downforce, LSD and Gear Ratio Tuning Guide, size is 1.6meg and its .pdf format. Edited 5/2/09 - Download the guides from here now - click to open post in GT5 sub-forum OK I've now finished the second part of the GT4 tuning guide, which covers Downforce, Differential and Gear Ratio tuning. Enjoy I hope you all enjoy it and find it useful. Regards Scaff BTW - I am more than aware of the threads regarding the possability that suspension tuning is backwards in GT4. My views on this subject are generally well known and are covered in guide. Please remember I originally wrote this for myself, if you disagree with the fundimentals of the guide, then put pen to paper and write your own.
