Here are all of my GH1 setups in one zip file. These are my older GPL setups, which I made during 1998-2000. They are a bit easier to drive than my newer "GH2" setups, but still fast enough. The difference at most tracks with GH1 and GH2 setups is only a couple of tenths. So if you're a beginner with GPL, give these setups a go.

The reason these setups are easier to drive is because of the differential settings. The car is stable under braking and turning in, and also a little bit easier accelerating out of the corners compared to GH2 setups.
