I know I have another 3 tenths in me but my foot doesn't seem to agree!
Regarding setups As you can see I'm only D4:Bronze so I am no expert but this is my thoughts for those of you having trouble.
Until you can drive a bunch of consistent mistake free laps there is little point in tweaking the settings except in a very general fashion to get the balance to your liking. For me this is usually a very stiff suspension as I don't deal with weight transfer very well.
Most of the time you can drop the ride height quite a way (in this case all the way) and you shouldn't have any problems.
Personally I then stiffen the springs, dampers and roll bars slightly then go and drive it until I can consistently lap without mistakes.
After that tweak only 1 setting at a time (if you feel you need to) and make sure you do enough laps on the new setting so that your performance averages out the differences in lap times that naturally occur from your driving. The more consistent a driver you are the less laps you'll tend to need.
I am incredibly inconsistent so it usually takes me 20 or so to be sure that any differences are due to the settings and not just my natural extreme variance :/
Finally, I hate this car, I don't like this circuit, but I am really loving my first WRS event
My GT5 is finally fun again. Thanks to those of you who made it possible.
