If only someone, or Kunos, could concentrate all that info somewhere. I don't have the time and patience to scan all sub forums for stuff I might need to know.
Not so much problems, I'm just tinkering and unsure if everything is alright. Just had a testrun, and my last earo tweaks seem to have made a difference. I can only guess what downforce my car had, sort of 150% of a normal 996 Cup, but as always its hard to find real world values, as in numbers, not "3° more wing = drives better".
Suspension is the same, front is 99% as it was on the real Turbo now, rear axle was Multilink, I fabricated a DWB that sort of works. Spring and Damper values again from 996 Cup cars, but as my car was 200+ kg heavier, and different CoG (due to AWD system), again lots of trail and error.
One guy from the forum tests for me (but has no idea of modding himself), he was faster than Kunos GT3 cars on Spa, but slower on the Nür GP, so I'm sort of heading in the right direction I guess. That was before my last change of aero tho, the one that I just tried to correct...
