Not sure if I should start a new thread for this, but seeing as we've been discussing the NSX in here and I haven't checked this on another car yet I'll post here
When I 1st started running the NSX on Friday night I didn't have the rear wing fitted. I'd removed it post my last run for aesthetic reasons... I'm not generally a fan of the way the cars look with the rear wings fitted, so I don't usually fit one.
Anyhow, I was running against my previous ghost, and despite no downforce I had no more straight line speed. Not so surprising as GT games don't seem to penalise your speed severely for running a wing.
What was surprising was that the car seemed to have less front end grip... the wing on the NSX should only be adding rear downforce, and the car has 0 front DF with or without the front add on aero. The car should have oversteered more, yet it didn't... it understeered.
More strange goings on with the physics model!
