I'm sorry. Wut? That NSX and it's other RKM counterparts are renown for its handling. They have been, along with…just about every setup on competitive tyres ever posted here, running over 2.0 or 2.0 camber for donkeys years with positive effects on the cars grip.
The fact that it can't turn could be, and here comes a revolutionary thought for you, your driving style. I mean…I'm not the greatest driver, by any lengths, and I can still get that NSX to victory in 550PP rooms at Spa without any, any, of the issues you state.
And may I take a guess…the corner where the NSX refuses to turn is Eu Rouge? If so…slow the bloody hell down, the car doesn't have front downforce to give it the grip for that bit at full throttle, and the best you could do is just lift a bit, let the car readjust and then gun it. Everywhere else though…well, last bit of help.
Try this version. If you fail to like this one, then I'm sorry, you're just not normal.
