Give this a shot. It's not quite fully tuned (731 hp/1230 kg) and the only aero I'm running is the rear diffuser. It tends to rotate a bit under trail braking, if you do it right you can pull off some nice smooth drifts. If the balance isn't to your liking I suggest changing the torque split and anti-roll bars. I tune using a controller.
I dont have this problem. I'll post my tune later on. I don't run with the full power though, I run it at 650+hp, nowhere near the 700hp mark though. It's easier to set your car up while its lower and then go from there.
Mine too. I only did engine tuning stage 1 and skipped the the hood and windows, but I won the Lamborghini event easily. Now I just need to find the right shade of lime green to paint it.
