Well here's a tune, but you're not going to get rid of the FFB shake. Trust me, it was going crazy for me as well on Nordschleife.
I always tune my cars first for Nürburgring GP/D, and then test them on Nordschelife. I've changed the oil in this car, and broken it in just a bit as well. It might go a little higher still, but for now here are the specs:
Ferrari F10 '10
716 hp
560kg
And here's my setup:
Aero: 127/175
LSD: 9/36/17
Height: (not adjustable)
Springs: 15.8/15.9
Ext: 7/8
Com: 7/8
Roll: 6/7
Camber: -3.2/-1.2
Toe: -0.55/0.53
Brakes: 8/2
There is so much room for variation with this car that you could tweak it to infinity. But I feel that the stock setup is very solid already, and most of how well these cars will perform weighs with the driver.
I ran this car for several laps on Nürburgring GP/D, with an average lap time in the high 1:08's. Fastest lap was 1:08:212, with a trans. setting of 199 mph.
I also took a couple of very conservative laps on Nordschelife. My fastest time was 5:25:167, with the trans. set at 217 mph (default). Don't go any lower or you will max the rev limiter on the long straight. I'm quite sure this car is capable of a 5:20 time on that track, probably in the 5-teen range as well.
Enjoy the tune, hope it helps.
