For the Cadillac use a Bugatti Setup.
The bugatti Veyron problem is that it spins or it is pushed to the barrier in both corners of the track. The Cien turns and handles 3 (or more) times better than the Veyron, so adapting a TOP Speed Veyron Tune it will be the best idea and It is supposed that you wont have any problem in the corners.
BASIC SETUP
Suspension:
rh: MAX/MIN (If it's hard to turn, try lowering the front)
spring: MIN / Near Max (Rear depends on you)
Damp Ext: 2/8
Damp Cmp: 2/8
Bars: 1/1
Camber: 0/0
Toe: 0/0
Transmission:
1. Predet
2. Lower the Final (until 510km/h appears in the top)
3. Lower your last gear (6th or 7th) until 550km/h appears in the top.
Good luck!
