Some seems to struggle to get Gold at the All-star w/o a race car. There are also not to many tunes posted so I give it a go.
The ZR-1 RM performance is very close to the real race cars. It enabled me to win Gold at all races with a 2-5 second buffer, all aids off except ABS at 1. Exception is the Nordschleife where I do win Gold with it, but its so easy to crash in one of the many corners.
Strong points with this car/tune
- Easy to drive
- It accelerate great out of medium speed corners (best way to overtake race cars)
- When accelerating it holds its line and doesn't understeer out
- Great breaking and it turns when breaking without losing the rear (ABS at 1)
- High speed turns. You can overtake race cars on the outside
Just to give a hint of the performance. I'm a decent driver but no demon. In the second race I spun in the first thunnel, got into 5th place 6 sec behind the leader. At the end of lap 2 I was back in the lead and won the race with 4 sec.. In the 4th race on the "bridge circle" its about 1 sec faster than race cars.
Fully upgraded the ZR-1 RM gives 905hp att 1100Kg weight. My tune
Downforce: 35/53
Transm.: 360 km/h (380 at Nordschliefe)
Initial torque: 10
Acc sens: 20
Brake sens: 10
Ride h: 5/5 (35/35 at Nordschleife)
Spring: 16.6/14.4
Damp ext 9/7
Damp comp: 9/7
Anti RB: 3/5
Camber: 2/1.5
Toe: 0/-0.30
Brakes: 5/7
I play around with the rear breaks depending on track. Its good at 7 but if I want better turn in use 8, better stability a 6.
I also play around with rear springs. Its pretty balanced but if I want a bit more oversteer lowering the number seems to create overstear (opposite to what I expected)
Its by no means a perfect tune but its good enought to win Gold at All-Star. If someone has an idea to further improve it would be great.
Cheers
