Historic Racing Car Cup

Anyone have a suggestion on how to set up the '74 Countach for this race? The one I have is completely tuned...maximum horsepower, minimum weight, all the top drivetrain parts (clutch, flywheel, fully adjustable tranny, etc.), racing tires.

All the bells and whistles on this car...but I have only managed to finish 2nd in both Cote d' Azur and Deep Forest after many attempts. I have noticed that I can get out in front if the Toyota 7 is not in the pole position to start, and I can cause a pile-up on the first turn and scoot around the other cars...basically I retire and re-enter until I get the most favorable lineup (the toyota as far back from the front as possible), then just do the quick restart (takes you to the beginning of the race with the same cars without going to the main screen) until I can get out in front after turn one. I have that part down...my problem is holding off the Toyota 7...I can keep ahead of him for like 2-3 laps, then my tires crap out on me and start smoking, the car starts to handle like crap, and I get passed.

Is there any setting for a fully-suped Countach for downforce, shocks, ride height, camber/toe, top speed, etc. that anyone has found is ideal for these races? I have played around with all of these but still cannot find the ideal setting.

Any suggestions are much appreciated...this race is driving me crazy!!!
