Hey guys !
I tested the cars a bit (setting only the gearboxes a little) on my usual testing track, Barcelona moto layout.
I can go with the Surtees TS16 if it's ok. I love its "Natural orgasms" flank advertising. No, sorry, it's "National organs".
Anyway.
Tyrrell P34 : Nice for her exotism, but a weird feeling of understeering (potentially well represented). This car didn't take part in 75, so I guess it would be better not to pick her. Also I suppose that AC graphic and physic engines can't properly handle such a 6 wheels car : if you block the front wheels, only 2 will do. Probably the other 2 aren't even braking.
Ferrari 312T : Looks like the default setting is terrible in my hands. Can't get her in her supposed pace like that. A tad oversteering at entry, definitely understeering at exit. And not so stable while braking.
Lotus 72E : Delightful. Probably a large room for improvements, but quite efficient yet. And that sound..
March 751 : Nice, quite well balanced.
McLaren M23 : Nice, quite well balanced. Efficient.
Surtees TS16 : Very gentle, well balanced, maybe the worst weight/power ratio, but like her.
I may have tested other ones, but can't remember well..
