What can I say... Car looks fantastic, and tires looks very realistic. But how it drives? Well, I understand why they are not a top F1 team, so to speak

But I think it could be fun to drive if not:
But I cannot understand what's up with ALL ISI's modern openwheelers and brakes locking (especially when track is green and tires cold). First time I got out of pit with this car at malaysia, I headed for first corner at medium speed and was thinking
Now I'm gonna brake eeextremely easy because this car will surely lock tires easily. Because I use Trackmap plugin I can see how much throttle and brake I'm applying. And I'm trying to brake easy for first corner and look at the brake "indicator", and see that I'm not using more than 10-20% of the pedal when the brakes are locking up and tires creating a big cloud of smoke! I try again at very low speed to apply 10% brake, and the tires are locking up again (I'm talking about less than 50 km/h...). I had even decreased brake pressure to 92%.
I don't get it

It's the same thing with all the open wheelers for me, and have beens since day 1. It's getting much better when track gets rubbered but still... And I have NO problem with 60's F1, Corvette, Nissans etc etc. Only the modern openwheelers. Why? I'm using G27 (but it should not matter, because I have no problem with other cars, as I said).
But thanks for the car anyway
