You'll have to be near perfect through every corner & will probably need a very quick car.
I had to build up my E30 M3 just to keep up, and he'd still pull away from me on the straights. However, he brakes extremely early & takes corners somewhat slow, so a relatively quick, well handling car should be able to catch up. Unfortunately, the next 2 race (Enna & Zolder, I think) are much quicker, and he will blast away.
On Enna, he was wrecked so I was able to win through his DNF. On Zolder, I could only catch up on the back half and eventually had to hold him off during the final lap.
Suzuka, he beat me flat out; I just couldn't keep up once we hit the straights.
