355 v 993 T4.

Went out for a hard run with two of my mates one in his 360 coupe and one in his 993 T4. Bloody hell them 993s do take the corners well. On the long straights he was just edging ahead but not enough to leave me as such, but in the corners he seemed more planted. I know the 993s are 4wd but...
Any way has anyone who has had race track experience ever keept with the 993 T4 or indeed had the better of one. My 355 did very well against it and my mate said that when i took the lead he was struggling to stay with ME.
Any expereances here?? Have i let the 355 down by loosing my nerve on extremely fast and hard bends? Imput from racers maybe.
