DiRT Rally DiRT Rally - setting up T3PA clutch

[Davy Jones]

I own T300 set with T3PA pedals & TH8A shifter. I haven't played DR for a while and now trying H-pattern + clutch for the first time. Use of clutch does not seem as smooth as in e.g. AC or RaceRoom. I've been playing around with clutch saturation and deadzone settings. Still not optimal though. I should note that I'm trying Group B Quattro so I dont know if the issue is specific to that era or something.

Wondering am I doing something wrong or is it an issue with the title in general or Group B era cars.
