Your clutch pedal pressure will all depend on what clutch you get, when you talk to the person you purchase it through they will go into more detail, if you will be pulling I would recommend a heavier plate load which will make the pedal pressure more stiff, but thats something you will have to deal with if you want it to hold. For drag racing only you could get by with a lighter one like a 3250 and they are not to much worse than a single. I have ran about everyone you can get and currently have a 3600 in my 04 and love it and the pedal is not to bad and i have a 3850 in my 06 and i got used to it pretty quick
