You can run the taller(27or28) tires on the Duster by raising the torsion bar adjustments up with the proper wheel offsets
Which limits the front end travel amount upwards
Not sure about the Demon front fenders
So on a car I'm planning on running mid 11's with, what would be more important,
Roll out or front end travel?
I wish the was one easy answer to this question, there isn't
What is good for me may not be what you like the best
Tell us more about your car, class and racing style
Do you like two foot wheelies or two inch wheelies
I use to help a friend race his NHRA 340 Demon stocker E/SA that red lighted a bunch with two foot wheelies with 90/10 front shocks, we put on a set of early Monroe stock 50/50 front shocks that I had and that stop the red lighting and lower the wheelies to 2 to 3 inches on the left front, he hated that and went back to his way
He red lighted on the first round at the Winternationals that year
BTW, I tend to tune for the best reaction times and best 60 ft. times
