I wouldn't cut the fronts. They are longer because they are built to squat and store spring energy to send the front end up hard on launch. If you cut them you reduce the effect of the spring. A 90/10 strut will enhance the spring big time and let the front end stretch out all the way on launch puting the weight on the back tires.
I just left them alone and faught them four hours trying to get the fronts in there. If the front end sits higer put a taler tire out back because you want more sidewall anyway. IMO use the 90/10 strut even if you drive it on the street, I did and it was fine.
