i have the flaming river setup on my fox. i would definately do it again. the one thing i would do different when buying my parts though is i would just buy the rack and tierod ends from flaming river and then i would get the steering shaft from maximum motorsports. If I remember right the cost is pretty close but the flaming river steering shaft is kind of ghetto the way you need to put it together. the maximum one is all welded up nice with a telescoping shaft.
If i am being completely honest when i first drove the car after the switch I thought i had made a mistake. But after about 500 or 1000 miles I feel like it got much easier to turn. I also don't drive in the city and parking is almost never a problem with me. I put about 4000 miles on the car a year so it isn't a daily, but i only drive 12-15000 a year anyways so it is a good chunk of my driving. now when I switch between my regular car and stang I can barely tell a difference. I think it has alot to do with timing also, as long as you wait for the car to roll for a split second before turning the wheel your good.
