I've heard mixed reports of clearance issues with 4" shafts. (I am lowered with Steeda Ultralite springs and have an MGW shifter.) I think I read somewhere that there might be issues if you had people sitting in the back seats. It's true that there is not much room back there but I don't want to have to worry if I do put people back there.

The difference between a shaftmasters 4" AND A Dynotech 3 1/2" is $230. I'm paranoid but I'm also cheap. Should I worry? Is Shaftmasters quality good for the price?

Thanks,
Dino
