I think it depends greatly on the inclination of the back part of the seat...basically personal preference. If you have it straight up and down you will hit the roof, if you have it laid straight back of course you wont. I have the seat mod on the drivers side and I must say at 6ft I like the drivers seat much more than the passenger seat. I would definately check it out before you commit to it, however if you truely love the vx, mods are available for just about everything.
