I am 6"3 230lbs have re drilled the seat and moved the tracks forward about 1.25 inch so you still use the stock holes in the floor. I can completely stretch out now very nice to drive not cramped up any more I have done this to all my ebodies my wife is 5"2 seat still goes far enough forward for her,only thing is you have to remove or mod the plastic piece on the l/s seat belt. I drive my cars all the time so comfort is a big factor. You may want to shim the rear studs for the most comfortable spot .It takes me about 1-2 hours to do. all you need is some 5/16 bolts & nuts 5/16 drill bit & washers.
