Are there any adjustments that can be made to power seat assembly/track so the seat can go back further?

 

not really , unless you have a fabrication shop that can weld you a new frame that the seat mounts further back on. Remember, there are four bolts holding the seat to the floor. No matter what you do, the bracket would have to still line up with those or it would be too unsafe to drive.

 

How far back you need it? I'm 6'3" and it goes back far enough. Im in Charlotte, what part of south carolina?

 

About 70 miles south of you on I-85 in the mega metropolis of Spartanburg... home of BMW Manufacturing... another reason not to buy a Beamer

I'm 6'5'' and a few more inches of leg room would be great.
