So, I traded my 07 is350 for a 14 is350 f sport awd yesterday. I am a big guy, 6 foot and 300 lb, and I have noticed the sides of these sport seats squeeze my kidneys pretty good, to a point of discomfort in very little time. Is there any way to adjust the side width? Or do they break in over time? Any suggestions (besides put down the cake, I'm working on it)?

No adjustments for the IS Fsport seats. The only car I know of that has these adjustments is the GS Fsport.

Can't guarantee they will break-in further tho. Since the car is already been used. But who know! Give it a try.

even after breaking them in, they only get slightly better, your best bet is swap the GS350 F sport seats into your car. The bolsters are adjustable on the GS f sport.

Good luck

Has anyone tried that to know if they fit? GS seats are amazing but WAY bigger than IS seats.

I'd be interested to see the seat swap.

sorry bud, your pretty glue to it now, just break them in and see what happens...

There is no way to adjust the width....
The IS is a compact sport sedan, so it's gonna be tight for a big tall guy like you, unfortunately.
Maybe go for a GS?
