dont waste your time, yes it might be a touch lighter, but driving around with no more than 1/4 tank will have the same effect.. it really isnt worth the hassle unless theres good reason, your just making work for yourself and then you have to put it all back to sell it... most of its in your mind..
ive had my gtt stripped and there was little difference if any at all.. if i was at the pod/track trying to take off a tenth on a second or two then i'd do it.. running on a 1,4 tank is what i tend to do, but guess your seats are a touch heavier than mine, but id still like the option of nailing a bird in the back on a comphy seat..
your p155ing in the wind if you ask me
