FWIW i removed my rear seats recently for a whole tank and it made no difference. That said, i was P&Ging it and probably not too well either. Anyway, if it was going to make a difference it would have shown up. It accelerated quicker but also decelerated quicker too, due to the weight reduction i suppose.
If it was me Eddles, i wouldn't bother with too much weight reduction. Too much hassle for too little (or no) gain.
Relocating the air inlet might make a difference worth talking about. I have yet to relocate mine but i have stuck on reflective foil on the intercooler duct and the entire intake pipe, along with a cold air intake baffle that gets air from the gap above the headlight. Not perfect but no major savings either. A direct feed to the intake may give me something so i have to look into that when i get the time.....
