Quick weight loss for street 86.
Take everything out of the boot.
Take the back seats out, they're pointless anyway. The brackets and seatbelt receivers are just sitting there too, pull them out.
Pop the 3rd brake light out.
Leave the cover on the parcel tray. Looks like crap over wise and it weighs nothing. Leave rear side panels as well, no weight there. If you do take them out though, you'll also be able to get to rear belts. I didn't though, as that panel is joined to other panels around b pillar.
Rear mats as well, don't need them.
Under hood, boxer cover thing on manifold. Take bumper off, do you need the driving lights? Pull them out. Bumper beam, don't need that. Window washer bottle, just wash window when you put petrol in.
Do you need air con? Car is pretty cool with windows down and fan on. Pull that out too. The condenser, hoses, hear exchanger at the front. You'll need the JDM RC pulley to replace condenser though.
By now, you'll have a shit load of parts, and it's taken 2 hours and no money, well unless you took the ac out and had to buy the RC pulley.
Probably saved 50kg so far.
Take car for drive, it sounds and feels awesome. Let's do more of this. Have to spend money now.
Wilwood or AP racing brakes. They're lighter, but also unsprung, the best kind of weight saving. They might expensive, but just do it. Anyone saying pads and fluid on stock brakes will be good enough must drive like a pansy. It isn't.
Let's make car rev better, with lighter parts.
Toda pulley kit. Only kit I know that's under drive. Most kits are just lighter, this kit also drains motor less.
Toda flywheel and pulley clutch. Don't get a cheap/alloy flywheel.
Carbon driveshaft.
Tomei titanium cat back.
Take car for drive now.
Oh, get some wheels and tyres, but the stuff above will have bigger impact. Do stuff above first.
Wheels are hard, all stuff above is hidden. Wheels still need to look good. Everyone obsesses about wheel weight, but then put dumb 'meaty' tyres on, so end up with heavier wheel/tyre combo than stock. 205/40 semi slick on stock wheel will weigh less than forged wheel with big dumb tyre, and will have MORE grip. Put semi on forged wheel for win if you can.
205/40/17 semi (or any tyre that size also lowers overall gearing, which will make car feel even lighter.
More savings? Headers, seats. Bought all I can think of atm. That's the main ones anyway. At this point you'll just be chasing one or two pounds, and will be costly. Just wait till you need to replace something, then find the lightest functional option you can. Dont just but mods because mods are cool, you'll just undo all the coolness that you have done if you've done all the above.
Go race poorly setup poorly modded turbo cars around hills. Welcome to the new age, takumi.
