I also lose about 2lbs when I go to the bathroom before I go to track lol.
Dude. Just found the channel and love it! Ive been preaching that hp is not near as important as weight savings on my channel for a while and finally others are starting to see that.
My content is about my swapped GC that weighs 2750lbs. Its a track beast...
@@traviscea it's hard to find ppl with this mindset, all the Subaru owners just want to make power, but a lot don't realize you can't put that power down anywhere on a track. You end up with a huge power rush, then you have to over brake, losing a lot of time in corners, rather than smooth momentum driving with stock power levels, and better cornering speeds with less weight and focus on suspension and handling upgrades.
@@traviscea also I just subscribed and will check out your vids!
I run the 18" BBS wheels from the S203/S204/2013 tS Type RA/2018 Type RA-R, and they are roughly 17lbs each corner. So much better than the stock 19" wheels on my 2019 STI.
Yeah definitely, I'm gonna be running BBS rev7s which are 19 lbs/corner 18x9.5 +45
Stock STI wheels are so damn heavy its insane. I switched to a cheapo set of Enkei TSVs and was shocked how different the car felt
@@Mvonada yeah the steering feel itself is so much better when it's not lugging around those 28 lbs boat anchors lol
Great video! Weight reduction is my biggest performance goal with my STi so I really appreciate you sharing your progress in that area!
Imo it makes all the difference on these cars, especially if you can remove weight on the front end to improve better turn in and reduce understeer
@@TheLastS209 That’s good to know! Installing an Antigravity battery seems like a really overlooked mod. My favorite part of the Sti is the feel(especially steering). So far all of my modifications have been drivetrain bushings, steering rack bushings, short shift, underbody bracing(love), sway bar and end links, strut tower brace, motor mounts, trans mount, pitch stop mount, and Ti exhaust …I’ve done nothing to gain any power yet(except exhaust), and honestly I don’t really feel the need to. The car is way more fun to drive with the chassis stiffening mods.
@@micahgunnell this is the correct way to mod the car imo!
I have regular 2015 STi. After switching to WedsSport 18x9.0 +50mm 16.9LB per rims feels great.
I used to have 18x9.5 +45 tc105x, those were amazing
Beautiful car and excellent weight savings! Have you been to the track at Club Motorsports in Tamworth, NH? If you haven't, I highly recommend it! It's similar to Palmer, but longer, wider, and more elevation.
Side mirrors. Titanium exhaust one exit noble makes one it’s full titanium great price great weight savings. The Stis don’t make enough horsepower to care for a dual. Back on the side mirrors get carbon you’d be surprised how much just those factory ones weigh. I’m currently moving but when I’m moved I’m making a full carbon floor mat that will mount to the seat bolts that way I can take out the carpet in the whole car. That was a lot of weight on my evo 9 rs that I had as a daily. Crash beam front and rear remove and replace with aluminum will save weight. Move wiper fluid to rear and battery to rear gets you closer to 50/50 weight distribution when you do ti exhaust.. door cards carbon saves weight. Speakers remove and put into seats smaller speakers. Saves weight and on those long trips you can still rock hard.. can’t think of other things right now. Not bad video. Seems like your starting keep it up.
Yeah this is a great list. After I reach my goal of 1:49 at my local track, then I plan on another ~100 lb of weight reduction, gonna get it close to 3200 lbs. That's the most I'll do, I don't want to get to the point of no return with this car, if you know what I mean.
sweet s209 i hope to see you on the road
Thanks you too! Be sure to like and subscribe. Thanks!
Carbon fiber baby seat perhaps??
Absolutely love weight reduction. My Impreza looks like a Kanjozoku Civic(which I am a huge fan of). Daily driven, not for everyone, but it is so fun! Air bags and side impact beams and such still intact for safety though. Love the gains from the driveshaft you did, but having it not collapsible would mess with my mind.
Have you thought about the mirrors, like an APR GT3 mirror? Might be a bit much for daily use, but I'd imagine there is a substantial difference.
Also, when you do the exhaust manifold, consider the up pipe as well, as most solid aftermarket ones are about 2lbs lighter than an OEM catless up pipe. I'd recommend HKS as well. Our HKS up pipe mated to an OEM exhaust manifold fit as well as the OEM up pipe. On our other Impreza, I just replaced a very old OEM up pipe that finally cracked, with a Cobb up pipe(quickest I could get), mated to a Killer B exhaust manifold, and the fitment between the two was definitely not awesome. Just a thought. HKS up pipe pn: 34998-BF001
Lastly, again, might be a bit much for a daily S209, but the plastic4performance lexan windows would be a good bit of weight savings, especially nice since they are on the upper half of the car.
Great video!
do you actually have the last 209 of the s209?!?! that's pretty cool if you do bro
Wow that's what I weigh! Just make it autonomous and I matched you ;)
Nice video
What CF driveshaft did u choose??
Thinking about getting one
Driveshaft shop
@@TheLastS209 any downsides from the cf driveshaft?
any noise on the higher speeds?
@@Afos3 No downsides as long as it's installed correctly and not defective. There are some people who report vibrations at higher speeds, could be due to incorrect installation or a defective driveshaft. Once installed, you get a lot less NVH in the cabin, and the car just wants to turn in more easily. Responds to inputs much faster than with the OEM driveshaft. Be sure to like and subscribe. Thanks!
@@Afos3 The two-piece is designed to drop the transmission below you in a head-on crash, instead of having it come into the cabin. Not that much of an issue on a track though.
@@TheLastS209 did you install it yourself or used a local shop?
Hi there,
😊
Can you share what bumper beam you used?
Thank you
3,000 lbs would be insane! Are there any cons to the CF driveshaft for a daily?
Not that I know of. Some ppl have reported vibrations at higher speeds, but I haven't experienced that, could be a defect or incorrect installation. Overall it's a win win when it's working properly imo
If you hit something head-on, the transmission will no longer drop down and below you like it's designed to do with the two-piece, it will crush your legs.
@@leviwedel Nah, it still will. The single carbon shaft isnt strong enough in that direction of impact and it will shear easier than the stock shaft would. Ive seen it a few times myself.
free weight reduction is awesome. Paid weight reduction not as much. I understand the goal is for the best possible track day, but some of the paid reductions seem over the top. When going to the track, you can also remove the rear door cards and rear seat, unless you have rear seat passengers going along.; but still an option.
Is the glove box and center cubby empty? Do you take out the unused head rests too?
Yeah that's the easy stuff. Door cards weigh almost nothing, and you are making the weight distribution even worse if you remove weight from the rear. That's why the paid weight reduction from things in the front is more beneficial than you might think.
If you ever think of dropping another pound, I have an uninstalled HKS Cold Air Intake with the carbon fiber box that I'm willing to let go for the oem S209 intake 👀
No I'm probably never touching the engine in terms of mods
@@TheLastS209 Understandable. I'm technically replicating Jeff's build almost to the T with my 2020 STI and I'm looking to get my hands on S209 goodies but it's practically impossible without owning one to do so. I have the third ASE VF58 in the states (this one is in Massachusetts, the other one is in the Pacific Northwest, and Jeff's in New Jersey I believe) , and going as OEM+ as I can.
Im 198 lbs, I probably need to lose weight to get some real weight reduction lol
I've stayed the same weight for years now so I don't even factor that in haha
@@TheLastS209 same here, I've been the same weight since high school and I graduated 17 years ago lol. Filipino/Mexican dont gain weight if you're active every day, which is what I am. I still look 20 even though Im 35. Everyone I went to HS with looks like they're 50 now lolololzzz.
I will get fuel starvation ever under 70% of tank in Thompson after the 3 turns to get in to final straight.
That's pretty bad, I'd definitely get that resolved first
simply way to add a starvation door, you could find in Verus Engineering@@TheLastS209
Take a poop u loose 2lb, then take the rear end out that’s 107lb the mufflers is 20 ontop of that so go titanium headers all the way to the back carbon driveshaft is like 30-40ish pounds or something that, I did all this to street race and it actually launched harder and better
How does that battery work with cold temps and longer periods without starting?
No issues, it works like a regular battery
You forgot to put "Binaural" in your description. Also, if you don't have stickers on your vehicle, you are basically a Prius.

Where did you source your endless 2pc rotors from?
I have a vid on it here: ruclips.net/video/0PDoU6V5qeE/видео.htmlsi=f15HP8W0s2oTqscz
Look in comments section for part numbers, japanparts sells them. Thanks for watching! Please subscribe if you haven't already. Thank you
Are you going to sell your oem wheels? If so I'd love to buy them
Nope keeping them forever
Does the drive shaft make noise ?
No quiet like oem
STi lightweight Flywheel!
Yeah these s209s already have that 😅
They unfortunately do not. It was in the original press release with the forged pistons. It was then removed from the final release. I dug through all the parts lists and it has the same part number as other STi@TheLastS209
@@jeffarcher8791 oh interesting! Good to know
Its definitely on my to do list asap! As well as a 4.44 conversion with Spec B 5th and 6th gears. @TheLastS209
@@jeffarcher8791 what's the part number for it?
dang, removing safety features while having a baby in the back........
Is a one piece cf driveshaft really that bad from a safety standpoint? Other than the driveshaft, I don't see any other modification I've done as harmful.
