About This Subaru WRX STI Base 2017 Build
We love featuring real builds from real owners. This Subaru WRX STI Base 2017 sits on a set of 18×9.5 / 18×9.5-inch WedsSport Tc105x wheels, and the result speaks for itself.
The owner chose WedsSport for a reason. This brand delivers serious quality and a design language that turns heads at every car meet. We see hundreds of Subaru WRX STI Base builds come through WheelFront every month, but this one stands out. The combination of the exterior with the WedsSport Tc105x creates a look that balances aggression with elegance.
Fitment Breakdown: WedsSport Tc105x on the Subaru WRX STI Base 2017
I stood right next to this STI when the owner pulled into the lot, and the stance hit me instantly. We are looking at a perfect 18x9.5 setup wrapped in the classic WedsSport Tc105x design. These wheels sit flush with the fenders without needing any wild camber adjustments.
The +35 offset is the golden ticket for the VA chassis. It pushes the wheel out just enough to kill that sunken look Subaru gives us from the factory. You get a broad, aggressive track width that actually helps the car rotate in tight corners.
Caliper clearance is the biggest headache for STI owners because of those massive Brembos. Luckily, the Tc105x barrel design clears those front stoppers with plenty of room to spare. You will never worry about the spokes hitting the calipers here.
The hub bore fits the Subaru 56.1mm center perfectly. We always suggest running a high-quality hub-centric ring to keep everything vibration-free at highway speeds. It is a small detail that saves you a massive headache during long drives.
Because the car sits on coilovers, the wheel gap is non-existent. The tires tuck just inside the fender liners when the suspension compresses hard. We checked the clearances closely, and there is zero rubbing on the inner plastic guards.
Those spokes feature a CNC-machined edge that makes the wheel look even larger than it is. The thin, rigid design shaves off a ton of unsprung weight compared to heavy cast wheels. You can actually feel the lighter steering response every time you turn the wheel.
Watch out for the rear fenders if you decide to go with a wider tire, though. We recommend rolling the inner lips slightly if you plan to slam the car even lower. This setup strikes the right balance between track performance and street-ready style.
What We Recommend for Subaru WRX STI Base 2017 Owners
If you want to replicate this look, stick to the 18x9.5 square setup. Staggered wheels on an AWD platform like the STI are a recipe for drivetrain disaster. We always advocate for keeping the same tire diameter at all four corners to save your center diff.
For the tires, a 255/35/18 or a 265/35/18 provides the best contact patch. The 255 gives you that slight stretch that makes the sidewall look crisp and race-ready. A 265 will offer more grip if you spend your weekends attacking mountain passes.
Avoid the temptation to use cheap spacers to push the wheels further out. These Tc105x wheels already sit in the sweet spot for the VA chassis. Adding spacers just puts unnecessary stress on your wheel bearings and ruins the scrub radius.
Always pair a nice wheel upgrade with a decent set of coilovers. Stock suspension makes even the best wheels look awkward and out of place. You need that drop to make the geometry work and to get the tire sitting exactly where it should.
Do not skip on a proper alignment after you install the wheels. Dialing in a bit of negative camber keeps the tires from chewing up your fender liners. A good shop will get this dialed in so the car handles like it is on rails.
Style and Build Analysis
The Gunmetal finish on these WedsSports is pure understated aggression. It does not scream for attention like neon wheels, but it commands respect from anyone who knows their parts. The matte texture hides brake dust better than any gloss finish we have tested.
Against the factory paint, this wheel color creates a sophisticated, mechanical look. It reminds me of a proper rally car that just rolled off a special stage. The proportions look intentional, like the car was engineered specifically to run this exact wheel.
We see a lot of flashy builds, but this one relies on clean lines and smart engineering. The Tc105x is a motorsport icon for a reason, and it shines on this chassis. It elevates the STI from a street car to a machine that looks ready for the track.
The thin spokes allow you to see the rotors clearly. It creates a sense of depth that makes the whole corner assembly look expensive and high-tech. You get an industrial aesthetic that feels right at home on a Japanese tuner car.
This build proves that you do not need a widebody kit to make an STI look menacing. It is all about selecting the right offset and getting that drop just right. The car looks planted, wide, and absolutely ready to hunt apexes.
Why We Love This Build
We love this build because it feels authentic and dialed. That Gunmetal finish catches the afternoon sun and makes the wheels pop against the aggressive lines of the STI body. The way the tires fill the arches shows the owner did their homework on the fitment math. It transforms the car from a commuter into a focused piece of machinery that commands every eye in the parking lot.
You can see the heritage of the WedsSport name in every angle of this setup. It is a build that respects the Subaru rally legacy while keeping things modern and clean. This STI looks fast even when it is standing perfectly still at the curb.
Stop overthinking your wheel choice and just commit to a setup like this one. It is the ultimate upgrade for the VA platform. Do it once, do it right, and enjoy the ride.

Before You Buy: Fitment Checklist
We talk to Subaru WRX STI Base owners every day. These are the questions we hear most before they pull the trigger on new wheels.
Will 18×9.5 / 18×9.5-inch wheels fit my Subaru WRX STI Base? Yes, but fitment depends on width, offset, and tire size working together. A wrong offset means rubbing. A wrong tire size means poor handling. Always verify all three.
Do I need to modify my fenders? That depends on your offset and suspension. A conservative offset with stock ride height usually fits without modification. Go aggressive and you may need to roll or pull your fenders.
Can I daily-drive this setup? Absolutely. Thousands of Subaru WRX STI Base owners run 18×9.5 / 18×9.5-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
