About This Subaru Impreza WRX STI 2011 Build
We love featuring real builds from real owners. This Subaru Impreza WRX STI 2011 sits on a set of 18×9 / 18×9-inch Enkei RS05-RR wheels, and the result speaks for itself.
The owner chose Enkei for a reason. This brand delivers serious quality and a design language that turns heads at every car meet. We see hundreds of Subaru Impreza WRX STI builds come through WheelFront every month, but this one stands out. The combination of the exterior with the Enkei RS05-RR creates a look that balances aggression with elegance.
Fitment Breakdown: Enkei RS05-RR on the Subaru Impreza WRX STI 2011
I saw this 2011 STI in person last week and the fitment stopped me dead in my tracks. Running 18x9 Enkei RS05-RR wheels with a +35 offset is exactly how this chassis should look. It fills those wide fenders perfectly without looking like a circus wagon.
The +35 offset pushes the wheel right to the edge of the fender line. You get that aggressive stance while keeping the scrub radius mostly factory. It is a calculated move that balances form and track capability.
Caliper clearance is the biggest headache on the STI, but these wheels clear the Brembos easily. The concave face of the RS05-RR design provides all the room you need for those big calipers. You will not need any spacers to keep the wheels from hitting the hardware.
The 18x9 width is the golden ticket for the GR chassis. It allows for a nice, meaty tire profile that actually puts power to the pavement. You get plenty of grip without sacrificing steering feel or turning your wheel wells into shredders.
These coils are set to a stiff rebound, which helps keep the tires from kissing the liners. If you go too low, you might rub the fender tabs in the rear. I suggest trimming the rear tabs if you want to dial in that last bit of drop.
The hub bore fits the Subaru platform like a glove. Enkei engineered these with the right center bore so you avoid those annoying vibration issues. It feels planted, solid, and ready for a canyon run or a track day.
The barrel design is surprisingly deep for a wheel in this class. It gives the car a much more substantial look than the stock rollers. These wheels look like they belong on a rally stage, not just a mall parking lot.
What We Recommend for Subaru Impreza WRX STI 2011 Owners
If you want to replicate this look, stick to the 18x9.5 range if you are willing to roll your fenders. For a direct bolt-on experience, the 18x9 setup is unbeatable. Do not get greedy with massive widths unless you want a headache with alignment specs.
The offset sweet spot for this car is between +35 and +40. Anything lower than +35 and you are going to be fighting fender rub every time you hit a bump. Stay in the +35 zone and you keep the car usable for daily driving.
Skip the staggered setups on an AWD Subaru. You want the same wheel and tire size on all four corners to save your center differential. Keep it square and keep your drivetrain happy for the long haul.
Don't bother with cheap spacers to get that "poke" look. Proper offset, like the +35 on these Enkeis, gives you the perfect look without needing extra hardware. Spacers only add points of failure that you do not need.
For tires, look for a 245 or 255 width to keep things tidy. A 245/40 will give you a slight stretch if that is your vibe. If you want function, the 255/35 fits the 18x9 wheel face perfectly and protects the rim.
Style and Build Analysis
The Gray finish on these RS05-RR wheels is a masterclass in subtlety. It pulls out the metallic flakes in the car's paint without screaming for attention. It looks moody, industrial, and distinctly Japanese.
The multi-spoke design of the RS05-RR is pure motorsport history. Those thin, elegant spokes draw the eye straight to the brake discs. It makes the car look lighter and much faster just standing still.
Proportions are everything on the GR STI platform. The 18-inch diameter keeps the sidewall thick enough to handle potholes while filling the wheel arch nicely. It looks balanced and intentional, not like a toy.
Compared to the heavy, cluttered stock wheels, these are a massive visual upgrade. The Enkeis are clean and lean, which makes the whole car look more athletic. It highlights the wide-body arches that make this generation of STI so iconic.
Road presence is where this build truly shines. It commands respect without being flashy or gaudy. You know the owner understands the balance between style and raw performance immediately.
Why We Love This Build
This car is the perfect example of how a few smart choices can transform an entire build. The Gray Enkei wheels against the aggressive STI body lines look like a factory dream. It sits low, looks mean, and carries that rally heritage with absolute confidence.
We love how the RS05-RR design captures the light as the car rolls down the street. It makes the whole package feel cohesive and tight. This build is not just a collection of parts; it is a vision realized.
It makes me want to run out and grab a set for my own project immediately. This is exactly what a modified STI should look like. Put the right shoes on your car and never look back.

Before You Buy: Fitment Checklist
We talk to Subaru Impreza WRX STI owners every day. These are the questions we hear most before they pull the trigger on new wheels.
Will 18×9 / 18×9-inch wheels fit my Subaru Impreza WRX STI? 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 Impreza WRX STI owners run 18×9 / 18×9-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
