About This Subaru Forester S 1999 Build
We love featuring real builds from real owners. This Subaru Forester S 1999 sits on a set of 18×10.5 / 18×10.5-inch Kansei Tandem wheels, and the result speaks for itself.
The owner chose Kansei for a reason. This brand delivers serious quality and a design language that turns heads at every car meet. We see hundreds of Subaru Forester S builds come through WheelFront every month, but this one stands out. The combination of the exterior with the Kansei Tandem creates a look that balances aggression with elegance.
Fitment Breakdown: Kansei Tandem on the Subaru Forester S 1999
I walked around this SF Forester for ten minutes straight at the meet. Slapping 18x10.5 wheels on a 1999 chassis is absolute madness in the best way possible. That +12 offset pushes the Kansei Tandem right out to the edge of the world. It turns a boxy grocery getter into a wide-body menace.
The Kansei Tandem carries a deep, aggressive barrel that grabs your eye immediately. You can see the sheer depth of the lip from three cars away. It completely transforms the visual weight of the Subaru platform. The 10.5-inch width makes the car look like it sits ready for a track day.
We checked the caliper clearance and it barely misses the hub assembly. You definitely need those coilovers cranked down to make this specific setup work. The coilovers eliminate the factory wheel gap that usually kills the look of these old wagons. Without the stiff dampening, these wheels would eat the inner fender liners for breakfast.
The hub bore fits tight, but watch your clearances near the inner struts. You might experience some rubbing on full lock if your alignment isn't dialed in perfectly. I suggest checking the inner barrel clearance every time you hit a pothole. It is a tight dance between the metal and the chassis.
The spokes on the Tandem provide a clean look that hides the heavy suspension geometry of the 99 chassis. They keep the unsprung weight manageable despite the massive width. The design flows perfectly with the sharp, nineties-era body lines of the Forester S. It feels like a throwback build with modern muscle.
I noticed the fender gap is non-existent here, which is exactly how you want it. You will need a serious roll on those rear arches to keep from shredding your tires. These wheels demand respect and a heavy-duty fender roller. If you try to run this setup without modifying the body, you will destroy your paint.
What We Recommend for Subaru Forester S 1999 Owners
Most owners should start with a 17x9 setup if they want to drive hard every day. You get way more tire choice and less headache with your steering rack. If you choose the 18-inch route, commit to the fender work early. Do not cut corners on the metal prep or you will regret it.
Staggered setups usually hurt the AWD system on these old Subarus. Stick to a square setup with matching offsets on all four corners. We always recommend keeping the rolling diameter consistent to save your center diff. Your drivetrain will thank you when you avoid unnecessary binding.
Tire stretch is a massive factor when you push an 18x10.5 wheel onto this car. We suggest a slight stretch to tuck the tire shoulder under the fender lip. It keeps the rubber away from the sharp metal edges during hard cornering. You want function and form to live in harmony here.
Do not forget the importance of high-quality lug nuts and hub-centric rings. These wheels are light, but they put a lot of leverage on your wheel studs. We have seen too many builds fail because someone skipped the rings. Buy the good hardware the first time around.
Avoid massive spacers if you can help it. You already have a +12 offset which provides plenty of poke for most tastes. Adding spacers just puts unnecessary stress on your wheel bearings and hubs. Keep the fitment clean and keep your suspension geometry as close to stock as possible.
Style and Build Analysis
The Gunmetal finish on these Kansei Tandems looks incredible against the Forester’s paint. It is a muted, industrial color that screams performance without trying too hard. It avoids the flash of polished lips while maintaining a premium, high-end feel. The contrast makes the car look darker and more menacing at twilight.
The spoke design pulls the eye directly to the center of the wheel. It creates an illusion of a larger brake setup hidden behind the spokes. We love how the flat face of the Tandem matches the squared-off silhouette of the 99 model. It feels like a design language that was meant to be paired together from the factory.
Proportions define this build, and they are spot on. Most people go too small on the SF chassis and lose the aggressive stance. By jumping up to an 18-inch wheel, the owner reclaimed the road presence of the vehicle. It looks like it belongs on a rally stage rather than a suburban driveway.
Compared to other builds we have featured, this one stands out for its simplicity. There are no garish decals or distracting colors, just perfect fitment and clean wheels. It proves that you do not need a wild kit to make a Forester look iconic. You just need the right offset and a good set of coilovers.
The stance sits aggressive but remains purposeful. You can tell this car gets driven hard and not just parked at shows. The way the wheels fill the wheel arches gives the car a hunkered-down look. It is the perfect balance of aesthetic perfection and mechanical capability.
Why We Love This Build
When the sun hits that Gunmetal finish, the Kansei Tandems practically glow. They turn this humble 1999 Forester into a masterpiece of modern fitment. Seeing the wheels tuck perfectly under those rolled fenders makes my heart race. It is the kind of aggressive aesthetic that forces every car enthusiast to stop and stare.
We love this build because it ignores the boring path and chooses the bold one. It pushes the boundaries of what fits on an older Subaru without ruining the soul of the car. It is raw, it is loud, and it is absolutely perfect. This is the gold standard for how to modify an SF Forester.
Stop dreaming about your build and go make it happen.

Before You Buy: Fitment Checklist
We talk to Subaru Forester S owners every day. These are the questions we hear most before they pull the trigger on new wheels.
Will 18×10.5 / 18×10.5-inch wheels fit my Subaru Forester S? 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 Forester S owners run 18×10.5 / 18×10.5-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
