About This Lexus GS300 Base 1999 Build
We love featuring real builds from real owners. This Lexus GS300 Base 1999 sits on a set of 18×9.5 / 18×12-inch SSR Gartmaier wheels, and the result speaks for itself.
The owner chose SSR for a reason. This brand delivers serious quality and a design language that turns heads at every car meet. We see hundreds of Lexus GS300 Base builds come through WheelFront every month, but this one stands out. The combination of the exterior with the SSR Gartmaier creates a look that balances aggression with elegance.
Fitment Breakdown: SSR Gartmaier on the Lexus GS300 Base 1999
I walked around this GS300 at the show and the fitment absolutely blew my mind. You are looking at a set of SSR Gartmaiers sized at 18x9.5 up front and a massive 18x12 in the rear. That rear width is serious business for this chassis.
The offsets are pure madness, sitting at -1 in the front and 0 in the back. These wheels push way past the factory lines to give the car a wide, aggressive stance. It fills those arches perfectly when the air suspension hits the floor.
You have to worry about the factory front calipers with these faces. The Gartmaiers have a flat profile that can catch on the brakes if you do not measure twice. I suggest a small spacer if you find the clearance too tight during install.
The rear fitment requires a heavy pull or a widebody kit on the 1999 GS300. Without serious fender work, those 18x12s will eat your tires for breakfast. You need to pull those metal fenders out to match the aggressive lip depth.
The hub bore on these SSR wheels fits the Lexus hub perfectly with the right rings. I love how the deep-dish barrels catch the light when the car is aired out. It makes the car look much wider than the factory sheet metal suggests.
Rubbing is a constant battle with this setup. Even with the air suspension dialed in, your inner liners will get chewed up if you drive too low. Keep an eye on those clearance points when you test your turning radius.
This setup is not for the faint of heart or the daily commuter. It is a show-ready configuration built for maximum impact. You must commit to the lifestyle if you want to run Gartmaiers this wide.
What We Recommend for Lexus GS300 Base 1999 Owners
If you want to replicate this look, stick to the 18-inch diameter. It keeps the proportions classic for the 1999 chassis while leaving room for a healthy tire sidewall. Anything larger starts to look like a wagon wheel on this body style.
Aim for an offset between +15 and +25 if you want to avoid massive fender cutting. That range keeps the wheels flush without requiring a full body shop rebuild. You can always throw on a 10mm spacer later if you want more poke.
Avoid square setups on the GS300. This car looks best with a staggered width, so run a wider wheel in the rear to fill those hips. A 9-inch front and 10.5-inch rear is my favorite street-friendly combination.
Tire stretch is a mandatory evil here. You need a slightly narrower tire to tuck the wheel inside the fender when you hit the air switches. Pick a performance tire with a rounded sidewall to make the stretch look clean rather than dangerous.
Do not forget to roll your fenders before you drop the car. If you skip this, your first bump will destroy your paint and your tires. Take your time with a fender roller and a heat gun to prevent cracking the clear coat.
Style and Build Analysis
The pink finish on these SSR Gartmaiers is a bold, unapologetic choice. It pops against the dark body paint of the GS300 in a way I rarely see. Most builders go for chrome or silver, but this pink brings a custom vibe that makes the car unforgettable.
The Gartmaier is a legendary wheel design with those signature circular cutouts. They look industrial and retro all at the same time. On this specific Lexus, the wheels ground the design and give it a heavy, planted aesthetic.
When the air suspension drops the frame to the pavement, the car looks like a piece of art. The wheels do not just sit on the car; they dominate the entire visual profile. You cannot look away from the way the barrels disappear into the wheel wells.
This build stands out because it balances luxury with pure aggression. The GS300 is a sophisticated platform, and these wheels add a layer of grit. It feels like a drift car that accidentally ended up at a luxury car gala.
I have seen hundreds of GS builds, but this one sticks in my head. The proportions are dead on, and the color palette is brave. It shows exactly what happens when a builder stops playing it safe and goes for the throat.
Why We Love This Build
This Lexus breathes soul into the 90s luxury segment. The hot pink wheels catch the sunlight and create a contrast that makes the whole machine glow. When the air suspension vents, the car settles over those Gartmaiers like a predator preparing to pounce.
We love this build because it celebrates the spirit of modification without compromise. Every inch of this car feels intentional and loud. It forces every person at the show to stop, stare, and appreciate the craftsmanship behind the stance.
Seeing this car in person confirmed that bold choices pay off. It is a masterclass in aggressive fitment and color coordination. Build your dream, and do not let anyone tell you that pink wheels do not belong on a VIP Lexus.

Before You Buy: Fitment Checklist
We talk to Lexus GS300 Base owners every day. These are the questions we hear most before they pull the trigger on new wheels.
Will 18×9.5 / 18×12-inch wheels fit my Lexus GS300 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 Lexus GS300 Base owners run 18×9.5 / 18×12-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
