About This Mazda RX-8 GT 2004 Build
We love featuring real builds from real owners. This Mazda RX-8 GT 2004 sits on a set of 18×8.5 / 18×8.5-inch STR 905 wheels, and the result speaks for itself.
The owner chose STR for a reason. This brand delivers serious quality and a design language that turns heads at every car meet. We see hundreds of Mazda RX-8 GT builds come through WheelFront every month, but this one stands out. The combination of the exterior with the STR 905 creates a look that balances aggression with elegance.
Fitment Breakdown: STR 905 on the Mazda RX-8 GT 2004
I walked around this RX-8 for twenty minutes at the last meet. The STR 905s in 18x8.5 all around give this chassis a serious, aggressive stance. That +30 offset pushes the wheels right out to the edge of the fenders.
We see a lot of RX-8s, but this setup avoids the sunken look. The +30 offset creates a flush profile without needing massive spacers. It really highlights the RX-8's flared arches perfectly.
Caliper clearance on these STR wheels surprised me. The spokes arc outward enough to clear the stock GT brakes without drama. You do not need to worry about rubbing the barrel on the caliper housing.
The hub bore fits the Mazda specs without any sketchy adapters. I checked the seating, and the wheels mount clean to the hub face. Solid contact means no annoying vibrations at highway speeds.
The 8.5-inch width is the sweet spot for a square setup on this car. You get plenty of tire contact patch for the rotary power. It balances the grip front-to-rear for predictable handling.
Because the car sits on coilovers, the wheel gap is non-existent. You might see some light rubbing on the inner fender liner if you hit a big dip. A quick roll of the fender lips solves that problem easily.
The barrel lip depth on the 905 provides a nice visual anchor. It breaks up the black paint and adds some depth to the profile. This design keeps the car looking purposeful and track-ready.
What We Recommend for Mazda RX-8 GT 2004 Owners
If you want to replicate this look, stick to the 18x8.5 or 18x9 sizing. Going wider than 9.5 inches usually causes clearance issues with the front control arms. We have seen too many owners regret buying wheels that poke too much.
For offsets, stay between +30 and +35 for that flush look. Anything higher than +40 starts to tuck the wheel too far into the wheel well. You want the wheels to fill the space, not get swallowed by it.
I always suggest running a square setup on the RX-8 platform. It lets you rotate your tires and keeps the car neutral in the corners. Staggered setups often induce understeer, which ruins the fun of this chassis.
Do not cheap out on your tire choice just to afford the wheels. A high-performance summer tire makes a world of difference with these STR 905s. You need the grip to match that aggressive offset.
If you plan to slam the car, prepare to roll your fenders. Even a mild drop can cause the tire shoulder to kiss the fender tab on hard bumps. Take your time with the roller and heat gun.
Avoid massive spacers if you can help it. They put unnecessary stress on your wheel bearings and studs. Get the right offset from the start and skip the headache.
Style and Build Analysis
The black finish on these STR 905s looks mean against the body. It gives the car a murdered-out vibe that suits the RX-8 lines perfectly. The dark spokes seem to disappear into the shadows, making the car look wider.
I love how the wheel design mimics classic motorsports styling. The multi-spoke pattern adds a layer of complexity to the clean RX-8 bodywork. It looks fast even when it sits perfectly still in the parking lot.
The proportions feel just right for this generation of Mazda. Many people overdo the wheels on this car, but this build keeps it tight. The balance between the wheel size and the lowered ride height is spot on.
Compared to other builds, this one shows restraint. It avoids the neon colors and massive wings that usually crowd the RX-8 scene. It lets the wheels speak for themselves through simple, clean design.
Every time I see this car, I notice something new. The way the light hits the concave face of the 905 really pops in the sun. It creates a dynamic look that changes as you walk around the car.
Why We Love This Build
This RX-8 stops me in my tracks every single time. The black STR 905s look like they belong on a track car, yet they function perfectly on the street. When the sun hits the paint, the contrast between the dark wheels and the body makes the car look like a predator ready to pounce. It is a masterclass in how a simple wheel swap transforms the entire presence of a car.
I love seeing owners focus on fitment over flash. This build proves that you do not need thousands of dollars to create a head-turning machine. It is clean, it is aggressive, and it is built to be driven hard. Grab a set and go drive.

Before You Buy: Fitment Checklist
We talk to Mazda RX-8 GT owners every day. These are the questions we hear most before they pull the trigger on new wheels.
Will 18×8.5 / 18×8.5-inch wheels fit my Mazda RX-8 GT? 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 Mazda RX-8 GT owners run 18×8.5 / 18×8.5-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
