About This Mazda RX-8 Grand Touring 2009 Build
We love featuring real builds from real owners. This Mazda RX-8 Grand Touring 2009 sits on a set of 18×9.5 / 18×9.5-inch Motegi MR145 wheels, and the result speaks for itself.
The owner chose Motegi 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 Grand Touring builds come through WheelFront every month, but this one stands out. The combination of the exterior with the Motegi MR145 creates a look that balances aggression with elegance.
Fitment Breakdown: Motegi MR145 on the Mazda RX-8 Grand Touring 2009
I walked around this RX-8 for twenty minutes at the last meet. The Motegi MR145 wheels in an 18x9.5 setup completely transform the stance of this chassis. That plus-35 offset pushes the face out perfectly to the edge of the fenders.
We see a lot of guys struggle with the RX-8 wheel wells. This specific setup nails the fitment without needing aggressive body work. You get that flush look that makes the car look planted and ready for the track.
The hub bore fits the Mazda hub like a glove. We never see vibrations or sloppy centering with these Motegis. The spoke design gives you just enough room to clear those stock Grand Touring calipers without any spacers.
That 9.5-inch width is the sweet spot for the RX-8 platform. It gives you a nice, meaty tire patch for cornering grip. The barrel depth looks deep enough to provide a high-end look without losing structural rigidity.
Those coilovers are doing the heavy lifting here. They drop the car low enough to kill the wheel gap while keeping the alignment specs in check. You still need to watch the inner fender liner if you take a corner too hard.
I looked closely at the clearance on the front struts. You have just enough room to avoid rubbing on the spring perch. It is a tight fit, but it clears exactly how we like it.
Watch your tire choice carefully on this setup. A 255-width tire is probably your limit before you start hitting the fender lips on big bumps. Keep your rubber square to maintain that neutral balance the RX-8 is famous for.
What We Recommend for Mazda RX-8 Grand Touring 2009 Owners
If you want to replicate this look, stick to an 18-inch wheel. Anything larger ruins the ride quality and makes the car look like a cartoon. The 18-inch diameter keeps the proportions tight and sporty.
We always suggest a square setup for the RX-8. Staggered wheels might look cool, but they destroy the handling characteristics of the rotary platform. Keep the width the same front and back for predictable grip.
Don’t go too crazy with your offset. Anything lower than a plus-30 will likely force you to roll your fenders or add significant camber. We prefer keeping the fenders stock if you can help it.
Avoid cheap spacers at all costs. If you buy the right offset, you will never need them anyway. Spacers just add unnecessary stress to your wheel bearings and suspension components.
Pick a high-performance summer tire to match these Motegis. A cheap all-season tire will just waste the potential of this wider track width. You want something with a stiff sidewall to handle the lateral G-forces.
Always double-check your alignment after you install your coilovers. A good street-track alignment makes the car feel ten times more responsive than stock. Don't leave your alignment settings to chance.
Style and Build Analysis
The bronze finish on these wheels is a total knockout against the RX-8 bodywork. It pops just enough to get noticed without looking tacky or loud. Bronze is the hidden gem of wheel colors for this specific car.
The design of the MR145 is clean and functional. Those thin spokes let you see the brakes clearly, which adds to the mechanical aesthetic. It looks like a car that belongs on a twisty mountain road.
I love how the wheels fill the arches. There is no awkward tucked look, but there is also no ridiculous poke that looks like a circus act. It is a mature, refined look for a driver who knows their stuff.
Compared to other builds we feature, this one feels very intentional. Many owners just slap on the widest wheel they can find and hope for the best. This builder measured twice and cut once, and it really shows.
The car has a purposeful, aggressive presence now. It sits lower and wider, which highlights those signature fender flares. This is exactly how Mazda should have sent the car out of the factory.
Why We Love This Build
This RX-8 stops us in our tracks because it is perfectly balanced. The bronze Motegis catch the afternoon light, glowing against the metallic paint. You can tell this car gets driven hard, not just parked at shows.
We love the way the wider footprint changes the car's silhouette. It looks meaner and more capable every time we look at it. The stance is absolute perfection, sitting low and flush without any unnecessary drama.
This is the build that makes me want to go buy an RX-8 tomorrow. It represents the spirit of the aftermarket scene done right. Put these wheels on your car and never look back.

Before You Buy: Fitment Checklist
We talk to Mazda RX-8 Grand Touring 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 Mazda RX-8 Grand Touring? 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 Grand Touring 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.
