About This Mazda RX-7 Turbo 1987 Build
We love featuring real builds from real owners. This Mazda RX-7 Turbo 1987 sits on a set of 18×9 / 18×9-inch Cosmis Racing MR7 wheels, and the result speaks for itself.
The owner chose Cosmis Racing 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-7 Turbo builds come through WheelFront every month, but this one stands out. The combination of the exterior with the Cosmis Racing MR7 creates a look that balances aggression with elegance.
Fitment Breakdown: Cosmis Racing MR7 on the Mazda RX-7 Turbo 1987
I walked around this FC RX-7 at the meet, and the setup stopped me cold. Running 18x9 all around with a +25 offset creates a serious stance on this chassis. It fills those wheel wells perfectly without looking like a monster truck.
The +25 offset on an 18x9 wheel pushes the face out right to the edge of the fender. You get that aggressive look we all crave on the FC. It sits flush without needing massive pull on the sheet metal.
Caliper clearance is always the big worry with older Mazdas. Thankfully, the MR7 spoke design creates plenty of room for upgraded brakes. You won't face any annoying interference issues here.
The hub bore fits the RX-7 platform like a glove. We love wheels that don't need sketchy hub-centric rings to stay vibration-free. Everything feels tight and purposeful.
The barrel lip depth on this 18x9 setup provides just enough detail to catch the eye. It isn't a deep-dish wheel, but it provides a clean, modern aesthetic. The proportions match the wedge shape of the 1987 body style perfectly.
Because the owner installed stiff coilovers, the suspension travel is kept in check. Without those coilovers, you might deal with some rubbing on the inner fender liners. Dialing in the damping is the only way to keep this setup functional.
Watch your front fender liners during tight parking maneuvers. If you go too low, the tires will kiss the plastic under load. Keep the alignment specs tight to maintain that sharp turn-in feel.
What We Recommend for Mazda RX-7 Turbo 1987 Owners
If you want this look, start with the 18-inch diameter. Anything smaller gets lost under the long lines of the FC. The 9-inch width is the sweet spot for a square setup that handles well.
Stick to offsets between +20 and +25 for the best visual impact. Going lower than +20 will force you to roll your fenders aggressively. Nobody likes hacked-up wheel arches on a clean RX-7.
We prefer a square setup on the FC for better tire rotation and predictable handling. Staggered builds look cool, but they introduce understeer you don't want on a track day. Keep it simple and keep it fast.
Do not skip the fender roll if you plan on lowering the car significantly. Even with the right offset, a sudden bump can catch the lip of the fender. Protect your paint before you head out for a spirited drive.
Use a quality tire with a slightly rounded sidewall to avoid rubbing. A 245/35/18 is a fantastic choice for this wheel width. It creates a clean transition from wheel to road.
Style and Build Analysis
The Gunmetal finish on these MR7s creates a moody, industrial look. It plays beautifully against the classic factory paint of this 1987 Turbo model. It isn't loud or flashy, but it demands your attention.
The multi-spoke design of the Cosmis MR7 bridges the gap between retro and modern. It pays homage to the era of the car while upgrading the tech. It makes the RX-7 look like it could have rolled out of a drift garage yesterday.
Proportion is everything with this car. The 18-inch wheels fill the arches just enough to kill the gap without looking cartoonish. The stance is level, purposeful, and ready for a mountain run.
We see a lot of builds with overly aggressive, fragile wheels. This setup feels robust and built for actual driving. You can see the driver treats this car as a machine, not a museum piece.
Compared to the typical flat-faced wheels we see on FCs, this choice adds dimension. The spokes have a slight concave shape that draws the eye toward the center cap. It is a masterclass in clean, effective modification.
Why We Love This Build
Seeing this RX-7 under the afternoon sun hit differently. The Gunmetal finish catches the light, showing off the intricate spoke work of the MR7s. It fills those arches with such authority that the car looks twice as fast just sitting still.
We love this build because it honors the soul of the Mazda RX-7 Turbo. It avoids the cheap trends and sticks to a proven, aggressive fitment that actually performs on the street. It is a clean, honest build that captures the spirit of the eighties.
This car reminds us why we fell in love with Japanese sports cars in the first place. When you nail the fitment, the entire silhouette of the car changes. Go get yourself a set and transform your ride.

Before You Buy: Fitment Checklist
We talk to Mazda RX-7 Turbo 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 Mazda RX-7 Turbo? 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-7 Turbo owners run 18×9 / 18×9-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
