About This Mazda RX-7 S 1979 Build
We love featuring real builds from real owners. This Mazda RX-7 S 1979 sits on a set of 15×7 / 15×7-inch Konig Rewind wheels, and the result speaks for itself.
The owner chose Konig 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 S builds come through WheelFront every month, but this one stands out. The combination of the exterior with the Konig Rewind creates a look that balances aggression with elegance.
Fitment Breakdown: Konig Rewind on the Mazda RX-7 S 1979
I saw this 1979 RX-7 S in the wild, and the fitment absolutely floored me. The owner chose the Konig Rewind in a 15x7 setup on all four corners. That square configuration brings a perfect balance to the narrow body lines of the SA22C chassis.
The 20mm offset lands exactly where it needs to be for this vintage platform. It pushes the wheels out just enough to kill that sunken, factory look without demanding a widebody kit. You get a nice, flush profile that honors the original design while adding some modern aggression.
Caliper clearance on these early RX-7s can be a headache, but the Rewind design handles it well. I looked closely at the front hubs, and the spokes clear the factory brakes with room to spare. You will not need aggressive spacers just to keep the wheels spinning freely.
The barrel lip depth on a 15x7 with a 20 offset is surprisingly deep for such a small wheel. That classic eight-spoke look creates a sense of depth that draws your eye straight to the hub. It feels purposeful and track-ready rather than just flashy.
This car sits on lowering springs, which tightens that fender gap significantly. Because the 15x7 is relatively conservative, we saw zero rubbing during hard cornering. The tire tucks neatly under the arch without shredding the fender liners.
Hub bore fitment is spot on, so you avoid the vibration issues common with cheap adapters. Everything bolts up tight, keeping the steering feel crisp and responsive. It is a textbook example of how to modify a classic Japanese sports car.
What We Recommend for Mazda RX-7 S 1979 Owners
If you want this look, stick to the 15-inch diameter. Going larger ruins the era-correct aesthetic and makes the car ride like a brick. The 15x7 is the sweet spot for handling and tire availability.
Don't even think about a staggered setup on this car. These early RX-7s handle best when you keep the footprint consistent front to rear. A square 15x7 setup allows you to rotate your tires and keeps the turn-in predictable.
Watch your tire choice carefully when running this offset. A 205/50/15 tire is my top recommendation for this setup. It provides a meaty look without ballooning over the edge of the rim.
Avoid the temptation to slap on massive spacers to chase "poke." You will end up rolling your fenders until the paint cracks, and the handling will go to hell. Let the 20 offset do the heavy lifting for you.
If you find that the stance still feels a bit tucked, a 3mm slip-on spacer is the absolute limit. Anything thicker changes your scrub radius too much. Keep it simple and let the wheel design do the talking.
Style and Build Analysis
The custom finish on these wheels is the star of the show. It contrasts beautifully against the factory paint, giving the car a sophisticated, custom-built vibe. It avoids the cheap look that often comes with mass-produced silver finishes.
The Konig Rewind is a love letter to the Watanabe wheels of the seventies. On this RX-7, the design feels like it rolled off the assembly line that way. It bridges the gap between vintage charm and modern performance perfectly.
Proportions are everything on a car this small. The 15-inch wheels fill the arches just enough to give the car a hunkered-down, purposeful stance. It looks like a period-correct circuit racer that somehow found its way onto the street.
I have seen dozens of RX-7 builds, but most get the wheel choice wrong. They either go too modern or too wide, turning the car into a cartoon. This build remains faithful to the original silhouette while upgrading the presence.
When the sun hits the custom finish, the car really pops. You see the light dancing across the spokes, highlighting the craftsmanship of the wheel design. It turns an already beautiful car into a complete work of art.
Why We Love This Build
This RX-7 captures everything that makes the early Mazda platform special. The custom finish on the Rewinds catches the light, while the 15-inch stance gives the car a grounded, muscular look. It is a masterclass in tasteful, restrained modification.
Seeing it parked under the streetlights, I knew it was something special. The wheels fill those arches with purpose, signaling that this car is built to be driven, not just shown. It reminds me why we fall in love with these machines in the first place.
If you want to transform your own SA22C, stop overthinking it and go with this exact setup. It is a timeless look that never goes out of style. Sometimes, the simplest path is the fastest way to perfection.

Before You Buy: Fitment Checklist
We talk to Mazda RX-7 S owners every day. These are the questions we hear most before they pull the trigger on new wheels.
Will 15×7 / 15×7-inch wheels fit my Mazda RX-7 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 Mazda RX-7 S owners run 15×7 / 15×7-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
