About This Mazda RX-7 GTU 1988 Build
We love featuring real builds from real owners. This Mazda RX-7 GTU 1988 sits on a set of 17×9 / 17×9-inch STR 606 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-7 GTU builds come through WheelFront every month, but this one stands out. The combination of the exterior with the STR 606 creates a look that balances aggression with elegance.
Fitment Breakdown: STR 606 on the Mazda RX-7 GTU 1988
I walked around this RX-7 at the meet, and the setup stopped me cold. Running 17x9 STR 606s on all four corners creates a serious, aggressive stance. That square setup transforms the narrow FC chassis into something much more planted.
The 45 offset sits deep inside the wells, so we definitely need to watch that inner clearance. On the front, you risk hitting the coilover strut if you run too much tire width. I noticed the owner used a thin spacer to clear the front shock body perfectly.
The GTU brakes are decent, but these wheels offer plenty of clearance for the calipers. The barrel design leaves enough breathing room for the stock setup. You won't face any issues with the hub bore as long as you use the right centric rings.
Those 17-inch diameters fill the wheel arches way better than the factory 15-inch pizza cutters. The ride height sits low on those coilovers, which tightens up the whole look. You get a firm, connected feel through the steering wheel now.
The rear fitment looks tight against the inner fender liner at full compression. If you push the suspension hard, you might hear a little bit of rubbing on big dips. I suggest a slight fender roll if you plan on running meaty rubber.
The multi-spoke design of the STR 606 adds a classic race aesthetic to the FC body. These spokes feel sturdy and pull the eye toward the center cap. It is a timeless choice that feels right at home on an '88 model.
We see a lot of builds, but this specific offset choice keeps the wheels tucked neatly. It avoids that cheap, poke-heavy look that ruins the lines of an RX-7. This car looks like a proper weapon instead of a toy.
What We Recommend for Mazda RX-7 GTU 1988 Owners
If you want this look, start with your coilovers first. You cannot dial in a 17x9 setup without adjustable suspension components. Cheap springs will just leave you with uneven gaps and potential tire damage.
Don't be afraid to experiment with your offset, but stay between 35 and 45 for the best results. A 35 offset gives you a flush look without requiring massive fender modifications. We prefer that over aggressive poking every single time.
Staggered setups look fine, but a square 17x9 is the way to go for handling. You can rotate your tires and actually drive the car hard in the canyons. It makes the RX-7 feel balanced and predictable in the corners.
Tire choice matters more than people admit. Wrap these wheels in a sticky 235 or 245 width tire for the best grip. Avoid massive stretches because they ruin the contact patch and look dated.
Check your alignment after you bolt everything on. You need some negative camber to tuck the tops of those wheels properly. If you skip this step, you will shred your sidewalls on the first highway drive.
Style and Build Analysis
The Silver finish on these STR 606s pops against the factory paint. Silver is the ultimate choice for a clean, period-correct vibe. It looks classy under the bright stadium lights at the meet.
These wheels pull the whole build together. The FC RX-7 has soft, rounded edges, and these sharp spokes provide the perfect visual contrast. It stops the car from looking like a blob.
The stance sits low, but it remains functional. You can tell the owner actually drives this thing instead of just parking it at shows. It has a road-ready aggression that I really respect.
We see plenty of RX-7s running cheap, gaudy wheels that clash with the body. The STR 606 respects the original design language of the 80s. It feels like an evolution of the factory style rather than a total departure.
The proportions look spot on from every single angle. The 17s provide enough sidewall to maintain the right silhouette without looking like a wagon wheel. It is a masterclass in restrained modification.
Why We Love This Build
This RX-7 captures everything we love about the golden era of Japanese sports cars. The Silver STR 606s catch the sunset light perfectly as the car rolls into the parking lot. The way the wheels fill those arches makes the car look significantly wider and more purposeful.
Seeing this car in person reminded me why I fell in love with the FC platform in the first place. It is simple, effective, and damn near perfect. We love builds that elevate the stock lines without turning the car into a cartoon.
This is the exact blueprint for a street-driven legend that commands respect at any gathering. Go build yours right now.

Before You Buy: Fitment Checklist
We talk to Mazda RX-7 GTU owners every day. These are the questions we hear most before they pull the trigger on new wheels.
Will 17×9 / 17×9-inch wheels fit my Mazda RX-7 GTU? 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 GTU owners run 17×9 / 17×9-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
