GT Spirit's 1:18 resin Mazda RX-7 FD3S wears Liberty Walk's LB Super Silhouette widebody kit in a Renown-inspired bi-colour livery, a tribute to Mazda's early 1980s Super Silhouette racing era. Flared box arches, deep front and rear aero and a two-tone split give the FD3S a genuinely different silhouette from a stock car. Built as a sealed, one-piece resin body, the casting holds crisp, continuous panel lines around the widened arches, letting the tuner's aggressive stance read cleanly from every angle on a display shelf.
About the Mazda RX-7 FD3S LB-Works LB Super Silhouette Renown Bi-Color GT Spirit 1:18
TL;DR: GT Spirit's 1:18 resin Mazda RX-7 FD3S wears Liberty Walk's LB Super Silhouette widebody kit in a Renown-inspired bi-colour livery, echoing Mazda's early 1980s Super Silhouette racers. Built as a sealed, one-piece resin body with no opening panels, the flared box arches and two-tone split give this tuner special a distinctly aggressive shelf presence.
Liberty Walk built its LB Super Silhouette range specifically as a tribute to Japan's late-1970s and early-1980s silhouette racing formula, a category that produced some of the most flamboyant widebody race cars ever to compete. This FD3S carries that homage directly, its box-flared arches and Renown-inspired two-tone livery deliberately recalling the Mazda Savanna RX-7 racers that competed under similar sponsorship colours during that era.
Super Silhouette Racing and Liberty Walk's Tribute
A Racing Formula Built for Flamboyant Widebody Cars
Japan's Super Silhouette category ran through the late 1970s and early 1980s as a showcase for extreme widebody race cars built loosely on production silhouettes, with manufacturers including Mazda, Nissan and Toyota fielding factory-backed entries wrapped in flamboyant sponsor liveries. Mazda's Savanna RX-7 competed in that scene, its box-flared arches and low, wide stance becoming an enduring reference point for Japanese tuning culture decades later.
Applying That Heritage to the FD3S
Liberty Walk built its LB Super Silhouette line as a deliberate homage to that era, applying similarly extreme box-flare widebody kits to modern platforms including the FD3S generation of RX-7, a car already known among enthusiasts for its rotary engine and pop-up headlamps. This particular casting carries a Renown-inspired bi-colour livery, a nod to the sponsor liveries that decorated period Super Silhouette racers, giving the model a genuine motorsport reference point rather than an invented paint scheme.
Resin Construction and the Widebody Silhouette
Casting the Bolted-On Arch Extensions
Liberty Walk's box-flare widebody kits work by bolting or riveting flared arch extensions over the stock bodywork, dramatically widening the car's stance without reshaping the underlying panels themselves, and reproducing that layered look convincingly in miniature requires a level of surface definition that favours resin over die-cast tooling. GT Spirit casts this FD3S as a sealed, one-piece body, and the construction pays off directly around the flared arches, where the transition between the stock bodyline and the bolted-on extension needs to read as a distinct panel edge rather than a smoothed-over blend.
Getting the Bi-Colour Split Right
Because there is no hinge or opening seam competing for space along those lines, the arch extensions, deep front splitter and oversized rear wing all hold sharp, consistent definition. The bi-colour livery adds another layer of difficulty: getting the split line between the two colours straight and consistent across every panel demands careful masking during finishing, and any wobble in that line would be immediately obvious against the kit's already dramatic proportions. Under a directed shelf light, the paint holds real depth across both colours.
Where This Tuner Special Sits in a Collection
Tuner-special reproductions occupy a different collecting lane from factory-stock models, appealing to buyers drawn to a specific aftermarket story rather than an original manufacturer specification. For a JDM-focused collection, this piece works as a bridge between two eras: the rotary-powered FD3S chassis from the 1990s and 2000s, and the Super Silhouette racing aesthetic it borrows from a decade earlier, brought together by a modern aftermarket specialist rather than either era's original manufacturer. Buyers who already own a stock FD3S reproduction will find this a natural companion piece, showing how far the aftermarket scene has taken a car Mazda designed nearly three decades ago.
A Standout Piece for a Tuner Shelf
This RX-7 works best in a display built around JDM tuner culture or Japanese motorsport heritage rather than a straightforward manufacturer chronology, where its widebody proportions and tribute livery can stand out rather than compete with more conservative stock reproductions. The sealed resin body holds the kit's sharp arch extensions and aero pieces with genuine precision, trading interior access for a silhouette that stays exactly as dramatic as the day it left the mould. For a collector who values the story behind a livery as much as the car itself, this FD3S delivers both in one distinctive package.
