GReddy Pandem Wide Body Kits: Complete Guide for RX-7, Supra & More

If you know JDM performance culture, you know Pandem. GReddy's wide body program has produced some of the most recognized aero kits in the world — fender flares, aggressive front bumpers, GT wings, and complete over-fender systems that define the visual language of the modern Japanese performance scene. The Pandem kits are not bolt-on styling accessories. They're engineered aero packages designed to accommodate stretched and staggered wheel setups, with fitment tolerances that require proper installation.

This guide covers what GReddy Pandem makes, which platforms they build for, and what you need to know before purchasing a kit for your build.

Who Is GReddy?

GReddy (Trust Japan) was founded in Japan in 1977 and has been one of the most recognized Japanese aftermarket performance brands for nearly five decades. Their catalog spans turbochargers, exhaust systems, intercoolers, engine management, and aero — a genuine full-build brand with deep roots in motorsport and tuner culture.

Pandem is GReddy's dedicated aero and wide body division. The name and the distinctive over-fender style gained international recognition through collaboration with Kei Miura — the designer behind the "Rocket Bunny" aesthetic that dominated show cars and time attack events across the 2010s. GReddy and Rocket Bunny's creative overlap produced some of the most photographed JDM builds in the world, and the influence of that visual language is still visible in the JDM scene in 2026.

What's Included in a Pandem Wide Body Kit?

Kit contents vary by platform, but a typical Pandem wide body kit includes:

• Front bumper / front fascia — Aggressive lower front with integrated canards or splitter elements
• Front over-fenders — Bolt-on or bonded fender extensions that add 30–90mm of width per side depending on the kit
• Rear over-fenders — Matching rear fender extensions, typically wider than the front to accommodate rear tire fitment
• Side skirts / side steps — Body-color matched side extensions that complete the wide-body silhouette
• Rear bumper / rear diffuser — Not all kits include a rear bumper; some are fender-only kits
• GT wing or trunk spoiler — Optional on most kits; available as a separate component
• Hardware and mounting provisions — Bolts, clips, and mounting instructions

Material is typically FRP (fiberglass reinforced plastic) or CFRP (carbon fiber reinforced plastic) for premium/lightweight versions. FRP kits are the standard offering; carbon versions are available on select platforms at higher price points. All Pandem kits require professional fitting, sanding, and painting — they're not designed to be installed without bodywork experience.

Pandem Kits by Platform

Mazda RX-7 FD3S

The FD3S Pandem kit is one of the most iconic in the entire lineup. The FD's long hood, sloping roofline, and pop-up headlights make it one of the best canvases for the Pandem over-fender treatment. The FD3S Pandem kit adds substantial width front and rear, enabling wheel fitments that are simply not possible in stock body configuration. For track-built FD3S builds, the Pandem kit combined with the RaceOnly billet oil and engine components represents the complete approach to building one of these cars properly.

Mazda RX-7 FC3S

The FC3S Pandem kit was one of the original Rocket Bunny-era kits that put the collaboration on the global map. The second-generation RX-7's boxy, angular body responds beautifully to the aggressive over-fender treatment — the contrast between the original factory lines and the Pandem fenders creates the visual tension that defines the style. FC3S kits are available in multiple versions including a V2 with revised front bumper design.

Toyota Supra A80 (JZA80 / MK4)

The A80 Supra Pandem kit is among the most recognized wide body kits ever produced. The MK4 Supra's proportions — long hood, wide rear, and flowing bodywork — amplify the Pandem treatment dramatically. A full Pandem A80 kit with wing-equipped aero on a 1,000whp 2JZ build has become one of the archetypes of the modern JDM build scene. Multiple kit versions exist for the A80, including options with and without the iconic elevated GT wing. Browse our JZ-series engine and build parts to complement your A80 build.

Toyota GR Supra A90 (2020+)

GReddy released Pandem kits for the A90 GR Supra as the model entered production. The B58-powered A90 represents a different build philosophy from the 2JZ era, but the Pandem wide body treatment gives it the visual presence the factory car arguably lacks. The A90 Pandem kit is available in multiple versions as the model has been updated, so verify fitment for your production year.

Nissan GT-R R35

The R35 GT-R Pandem kit is one of the boldest in the catalog. The R35's already-wide factory body is transformed into something far more aggressive by the Pandem over-fenders and front bumper redesign. R35 GT-Rs built for time attack and show use frequently run the Pandem kit paired with large aero packages. The width accommodation allows for aggressive wheel fitments that complement the GT-R's AWD grip platform.

Nissan S-Chassis (S13, S14, S15)

Pandem and Rocket Bunny produced wide body kits for all three generations of the S-chassis: S13 (240SX hatchback and coupe), S14 (240SX 1995–1998), and S15 (Silvia, JDM market). The S-chassis kits are among the most affordable Pandem offerings and are extremely popular in the drift and street build communities. Multiple "versions" exist for each chassis with different front bumper and fender designs, so research the specific version number that matches your preferred aesthetic before purchasing.

Honda / Acura Platforms

Pandem also produces kits for select Honda/Acura platforms including the Honda S2000 (AP1/AP2) and NSX (NA1). The S2000 Pandem kit is particularly sought after given the platform's continued popularity in track and autocross communities.

FRP vs. Carbon Fiber: Which Version to Buy

Most Pandem kits ship in FRP as the standard material. FRP is paintable, repairable, and available at a lower cost than carbon. For street builds and show cars where appearance is the priority, FRP is the correct choice — it allows a seamless color match with the factory body.

Carbon fiber versions, where available, offer weight reduction and visual carbon weave. For track and time attack builds where every kilogram matters and a raw carbon look is acceptable, carbon is the upgrade. The weight savings are meaningful on GT wing components (GT-R, A90, A80) where a large carbon wing versus FRP wing can be 2–5kg lighter.

What to Budget For Beyond the Kit

The kit purchase price is the beginning, not the total cost of a Pandem build. Realistic additional costs:

• Bodywork and paint: Professional installation, surface prep, and full respray to match the new panels to the car's existing color typically runs $3,000–$8,000 depending on painter and complexity
• Wheel and tire fitment: The purpose of wider fenders is to run more aggressive wheel fitments. Budget for new wheels with appropriate offset and width, and tires sized for the new track
• Suspension adjustment: Lowering springs or coilovers adjusted for the new ride height that visually complements the wide body stance
• Brake line extensions: Some platforms require brake line modifications when running extreme negative offset wheels

Frequently Asked Questions

Are GReddy Pandem kits street legal?

Wide body kits do not inherently make a car illegal for street use in the US, but the wheel fitments and tire configurations that Pandem kits are designed to accommodate (extreme negative offset, stretched tires) may create issues in some states. The kit itself — bumpers, fenders, side skirts — is legal in most jurisdictions. Consult local regulations for your state.

How much does a Pandem kit cost?

Pandem kit pricing varies significantly by platform and version. S-chassis kits (S13, S14, S15) typically start in the $2,000–3,500 range for FRP. FD3S, A80, and R35 kits in the $3,500–6,000+ range. GT wing components are typically $800–1,500+ separately. Carbon versions carry a significant premium over FRP.

Can I install a Pandem kit myself?

The over-fenders and some bolt-on components can be self-installed by someone with fabrication experience. However, for a proper result that includes painted and blended panels, professional bodywork is required. The quality of the installation and paint determines the quality of the finished build.

What is the difference between Pandem and Rocket Bunny?

Rocket Bunny is the brand associated with designer Kei Miura, who collaborated with GReddy on many of the original wide body kits that defined the aesthetic. In practice, "Pandem" and "Rocket Bunny" kits for many platforms are the same products produced through the GReddy collaboration. GReddy continues to produce Pandem-branded kits independently as well.
