Details

The SHIROKAI 2005–2009 Mustang S197 Widebody Kit is engineered for the first-generation S197 Ford Mustang platform, giving GT, V6 and Shelby GT500 builds real width, stronger presence, and more room for an aggressive wheel and tire setup — while still following the factory body lines.

This is not just an fender flares kit. Each SHIROKAI Mustang S197 widebody kit is CAD-engineered from platform-specific 3D scan data for cleaner fitment, better proportions, and less fabrication drama during installation. Made from premium automotive ABS plastic, this is the original SHIROKAI widebody kit — the one that started the SHIROKAI Army.

2005–2009 Mustang S197 Widebody Kit by SHIROKAI

Starting in 2019, a team of industry professionals wanted recognizable design and a new way to reimagine automotive styling — accurate but aggressive widebody kits with fewer compromises than serial car designers face. The first car we wanted to play with was the 2005–2009 Mustang; its bandit fascia gave a strong homage to the classic 60s models. Inspired by Mad Max and DTM, we kept a street-fighter look while following the stock lines. Using ten years of experience, 3D scanning, and CAD engineering for precision fitment — that’s when we grew into a community instead of just another online shop. The SHIROKAI Army was born.

Built for Street & Show

Each component follows the factory body lines closely, with minimal gaps when fitted correctly and smooth edges that reduce prep work. Wrap it from the box (light sanding + primer for paint). Built to handle the demands of both street and track — a complete visual transformation for owners chasing that bold 05 Mustang wide body attitude.

Frequently Asked Questions

Will this kit work on my Mustang Convertible?

Partially. The flares, side skirts, lip, and bumper endings all fit a 2005–2009 Convertible identically to the Coupe. However, the ducktail spoiler is excluded — Convertibles use a different trunk lid geometry that the spoiler doesn't match. Convertible owners typically order the kit without the ducktail spoiler option at checkout.

What about Shelby GT500 fitment (2007–2009)?

The GT500 uses a different front bumper than the standard GT. The kit fits with minor front bumper modifications — typically light trim work to mate the bumper endings cleanly with the flares. A competent body shop handles this in 1–2 extra hours during install. All other panels (flares, skirts, spoiler) fit identically to the GT.

Is this kit different from the 2010–2014 S197 kit?

Yes. The 2010–2014 facelift Mustang has different front bumper and front fender geometry, so it uses a separate kit. The 2005–2009 kit you're looking at is engineered specifically for the pre-facelift S197 body. If you have a 2010–2014, see our 2013–2014 S197 widebody kit.

How long does installation take?

Typical body shop install runs 12 to 16 hours including test fit, drilling, and rivnut setup. The install requires drilling holes in the fender for rivnut-mounted flares — this is standard procedure for properly secured aftermarket widebody and shouldn't be attempted without the right tools. We provide a step-by-step install guide on our blog as a reference.

Will my doors still open with the flares installed?

Yes. The flares follow the factory door cutline. Both doors remain fully operable at any opening angle. The kit does not interfere with door handles, mirrors, or fuel filler door operation.

What wheel and tire setup works with this kit?

240 mm of total added width supports significantly wider wheel and tire setups than stock — typically 18x11 or 19x11 wheels with 295–315 mm tires in the rear, and 18x10 or 19x10 with 275–285 mm tires up front depending on offset preference. Use our Widebody Wheel Fitment Calculator for precise sizing tailored to this kit.

Why is this priced lower than the 2013–2014 kit?

The 2005–2009 kit was our original widebody design from 2019 — manufacturing tooling has been amortized over years of production, and we pass that cost difference through to the price. Quality of ABS, manufacturing process, and fitment standards are identical to our current generation kits. You're getting the same engineering at our most accessible price point.

FAQs

Do body kit parts need prep before installation?

Yes. Widebody and body kit parts should be test-fitted, prepped, and installed by a professional body shop. Minor sanding or trimming is normal for custom builds across the aftermarket.

How long does a full body kit install take?

Several days at a body shop. Mounting is one part — prep, paint, and final assembly take the most time.

Will body kit parts fit if my car has had bodywork before?

Aftermarket body parts are designed for OEM panel dimensions. If your car has aftermarket fenders, frame damage, or non-stock panels, fitment may need adjustment. Send us photos before ordering and we'll flag anything to watch for.

Can I order parts of the kit separately?

Yes. Most body kit components are sold individually as well as in full kits. Message us if you want help mixing components from different kits to create your own setup.

Frequently Asked Questions

How do I know this will actually fit my car?

Every part listing shows compatible years, models, and trims. But here's the thing—trim packages and factory options can be confusing. If you're not 100% certain, text us at 772-277-2495 with your VIN or photos of your car. We'll verify fitment before you order so you're not stuck with an $800 part that doesn't fit. We've done this for 30,000+ builds. We've seen every weird trim combo and factory option. Takes us 2 minutes to verify, saves you weeks of headaches.

What if the part arrives damaged or is the wrong item?

We handle it. You don't fight with freight companies or file claims. Text us photos within 48 hours of delivery. If it's damaged or wrong, we ship a replacement immediately. You're not waiting 6 weeks for a freight claim to process. We eat the cost, not you. This is why we package everything like it's going to war. But if something slips through, we fix it ASAP. No forms, no back-and-forth, no "file a claim and wait." Just text us and we handle it.

Can I install this myself or do I need a shop?

Depends on the part. Emblems, front lips, some spoilers, bolt-on, DIY-friendly, you can do it in your driveway with basic tools. Full bumpers, hoods, wide-body kits, possible for experienced DIYers but most people take them to a shop for paint and install. Check the product description for installation difficulty. If you're unsure, text us. We'll be honest about whether you can handle it or if you should take it to a pro. We'd rather you know upfront than get frustrated halfway through.

What's your return policy if it doesn't fit or I don't like it?

30 days, unused parts in original packaging. You pay return shipping unless we sent the wrong part or it arrived defective. Once you install it, modify it, paint it, or mount it, we can't take it back. That's why we push so hard on verifying fitment BEFORE you order. We don't want you stuck with something you can't use. Text us before ordering if you're unsure. We'll confirm fitment so you never have to worry about returns.

Do you offer financing?

Yes. Affirm and Shop Pay available at checkout for orders over $50. Split payments over 3-12 months depending on order size. No hard credit check to see your options. Most people use this for big-ticket items like body kits, suspension setups, or wheel/tire packages. Rates vary based on credit. You see the monthly payment before you commit. Makes it easier to build now instead of waiting months to save up.

What if I have questions after I receive the part?

Text 772-277-2495. We don't disappear after you buy. Fitment questions, installation issues, "does this bolt go here" questions... we'll walk you through it. We've installed these parts ourselves or helped hundreds of people install them. You're not getting transferred to a call center in the Philippines. You're texting someone who's actually installed your part before. If we can't help remotely, we'll recommend a local shop that knows these parts.

Why should I buy from K2 instead of eBay/Amazon/other sites?

eBay and Amazon sellers don't answer fitment questions. They don't verify your VIN before shipping. They don't handle freight damage claims for you. If something goes wrong, you're filing disputes and waiting weeks. We're builders selling to builders. We verify fitment before you order. We handle damage claims same-day. We answer texts in minutes. We're not the cheapest, but you're not gambling $800 on whether a part fits. You're paying for support, verification, and someone who cares if your build goes sideways.

What does your warranty cover?

1 year against manufacturing defects: cracking, warping, paint peeling, hardware failure, fitment issues caused by the part being made wrong. Does NOT cover installation damage (you cracked it bolting it on), road damage (curb rash, rock chips), or normal wear. If it breaks because we made it wrong, we replace it free. If it breaks because you hit a parking block, that's on you. We're fair about it. Send photos and we'll tell you honestly if it's covered.

Shipping

Do you ship overseas?

Yes, we ship all over the world. Shipping costs will apply, and will be added at checkout. We run discounts and promotions all year, so stay tuned for exclusive deals.

How much does shipping cost and when will I see the total?

Depending on where you're located, small parts can ship free. Large parts like bumpers, hoods, and body kits require freight shipping. Uou'll see the exact cost at checkout before you pay. Freight usually runs $150-$300 depending on size and your location. We know it's expensive. We negotiate the best rates we can. If you're ordering multiple large parts, text us. We can sometimes combine shipping and save you money. We're not hiding fees in the final step. What you see at checkout is what you pay.

How long will it take to receive my order?

It depends on where you are. Orders processed here will take 5-7 business days to arrive. Overseas deliveries can take anywhere from 7-16 days. Delivery details will be provided in your confirmation email.

Took 2 weeks to deliver with standard shipping. But well worth the wait. Install took 25 minutes with minimal tools and the lights look amazing. Fitment is perfect and the quality is excellent. Its kinda pricey but you get what you pay for with ntxglow products. Highly recommend!

Customer photo review of Spec-D Projector Headlights Ford F150 (04-08) Mark LT (06-08) Halo Black / Smoked / Chrome

They look amazing, and after using ChatGPT to help me understand how to install them (because the instructions were not very helpful whatsoever), I’m glad with how they turned out. My problems are that the lights aren’t too bright, the instructions weren’t helpful, and the arrival date was wrong, even if they arrived early.

Customer photo review of 1993-1997 Honda Del Sol Redclear Tail Light Lenses

This isn’t on K2, but the lenses came In which I was thrilled about. I’d already removed my OEM lenses from their housings. The passenger side lense fit well and mostly flush. The driver side, however, looks like it was slightly warped and caused poor fitment and what looks like a small dip in the red portion of the lense. I had no choice but to use them, as my OEM lenses were no longer usable. It can be very difficult to get replacement lenses in a timely manner for a Del Sol. I drive my car everyday, so I had to just go with it. Again, not a K2 issue but presumably the manufacturer.

This rear bumper fits great the only thing is the trunk button on the bottom is cut a little to wide but that’s an easy fix it looks great and definitely makes the rear look more aggressive. I love it!

Customer photo review of Upgraded VANOS Oil Supply Line – M52 / M54 Engines (E36, E46, E39, E60, X3, X5, Z3, Z4)

The box was a little crushed, but the line was packed well and it wasn't a problem. The instructions are 3 pages of color pictures and lots of explanations. Very nice. The line itself is a very nice bit of kit with a swivel AN line end that allows a No-tension install. No leaks so far and it looks great. It came with new banjo bolts and copper crush washers. The only criticism I have is that I would have liked this hose coated in black so it disappears like the original, but it does look good, so I don't mind.
