After market auto body parts are components made by specialized manufacturers to upgrade your car’s style, aerodynamic performance, and driving feel—going beyond what factory options offer.
These parts, such as carbon fiber splitters, gloss black side skirts, and vehicle-specific diffusers, let enthusiasts customize their build with sharper looks and proven functional gains.
High-quality after market auto body parts deliver precise fitment, reduced weight, and true show-car appeal.
Choosing expertly engineered upgrades means no compromise on durability or warranty peace of mind.
In this article, you’ll see exactly what sets premium options apart, and which choices help your car stand out on the road and at the track.
Understand Why After Market Auto Body Parts Matter for Enthusiasts
You want a car that turns heads and performs. Upgrading with after market auto body parts is how real enthusiasts set themselves apart. It’s not about copying what others are doing; it’s about finding purpose-built components that express your unique taste and deliver results.
Core Motivations for Upgrading:
- Personal style: After market parts let you define a fresh look, stand out at shows, and differentiate your build. Dry pre-preg carbon fiber and gloss black ABS speak volumes without a single word.
- Performance goals: Precision engineering isn’t just cosmetic. Pre-preg carbon shaved using an autoclave drops weight and boosts stiffness, delivering genuine track-day confidence or daily comfort.
- Event presence: Owners who chase trophies at car events know that fitment and material quality win points.
- Avoiding generic headaches: You want more than a cheap copy. With ASM Design, our expert team provides guaranteed fitment and hardware that match your car from the start, removing frustrating surprises.
- Long-term satisfaction: When you invest in true craftsmanship and consider function as well as form, you experience a deeper sense of pride in your build.
If you’re serious about your car’s look and capability, your upgrade choices should be just as serious.
Know the Key Differences Between OEM and After Market Body Parts
Choosing between OEM and after market parts can feel complex for anyone, but it’s crucial for enthusiasts who push their cars and care about the details. Let’s break down exactly what sets these options apart so you can act with confidence.
Decoding Quality, Fit, and Options
OEM will always match original specs. After market parts can range in quality, but the best from specialists like ASM Design can actually exceed what the factory delivers. You get design freedom, advanced materials like autoclave-cured dry carbon, and precision-fit hardware that removes the guesswork.
If you care about warranty, OEM often keeps it intact. The best after market parts come with extensive coverage, documented processes, and their own fitment guarantees. That’s why our carbon kits and diffusers ship with factory-match mounting solutions and clear, legacy-proof support.
A Quick Comparison Table
- OEM: Perfect fit, keeps warranty, but limited design choices and material options.
- After Market: Wide range; top-tier brands offer better styling, lighter weight, and custom engineering. Fitment may vary by manufacturer.
- ASM Design: We fill the performance and fitment gaps, using tested materials and design to guarantee both reliability and satisfaction.
Explore the Main Types of After Market Auto Body Parts Available
The market offers endless variety, but not all parts meet the needs of serious car owners. Here’s how you can make sense of what’s out there and pick with purpose.
Key Categories and Their Real Impact
- Full body kits: Revamp your car’s entire shape, often with a weight or aero bonus. Best for show vehicles or radical builds.
- Front splitters: Deliver real downforce and visual bite. Properly mounted dry carbon splitters improve grip and balance.
- Rear diffusers: Optimize underbody airflow and stability, especially when paired with a matching splitter.
- Side skirts: Lock in airflow benefits and complete the lowered look.
- Spoilers and wings: Control rear-end lift and increase confidence at speed. Correct design and placement matter.
- Bumpers and mirror caps: Refine the road presence and update race-inspired lines. ABS is ideal for daily drivers seeking impact resistance.
- Interior and lightweight panels: Drop weight, simplify the feel, and keep your cockpit uniquely yours.
Style-only plastics work for looks, but real dry carbon or engineered ABS upgrades pull double duty for both form and function—critical for anyone who actually drives their build.
Analyze the Performance and Aesthetic Impact of After Market Body Parts
Making changes isn’t just about appearances. You’re aiming for a feeling, an edge, and data that proves the difference. The right parts, carefully selected and installed, offer clear gains on all fronts.
What Premium After Market Parts Can Deliver
- Weight loss: Swapping steel for carbon fiber hoods or trunks instantly lowers your car’s center of gravity and sharpens cornering.
- True aero: Splitters, diffusers, and wings from top manufacturers provide tested downforce, not just empty promises.
- Fitment precision: Choose bolt-on solutions built for your model, not universal pieces that need constant adjustment.
- Lasting value: High-quality pre-preg carbon stands up to repeated abuse without the yellowing or cracking of wet carbon or fiberglass.
- Street and event impact: Upgrades look aggressive and get noticed.
Every fit, finish, and fastener matters when you want to move from just show to real, measurable go.
Balance Style and Function: How to Choose the Right After Market Body Parts
Upgrading starts with clarity. You need to match the style to your goals and make sure it performs as well as it turns heads.
Rapid-Fire Checklist for Smart Selection
- Define your purpose: Show car, street style, track weapon—or a mix?
- Set your budget: Factor in installation, paint, and protection hardware.
- Check real-world fitment: Look for brands that show actual installed photos, hardware lists, and clear guides.
- Match model and year: Avoid one-size-fits-all. Precision matters.
- Research materials: Dry carbon for track, ABS or wet carbon for daily drivers and show builds.
- Prioritize durability: Ask about warranty, included hardware, and fitment guarantees.
- Start with smaller non-structural upgrades if you’re unsure, then scale up as you gain experience.
Choosing well takes discipline, not luck. Align parts to your driving style and aesthetic vision every step of the way.
Navigate Fitment, Installation, and Warranty for a Hassle-Free Experience
Success with after market auto body parts depends on more than selecting the right look. Fitment, installation, and solid warranty terms protect your time, money, and morale.
We know nothing kills momentum like poor fit or missing hardware. That’s why our process ensures you get professional results every step of the way.
What to Expect from a Quality Supplier
- Professional installation recommended: Trust certified techs for the cleanest fit, especially for structural or aerodynamic upgrades. This step preserves warranty and guarantees each piece is mounted as designed.

Buying body parts is only half the battle—proper support, guidance, and protection finish the job.
Compare Costs and Value: Are After Market Auto Body Parts Worth It?
Let’s talk numbers. Not all after market parts are created equal, but cheap options often fail in the long run. You’re looking for real return—not just upfront savings.
Premium dry carbon parts cost more, but offer unbeatable strength and a flawless finish. Wet carbon and fiberglass save money, but will always be heavier and less durable. Consider cost over the part’s lifetime, not just its sticker price.
Why Quality Pays Off
- Less time and cash spent correcting fitment issues
- Fewer replacements due to cracking or UV damage
- Higher resale value with proven, branded parts on the build sheet
- Peace of mind from strong warranty coverage
Factor in installation, paint, hardware, and possible customs/shipping fees. To maximize value, bundle upgrades, and invest once in parts that won’t let you down.
Debunk Common Myths and Fears About After Market Auto Body Parts
Plenty of shoppers worry about warranties, lousy fitment, or subpar quality. Let’s set the record straight with facts, not fears.
The truth: After market doesn’t have to mean “cut corners.” Many modern brands—like ASM Design—engineer parts that match or surpass OEM precision. Our products are model-specific, rigorously tested, and include comprehensive warranty and fitment guarantees.
How to Spot Red Flags Before You Buy
- Vague material or fitment info
- No support number or sketchy return policies
- No real-world install photos
- No warranty documentation
Stick with brands offering full transparency and proofs—not just fancy marketing photos. That’s how you get real peace of mind, not just hope.
Every quality-focused purchase reduces your risk and pays off in real satisfaction, day after day.
