After market auto parts are performance and style upgrades built by companies other than your car’s original manufacturer. High-quality choices—especially expertly-designed aerodynamic parts and carbon fiber components—let you push your vehicle’s look and performance far beyond factory limits.
Choose after market auto parts to get more customization, faster innovation, and access to the materials and designs used by passionate car enthusiasts worldwide. Whether you want targeted power gains, a unique style edge, or a true track-ready setup, after market options are your fastest path to real transformation.
Understand After Market Auto Parts: What They Are, Why They Matter
Let’s cut through the confusion around after market auto parts and why automotive enthusiasts turn to them for faster gains in both performance and style. You want more than basic replacements. You want customizable solutions, extra power, and attention-grabbing looks. Here’s what after market delivers.
Why After Market Parts Stand Out:
- Expanded choices: Find aerodynamic upgrades, carbon fiber kits, and finishes that OEM rarely offers. After market brands innovate fast, dropping new styles ahead of the factory curve.
- Customization, your way: Tailor power, handling, and appearance. No restrictions to a bland, factory look—boost your car to match your vision.
- High-impact materials: Enjoy the performance edge of carbon fiber, durable ABS, or forged alloys for measurable improvements in grip, weight, and downforce.
- Warranty confidence: Your factory warranty remains active unless an after market part is proven to cause damage. Document your installs—max protection, minimum hassle.
- Pro-level results: At ASM Design, we set our standard above generic brands by focusing on engineered fit, advanced finishes, and real-world test data. Our kits deliver not only visual impact but are built for speed and confidence.
Today’s premium after market parts offer both innovation and protection, so you can upgrade fast without compromise.
Set Your Goals: Define Performance, Handling, or Style
Before you buy new parts, get clear about what you want to achieve. Effective upgrades begin with disciplined planning. Decide what results will make you excited to drive your car every day.
The Power of Goal Setting
Ask yourself what you really want: More horsepower? Sharper cornering? A bold, new visual identity? This clarity puts you in control, prevents wasted spend, and helps track before-and-after gains.
- Track-focused performance: Prioritize intakes, exhausts, and ECU tunes. See measurable horsepower gains and reduce your 0–60 time. Stack these with carbon fiber body kits for additional weight savings.
- Superior handling: Upgrade to coilovers, larger brake kits, and lightweight wheels. Notice tighter grip and braking response on your next spirited drive.
- Show-stopping style: Install full aero kits, splitters, side skirts, and gloss black accents. Transform your presence at shows and on the street, fast.
Break goals into phases. Start with simple additions (splitters, mirror caps) for instant progress, then move toward high-impact upgrades like full aero or coilovers as budget allows. Always document your successes with before-and-after photos or simple lap times.
A clear goal and a straightforward checklist are the quickest route to results you can see and feel.
Compare After Market vs OEM: Which Is Right for You?
Every car owner wrestles with the choice—stick with OEM or level up with after market? For automotive enthusiasts, the decision comes down to value, creativity, and speed of upgrade.
Key Differences and Best Use Cases
- Cost and selection: After market brands give access to a bigger catalog. Want carbon fiber splitters or vented diffusers? You will find more options and often better pricing than direct-from-dealer parts.
- Performance and innovation: ASM Design leads with advanced materials, fitment guarantees, and rapid new product releases. Outfit your car with lightweight, precisely-engineered kits that set you apart immediately.
- Factory reliability: OEM parts excel for critical safety items and when you want a “stock” replacement. Use them when you must preserve 100% original spec, or your main goal is resale value stability.
- Warranty reality: Using high-quality after market parts like those from ASM won’t void your warranty unless proven to cause the issue. Review your service contract and keep paperwork organized to protect your investment.
OEM parts serve routine repairs. After market exists to deliver upgrades—higher-flow exhausts, premium aero, or lightweight wheels—where you want the biggest impact.
For stand-out looks, advanced materials, and the latest styles, after market is your shortcut to results factory parts can’t match.
Demystify the Main Types of After Market Auto Parts for Enthusiasts
Auto upgrades fall into several categories, each with unique benefits. Knowing what’s available—and what delivers the most return—helps you build without regrets.
Popular Types of After Market Parts
- Aerodynamic kits: These include splitters, spoilers, diffusers, and full-body kits. Carbon fiber versions dramatically reduce weight, sharpen your stance, and increase downforce for real handling gains.
- Exhaust systems: Upgrade to unlock a deeper sound, more power, and immediate throttle response. Match these with intake mods for stronger performance.
- Intake systems: Cold air intakes ramp up airflow, delivering a punchy, efficient engine feel. Combine with ECU tunes for noticeable results.
- Wheels and tires: Lightweight forged wheels drop unsprung mass. Pair with stickier tires and feel the difference in turn-in and acceleration.
- Lighting and accessories: From custom tail lamps to paddle shifters, these touches individualize your cabin and exterior without a full build.
Curated body kits and matched component bundles improve compatibility and give your car a unified, aggressive look. Our kits include all hardware and detailed install guides for turnkey results.
Choose aerodynamic pieces and carbon fiber as your upgrade foundation if you want the fastest and most dramatic transformation in performance and presence.
How to Choose the Right After Market Parts for Your Car
Getting the right fit is non-negotiable. The thrill is in a smooth install, flawless operation, and zero regrets post-upgrade. Here’s how we see successful enthusiasts navigate the selection process.
Step-by-Step Selection That Delivers
- Confirm fitment: Always check your make, model, year, and current spec. Miss this, and even high-end parts won’t fit right.
- Shortlist by goals: Compare brands, material quality, and reviews. Will this part deliver the power, handling, or look you expect?
- Read installation notes: Know what tools, hardware, or professional help you need before parts arrive.
- Leverage guarantees and support: At ASM Design, every part ships with guaranteed fitment, full instructions, and round-the-clock help so you never get stuck.
- Keep records: Save invoices, unbox parts immediately, and check for any shipping issues. Documentation protects your warranty and eases future mods or resale.
Fitment ensures you never waste money or time. Work step-by-step and always use suppliers who stand behind their kits with clear, honest policies.
The right parts, installed right, take your build from wishful thinking to show-stopping reality.
See the Results: Before-and-After Performance and Style Impact
This is where it all pays off. You want proof—not promises. When you bolt on high-quality after market auto parts, you see, feel, and even hear the difference from day one.
Drop in new carbon fiber splitters or a full aero kit, open the throttle, take the first sharp corner, and the results are clear.
Real-World Gains You Can Track
- Power made visible: Add an intake, exhaust, and tune. Dyno numbers go up. Throttle response is crisp. Even a conservative setup can cut 0–60 times noticeably.
- Handling that inspires: Lightweight wheels and our carbon fiber kits sharpen steering and boost grip. Upgraded brakes shrink stopping distances. Lap times fall.
- Visual punch: Before, your car looked stock. After, it turns heads. Body kits and gloss black pieces create a high-end finish seen in top-tier builds.
- Everyday pride: Your drive becomes an experience. Subtle upgrades—mirror caps, lips—refresh the look instantly and set the stage for your next phase.
Show your progress. Use before-and-after photos, track your best runs, and collect real reactions. What matters is repeatable, measurable change—not hype.
Document every install with photos and numbers—over time, you’ll track not just performance but also your own growth as an enthusiast.
Fast Track the Install: DIY or Professional Fitting Tips
Now, how do you get those results as quickly as possible? That comes down to smart installation. Should you handle upgrades yourself, or trust the pros? Here’s what we recommend for enthusiasts serious about both speed and quality.
Install Options—Pick the Fastest Path to Success
- DIY wins: Mirror caps, small splitters, or air filters are plug-and-play. Save money, learn about your car, and finish in an afternoon.
- Go pro for major mods: Full aero kits, suspension, or ECU work deserve expert hands. Shops ensure perfect fit, correct torque, and professional results.
- Installation kits matter: Our body kits come with all hardware, fitment instructions, and access to our support team—avoid lost weekends hunting bolts or guides.
- Typical times: Most bolt-ons take 2–4 hours. Big jobs or alignments may go full-day. Factor your own tools, skills, and workspace.
If the upgrade impacts safety or core performance, get help. Keep all install records—your warranty and resale value depend on it.
An expert install paired with the right parts lets you hit the road fast, confident nothing was left to chance.
Bust the Myths: Is After Market Quality Legit?
There’s no room for doubt. The right after market auto parts are just as reliable as (and sometimes better than) OEM items. Don’t let myths hold you back from real performance.
We take quality and fitment seriously at ASM Design. Every piece we create undergoes strict testing, exact finish checks, and repeated vehicle-specific trials.
How to Separate Quality from Hype
- Look for certified testing: Premium brands invest in material specs, impact checks, and wind tunnel testing for aerodynamic parts.
- Insist on warranties: We back our kits with clear, detailed warranty coverage. If a supplier can’t match that, skip them.
- Beware of knockoffs: Deep discounts, missing fitment data, or absent instructions are warning signs. Stick with trusted names.
- Ask for real-world results: Dyno charts, install photos, and lap time improvements reveal authenticity—no fluff, just facts.
Don’t be tempted by “cheap and easy.” You want proven, warranty-backed components designed for hard use and bold style.
When you choose brands that demonstrate transparency, you get upgrades that last.
Use the Upgrader’s Checklist: Confident Steps for Your Build
Planning pays off. Use these steps each time you add a part and you’ll avoid common mistakes.
The Enthusiast’s Pre- and Post-Upgrade List
- Pre-upgrade: Confirm fitment, review install guides, and clarify your goals for power, handling, or style.
- Upon arrival: Unpack, check for shipping damage, verify kits are complete, and dry-fit key parts before painting or final install.
- Post-upgrade: Run shakedown drives, track performance gains, and photograph results for your records.
- Insurance and service: Notify your insurer if your mods boost performance or value. Save all receipts for future claims or resale.
Keep things organized. Every smart step unlocks more enjoyment—and more confidence for the next phase.
Upgrades done with discipline always outshine those done in haste.
