Review IMPROVED RACING Mazda Adjustable Sway Bar Links fits MIATA 1990–1997

The **Racing SMA-117 Sway Bar Links** are a meticulously engineered, high-performance upgrade designed exclusively for the **1990-1997 Mazda MX-5 Miata**, offering a dramatic improvement in handling precision, stability, and cornering confidence. Crafted from **heat-treated, high-strength steel**, these links are precision-machined to exacting tolerances, ensuring uncompromising durability and resistance to fatigue under extreme loads. Unlike stock sway bar links, which are often prone to flexing and premature wear especially under aggressive driving conditions the SMA-117 components feature **reinforced bushings** and a **stiffer, more rigid construction**, significantly reducing body roll and enhancing the Miata s natural agility. Whether tackling tight, technical corners at the track or pushing the limits on the road, these links deliver a **tighter, more responsive chassis geometry**, allowing the driver to extract every ounce of performance from the NA or NB-series Miata s lightweight chassis. The **direct-fit design** ensures a seamless installation, requiring no modifications to the existing sway bar assembly, while the **sleek, low-profile construction** maintains an unobstructed aesthetic without sacrificing performance. Ideal for both **track-focused enthusiasts** and **high-speed road drivers**, the SMA-117 sway bar links are a proven upgrade that transforms the Miata from a nimble street car into a **corner-carving, stability-focused machine**, making them a staple in the aftermarket for those seeking a balance of strength, precision, and reliability.

### Pros and Cons of Buying Racing SMA-117 Sway Bar Links for a 1990-1997 Mazda Miata

1. **Improved Handling and Stability** Sway bar links enhance cornering performance by reducing body roll, making the car feel more planted and responsive. This is particularly noticeable in aggressive driving or track use.

2. **Better Weight Distribution** Racing-grade links are often made from high-quality materials (e.g., billet aluminum or forged steel) and are precision-machined, which reduces unnecessary weight while maintaining strength.

3. **Durability and Longevity** SMA-117 links are designed for high-performance applications, meaning they can withstand the stresses of track use or hard cornering without premature failure. They are also less likely to stretch or wear out quickly compared to OEM parts.

4. **Compatibility with Other Upgrades** If you ve already installed other performance parts (e.g., stiffer springs, sway bars, or suspension components), these links will integrate well and complement those upgrades.

5. **Adjustability (if applicable)** Some aftermarket sway bar links allow for slight adjustments in length or angle, which can fine-tune the car s handling characteristics to your preference.

6. **Aesthetic Appeal** Racing-grade parts often have a cleaner, more polished look compared to stock components, which can enhance the car s sporty appearance.

7. **Reduced Body Roll** For drivers who frequently push the car hard, these links help minimize excessive body lean, improving tire grip and overall feel.

8. **Warranty and Support** Reputable manufacturers like SMA often provide warranties and customer support, giving you peace of mind in case of defects or installation issues.

1. **Cost** Racing-grade sway bar links are significantly more expensive than OEM or basic aftermarket alternatives. For a 1990-1997 Miata, a full set (front and rear) from SMA-117 can cost between $200 and $400, depending on the exact model and whether they include hardware.

2. **Installation Complexity** While not overly difficult, replacing sway bar links requires some mechanical skill and access to the correct tools (e.g., torque wrench, C-clamps, and possibly a press for stubborn bushings). If you re not comfortable with suspension work, labor costs at a shop will add to the expense.

3. **Potential for Overkill** If you primarily drive the car on the street or lightly on the track, the performance gains from SMA-117 links may not be noticeable enough to justify the cost. For casual drivers, a mid-range aftermarket set (e.g., from Tokico or Eibach) might suffice.

4. **Compatibility Issues** Ensure the links are specifically designed for your Miata s generation (NA, NB, or NC) and any other modifications you ve made (e.g., lowered suspension, different sway bars). Mismatched parts can lead to binding or improper fitment.

5. **Maintenance Requirements** While durable, these links may require periodic inspection for wear on bushings or bolts, especially if you drive aggressively. Rust or corrosion can also be an issue if the car is exposed to harsh conditions.

6. **Limited Aftermarket Support** Unlike OEM parts, SMA-117 links may not have as many readily available alternatives or upgrades (e.g., adjustable links) if you later decide to modify the setup further.

7. **Potential for Binding** If the links are not properly aligned or if the car s suspension geometry is altered (e.g., by lowering springs), they could bind under heavy cornering, leading to unusual noises or handling quirks.

8. **Resale Impact** While high-quality parts can appeal to enthusiasts, the resale value of a Miata with racing-grade sway bar links may not be significantly higher than one with stock or basic aftermarket parts, depending on the buyer s priorities.

Racing SMA-117 sway bar links are an excellent choice for owners of a 1990-1997 Mazda Miata who prioritize **performance, durability, and a track-ready feel**. They offer measurable improvements in handling, stability, and responsiveness, making them ideal for drivers who frequently push their cars hard or use them on the track. The investment is justified if you ve already committed to a performance-oriented build or if you re looking to maximize the car s potential in cornering.

However, if you re a **casual driver** or on a tight budget, the cost and complexity may not be worth it. In such cases, a **mid-range aftermarket set** (e.g., Tokico, Eibach, or Ohlson) could provide a good balance of performance and affordability without the premium price tag. Additionally, if you re unsure about installation or lack mechanical experience, factor in labor costs or consider learning the process yourself.

Ultimately, the decision depends on your **driving goals, budget, and how aggressively you plan to use the car**. For those who want the best possible handling and are willing to invest in high-quality parts, SMA-117 links are a strong recommendation. For others, a more modest upgrade may be sufficient.

- You drive your Miata aggressively on the street or track.

- You ve already installed other performance suspension components (e.g., stiffer sway bars, springs, or bushings).

- You value durability and precision in your parts.

- You re comfortable with or can afford professional installation.

- You re a casual driver and don t need extreme performance gains.

- You want to save money and are open to mid-range aftermarket options.

- You re unsure about installation and prefer to avoid complex suspension work.

For most enthusiasts who want a **track-ready or high-performance street car**, the SMA-117 links are a worthwhile upgrade. Pair them with proper installation and maintenance for the best results.
