Review BMW Oem 84-92 Rear 14.5mm Sport Sway Bar Stabilizer Mounts fits E30

The **BMW E30 84-92 Rear 14.5mm Sport Sway Bar Stabilizer Mounts** are a precision-engineered upgrade designed to enhance the handling dynamics and overall driving experience of your classic BMW 3 Series (E30) from the 1984 to 1992 model years. These mounts are meticulously crafted to replace the stock rubber bushings, which can degrade over time due to wear, heat, and constant stress from aggressive cornering or rough road conditions. By upgrading to these high-performance mounts, you eliminate the flex and slop inherent in the original components, resulting in a noticeably firmer and more responsive rear suspension. The 14.5mm diameter design ensures compatibility with stock or aftermarket sway bars, including those with slightly different specifications, making these mounts a versatile choice for both stock and modified setups. Constructed from durable, high-quality materials, these mounts are engineered to withstand the rigors of spirited driving while maintaining their structural integrity under heavy loads. Whether you're pushing your E30 through tight corners at the track or simply enjoying a more engaged, sport-tuned ride on the road, these mounts deliver a measurable improvement in cornering stability, reducing body roll and improving tire grip. The installation process is straightforward, requiring only basic tools, and the upgrade can be completed in minimal time, making it an accessible yet impactful modification for enthusiasts looking to refine their E30 s performance without compromising reliability. Perfect for both daily drivers and weekend track warriors, these rear sway bar mounts are a subtle yet effective way to elevate the driving dynamics of your beloved E30, ensuring a more precise, confident, and exhilarating ride.

### **Pros and Cons of Buying a 14.5mm Sport Sway Bar Stabilizer Mount for a BMW E30 (1984 1992) 335i (M135B30 Engine)**

1. **Improved Handling and Stability** A stiffer sway bar setup reduces body roll, especially during cornering, making the car feel more planted and responsive. This is particularly noticeable on winding roads or in aggressive driving situations.

2. **Enhanced Cornering Performance** The increased stiffness helps maintain tire contact with the road, reducing understeer and improving traction. This is beneficial for drivers who push the car harder or enjoy track-like conditions.

3. **Better Weight Distribution** The stock sway bar mounts can be soft, leading to uneven weight transfer. Upgrading to a sportier setup (like the 14.5mm bar with stiffer mounts) can help distribute weight more evenly, improving overall dynamics.

4. **Compatibility with Other Suspension Mods** If you ve already made other suspension upgrades (e.g., lower springs, stiffer shocks, or poly bushings), a sport sway bar setup will complement those changes by reinforcing the chassis.

5. **Aesthetic Appeal** While not a performance benefit, some drivers prefer the look of a sportier sway bar setup, especially if paired with other aftermarket suspension components.

6. **Potential for Future Upgrades** A 14.5mm bar is a common aftermarket size, meaning you ll have more options for future modifications (e.g., adjustable bars, different mount styles) without being locked into a niche part.

7. **Reduced Body Flex** The stock sway bar can flex excessively under hard cornering, leading to a "soft" feel. Stiffer mounts minimize this, making the car feel more rigid and composed.

---

1. **Harsher Ride Quality** A stiffer sway bar setup can make the car feel less comfortable on rough roads, bumps, or uneven surfaces. If you prioritize comfort over sportiness, this may be noticeable.

2. **Potential for Overcorrection** While reducing body roll can improve handling, an *overly* stiff setup (especially if paired with other aggressive mods) can lead to excessive understeer or a "stiff" feel, making the car less forgiving on imperfect roads.

3. **Compatibility Issues with Stock Components** Some aftermarket sway bar mounts may not fit perfectly with stock bushings or sway bar links, requiring additional modifications (e.g., cutting or replacing bushings). Ensure the mounts are designed for the E30 before purchasing.

4. **Cost of Installation** While the sway bar itself is relatively affordable, labor costs for installation (especially if you need to replace bushings or adjust linkages) can add up. DIY installation is possible but may require some mechanical skill.

5. **Limited Real-World Benefit for Daily Driving** If you primarily drive on smooth highways or in urban settings, the improvements in handling may not be as noticeable. The benefits are more apparent in spirited driving or track use.

6. **Risk of Damage to Other Components** If the sway bar is too stiff or not properly balanced, it could put extra stress on the subframe, bushings, or even the chassis over time, leading to premature wear.

7. **May Not Be a "Quick Fix" for Poor Handling** If your car has other suspension issues (e.g., worn shocks, bad bushings, or misaligned geometry), simply upgrading the sway bar won t fully resolve handling problems. A holistic suspension tune is often needed.

Upgrading to a **14.5mm sport sway bar with stiffer mounts** on your BMW E30 335i is a worthwhile modification for drivers who prioritize handling and track-like performance. The benefits in stability, reduced body roll, and improved cornering are significant, especially when paired with other suspension upgrades. However, it s not a universal fix it may sacrifice some ride comfort and could exacerbate issues if not properly integrated with the rest of the suspension.

If you re looking to **enhance the car s driving dynamics** without overhauling the entire suspension, this is a cost-effective and relatively straightforward upgrade. For **daily commuting or comfort-focused driving**, the trade-offs in ride quality may not be worth it unless you re also making other suspension changes.

---

- You enjoy spirited driving or track use.

- You ve already made other suspension modifications (e.g., lower springs, stiffer shocks).

- You re willing to accept a slightly firmer ride in exchange for better handling.

- You choose high-quality mounts (e.g., from **BC Racing, Eibach, or Ohlins**) that are designed specifically for the E30.

- You primarily drive on rough or poorly maintained roads.

- You haven t addressed other suspension components (e.g., shocks, bushings).

- You re on a tight budget and can t justify the minor ride quality trade-off.

- You re unsure about installation consider having a trusted mechanic verify fitment.

**Final Verdict:** For the right driver, this is a **solid mid-range suspension upgrade** that offers noticeable improvements without requiring a full rebuild. Pair it with proper maintenance (e.g., checking bushings, alignment) to maximize longevity and performance.
