Ideal for enthusiasts who have already upgraded their suspension or are looking to fine-tune their 944 s handling, this component seamlessly integrates with the existing system, offering a straightforward yet impactful modification. With its OEM-inspired design and robust construction, the **477511413** is a must-have for anyone serious about maximizing the performance potential of their classic Porsche 944.

### **Pros and Cons of Buying a Porsche 944 (951 Turbo S2) with a Modified Rear Anti-Roll Bar (18mm End Links)**

#### **Pros**

1. **Enhanced Handling and Stability**

The stock rear anti-roll bar (ARB) on a 944 is relatively soft, which can lead to excessive body roll during aggressive cornering. Upgrading to an 18mm end-link setup (often paired with a stiffer ARB or aftermarket links) reduces body roll, improving stability and precision in corners. This is particularly noticeable on twisty roads or when pushing the car harder.

2. **Better Weight Distribution**

The rear end of a 944 is naturally light, and a stiffer ARB helps counteract understeer tendencies, especially when carrying extra weight (e.g., aftermarket wheels, exhaust, or a tuned engine). This can make the car feel more balanced and predictable.

3. **Compatibility with Other Modifications**

If you ve already invested in other performance upgrades (e.g., a turbo kit, ECU tune, or lowered suspension), a stiffer rear ARB complements these changes by reinforcing the handling gains. It s a relatively low-cost way to fine-tune the car s dynamics.

4. **Easy to Install and Reverse**

Unlike full suspension swaps or major drivetrain modifications, replacing or upgrading the rear ARB end links is a straightforward bolt-on job. Most mechanics or enthusiasts can do it in under an hour. If the setup doesn t suit your driving style, reverting to stock is simple.

5. **Cost-Effective Performance Upgrade**

Compared to more expensive modifications (e.g., a new exhaust, intercooler, or suspension kit), upgrading the rear ARB is a budget-friendly way to noticeably improve handling. A set of aftermarket end links or a stiffer ARB typically costs between **$100 $300**, depending on quality and source.

6. **Potential for Tuning Synergy**

If the car is tuned for more power, a stiffer rear ARB can help manage the increased torque and weight transfer, reducing the risk of rear-end lift or oversteer. This is especially useful for turbocharged or supercharged 944s where power delivery is more aggressive.

7. **Aesthetic and Customization Appeal**

For enthusiasts who enjoy modifying their cars, upgrading the ARB is a subtle but meaningful customization. It signals a commitment to performance tuning without drastically altering the car s appearance.

#### **Cons**

1. **Potential Over-Steer Risk**

While reducing body roll can improve stability, an overly stiff rear ARB can make the car more prone to **oversteer** (rear-wheel slide) in aggressive driving situations. The 944 is already a rear-wheel-drive car with a naturally light rear end, and excessive stiffness can make it feel less forgiving on tight or uneven surfaces.

2. **Harder Ride Quality**

A stiffer ARB reduces body roll but can make the car feel **harsher** on rough roads or when driving over speed bumps. If you frequently commute on poor pavement, the ride may become less comfortable compared to stock.

3. **Limited Real-World Handling Benefits**

The 944 s suspension is already quite simple, and the gains from a stiffer rear ARB may be **marginal** unless you re actively pushing the car in a track or drift setting. For daily driving, the difference might not be as noticeable as with more substantial modifications (e.g., coilovers or a full suspension rebuild).

4. **Compatibility Issues with Other Mods**

If the car has **lowered suspension** (e.g., from coilovers or spacers), a stiffer rear ARB might cause **binding** or premature wear on the bushings or links. This can lead to rattles or reduced longevity if not properly aligned.

5. **Quality and Fitment Variability**

Not all aftermarket ARB end links or stiffer bars are created equal. **Cheap or poorly fitted parts** can lead to premature failure, misalignment, or even damage to the suspension components. It s crucial to source high-quality parts (e.g., from reputable manufacturers like **Porsche Performance Parts, Eibach, or H&R**) and ensure proper installation.

6. **Potential for Underside Damage**

If the car is driven aggressively on rough terrain (e.g., gravel, dirt, or potholes), the rear ARB or end links can be **more susceptible to damage** due to increased stress. This is less of an issue for street use but worth considering for off-road or track applications.

7. **Minimal Impact on Straight-Line Performance**

Unlike modifications that directly affect power (e.g., turbo upgrades, exhausts, or ECU tunes), a stiffer rear ARB does **little to improve acceleration or top speed**. Its benefits are primarily in **cornering and stability**, not raw speed.

---

### **Conclusion**

Upgrading the rear anti-roll bar on a **Porsche 944 Turbo S2 (951)** with **18mm end links or a stiffer bar** is a **low-risk, moderate-reward modification** that can meaningfully improve handling for enthusiasts who enjoy aggressive driving. It s particularly useful if the car is already tuned for more power or if you ve made other suspension-related changes (e.g., lowering or coilovers).

However, the benefits are **most noticeable in track or drift settings** rather than daily driving. For street use, the gains may be subtle, and the trade-off in ride comfort could be a drawback. If you re not actively pushing the car, the stock ARB might suffice, and the extra cost may not be justified.

### **Recommendation**

- **If you re a track or drift enthusiast** or have already invested in other performance mods (turbo, tune, lowered suspension), **proceed with a high-quality stiffer rear ARB or 18mm end links**. Pair it with a **properly tuned suspension setup** (e.g., Eibach springs, adjustable shocks) to maximize benefits.

- **If you primarily drive on the street**, weigh the handling gains against the **harsher ride** and **potential oversteer risk**. Consider testing a **temporary setup** (e.g., borrowing a friend s modified ARB) before committing to a permanent change.

- **Always source parts from reputable manufacturers** (avoid no-name brands) and ensure **proper installation** to prevent binding or premature wear.

- **Monitor the car s behavior** after installation. If it feels too twitchy or unstable, consider reverting to stock or adjusting the setup further (e.g., adding a **slightly softer bar** or **adjustable end links**).

**Final Verdict:** A stiffer rear ARB is a **worthwhile upgrade for performance-focused 944 owners**, but it s not a "must-have" for casual drivers. If you re serious about tuning the car, it s a **smart, cost-effective addition** to your build. If not, the stock setup may be adequate.
