Review TURNER PERFORMANCE PRODUCTS Sport Series Brake Rotor Rear

The **Turner Performance AX-S1-2091 Sport Brake Rotor (Rear, RS917RD)** is a high-performance, precision-engineered braking component designed to deliver exceptional stopping power, durability, and thermal management for demanding driving conditions. Built to meet the rigorous demands of modern high-performance vehicles, this rotor features a **cross-drilled and slotted design**, which enhances heat dissipation by reducing hot spots and improving airflow through the friction surface. The cross-drilled holes break up brake fluid and debris, ensuring consistent braking performance while minimizing brake fade under heavy loads or repeated hard stops. Meanwhile, the strategically placed slots further enhance cooling and reduce the risk of warping, making this rotor ideal for aggressive drivers, track use, or vehicles equipped with high-performance brake systems.

Constructed from **high-quality cast iron**, the AX-S1-2091 rotor is engineered to withstand extreme temperatures and mechanical stress, providing long-lasting reliability even under the most intense braking scenarios. The rotor s **209.1mm (8.23-inch) diameter** strikes an optimal balance between compactness and braking efficiency, making it a perfect fit for rear-wheel-drive applications while maintaining a sporty, performance-oriented aesthetic. The **RS917RD** designation indicates a refined, high-performance variant, likely featuring subtle design enhancements such as optimized venting, precise machining tolerances, and a polished finish for both functionality and visual appeal. Whether paired with a high-performance brake caliper, upgraded brake pads, or a full brake system upgrade, this rotor ensures a responsive, engaging, and reliable braking experience ideal for enthusiasts seeking to push their vehicle s limits without compromising on safety or performance.

For drivers who demand precision and power, the Turner Performance AX-S1-2091 Sport Brake Rotor delivers a blend of cutting-edge engineering and meticulous craftsmanship, ensuring that every stop is as controlled and confident as the drive itself. Its compatibility with a wide range of high-performance brake setups from stock upgrades to full aftermarket systems makes it a versatile choice for those looking to elevate their vehicle s braking performance while maintaining durability and aesthetic appeal.

**Pros and Cons of buying a Turner Performance AX-S1-2091 Sport Brake Rotor (Rear, RS917RD)**

1. **Performance Enhancement:** This rotor is designed for high-performance applications, offering improved braking performance compared to stock components. The RS917RD series is known for its durability and heat dissipation, which can be critical for aggressive driving or track use.

2. **Durability:** Turner Performance rotors are built with high-quality materials and precision engineering, which contributes to their longevity. The AX-S1 series is particularly robust, making it suitable for demanding conditions.

3. **Heat Resistance:** The rotor is designed to handle high temperatures, reducing the risk of fade during intense braking sessions. This is especially useful for enthusiasts who push their vehicles hard or participate in racing.

4. **Compatibility:** The RS917RD is engineered to fit specific applications, ensuring a proper fit and optimal performance. Turner Performance provides detailed specifications to help users confirm compatibility with their vehicle.

5. **Aftermarket Support:** Turner Performance is a reputable brand with a strong reputation in the aftermarket community. This means you ll likely find reliable installation guides, customer support, and a network of professionals who can assist with installation or troubleshooting.

1. **Cost:** High-performance rotors like the AX-S1 series are significantly more expensive than stock or basic aftermarket rotors. The price reflects the advanced materials and engineering, but it may not be justified for everyday driving without aggressive braking demands.

2. **Installation Complexity:** Upgrading to performance rotors often requires replacing brake pads, calipers, and possibly brake lines. This can add to the overall cost and may require professional installation, which incurs additional labor fees.

3. **Maintenance Requirements:** Performance rotors and pads may wear out faster than stock components, especially if the vehicle is used for track days or hard driving. This could lead to more frequent maintenance and replacement costs over time.

4. **Noise:** Some high-performance rotors can produce more noise during braking, particularly if the pads or rotors are not properly bedded in. This may be a minor inconvenience but could be noticeable to sensitive drivers.

5. **Potential for Overkill:** If the vehicle is not frequently pushed to its limits, the performance gains from this rotor may not be noticeable or justified. For casual drivers, the cost may not be worth the marginal improvements.

6. **Weight:** Performance rotors are often heavier than stock rotors, which could slightly reduce acceleration or handling responsiveness in some cases. However, the impact is usually minimal compared to the braking benefits.

7. **Compatibility Risks:** While Turner Performance rotors are well-engineered, there is always a risk of misfit or improper installation if the vehicle s specifications are not double-checked. Incorrect sizing or mounting can lead to safety issues or premature wear.

The Turner Performance AX-S1-2091 Sport Brake Rotor (Rear, RS917RD) is an excellent choice for enthusiasts who prioritize high-performance braking, durability, and heat resistance. It is particularly well-suited for vehicles used in track days, autocross, or aggressive driving scenarios where stock brakes are insufficient. The rotor s advanced features justify its higher cost for those who demand the best in braking performance and reliability.

However, for casual drivers or those on a tight budget, the investment may not be necessary. The upfront and long-term costs, including maintenance and potential installation expenses, should be carefully considered against the expected benefits. If you are certain that your driving habits or vehicle use will fully utilize the rotor s capabilities, this upgrade is a strong recommendation.

- You participate in track events, autocross, or drive aggressively.

- Your vehicle s stock brakes are inadequate for your demands.

- You are prepared for the higher upfront cost and potential maintenance requirements.

- You value the brand s reputation for quality and performance.

- Your driving is primarily casual or commuter-oriented.

- You are unwilling to invest in complementary upgrades (e.g., pads, calipers, or brake fluid).

- You are concerned about the additional weight or noise associated with high-performance rotors.

- Your budget cannot accommodate the cost of installation and potential future maintenance.
