Review TURNER PERFORMANCE PRODUCTS Blade Brake Rotor Rear

The **Turner Performance AX39-187 Blade Brake Rotor** is a high-performance, precision-engineered rear brake rotor designed to deliver exceptional stopping power, durability, and thermal management for demanding driving conditions. Crafted from a proprietary **blade-style design**, this rotor features a unique, aerodynamically optimized shape that enhances airflow and heat dissipation, reducing the risk of brake fade and thermal warping common issues in aggressive or high-load applications. The **AX39-187** is engineered with a **187mm diameter**, striking a balance between compactness and robust stopping capability, making it an ideal choice for performance-oriented vehicles, including muscle cars, hot rods, and high-performance street machines. Constructed from **high-grade cast iron**, the rotor is treated with a **heat-resistant coating** to improve resistance to warping and corrosion, ensuring consistent braking performance even under extreme thermal stress. The **blade profile** not only improves cooling but also reduces unsprung weight, contributing to better handling and responsiveness. Paired with Turner s **precision-machined surfaces**, this rotor offers superior pad contact, minimizing brake squeal and maximizing friction efficiency. Whether tackling spirited drives, track days, or heavy-duty towing, the **AX39-187 Blade Brake Rotor** combines cutting-edge engineering with rugged reliability, making it a standout upgrade for enthusiasts seeking superior braking performance without compromising on durability.

### **Pros and Cons of buying a Turner Performance AX39-187 Blade Brake Rotor (Rear)**

1. **Performance Enhancement** The AX39-187 blade rotor is designed to improve braking performance by reducing heat buildup and increasing pad contact area. This can lead to better stopping power, especially under heavy loads or in high-performance driving conditions.

2. **Durability and Heat Dissipation** The blade design helps with airflow, reducing heat retention compared to traditional solid rotors. This can extend rotor life, particularly in aggressive driving or towing scenarios.

3. **Compatibility with High-Performance Brake Pads** The rotor is engineered to work well with high-performance brake pads, such as ceramic or semi-metallic compounds, which can improve braking efficiency and reduce dust.

4. **Lightweight Construction** The blade design incorporates cutouts and slotted patterns, which reduce overall weight compared to solid rotors. This can contribute to better vehicle handling and acceleration.

5. **Aftermarket Support** Turner Performance is a reputable brand with a strong reputation in the aftermarket performance industry, offering reliable parts with good customer support.

6. **Aesthetic Appeal** The aggressive blade design adds a sporty look to the vehicle, which may be desirable for enthusiasts.

7. **Potential for Upgraded Braking in Stock or Modified Vehicles** If your vehicle s stock brakes are underpowered, this rotor can provide a noticeable upgrade without requiring a full brake overhaul.

---

1. **Cost** The AX39-187 is a premium aftermarket rotor, and the price is significantly higher than OEM rotors. This may not be justified for daily drivers with mild braking needs.

2. **Noise Potential** Blade rotors can generate more brake squeal or noise, especially when new, due to their design and the materials used. This may require brake pad adjustments or aftermarket pads to mitigate.

3. **Maintenance Requirements** The cutouts and slots in blade rotors can trap debris, which may require more frequent cleaning or inspection to prevent brake fade or reduced performance over time.

4. **Potential for Warping** While blade rotors dissipate heat better than solid rotors, they can still warp if subjected to extreme braking or overheating, particularly in heavy-duty applications.

5. **Limited Availability of OEM-Style Fitment** Unlike OEM rotors, the AX39-187 may not fit perfectly out of the box, requiring machining or shimming in some cases. This adds to labor costs if professional installation is needed.

6. **Not Ideal for All Driving Conditions** In wet or slippery conditions, the blade design may not provide as much braking consistency as a solid rotor, as water can pool in the cutouts.

7. **Potential for Overkill on Stock Vehicles** If your vehicle s braking system is already adequate for your driving habits, upgrading to this rotor may not offer meaningful benefits and could be seen as unnecessary spending.

---

The Turner Performance AX39-187 blade rotor is a high-quality aftermarket upgrade that excels in performance-oriented applications, such as track use, aggressive driving, or towing. Its design offers superior heat dissipation, durability, and braking efficiency, making it a strong choice for enthusiasts who prioritize performance over cost. However, the increased cost, potential for noise, and maintenance requirements mean it may not be the best fit for everyday drivers or those on a tight budget.

If you frequently push your vehicle s braking system, experience brake fade, or seek an aesthetic upgrade with performance benefits, this rotor is a solid investment. For casual drivers or those with stock braking needs, a more budget-friendly OEM or mid-range aftermarket rotor may suffice.

- **Buy if:** You drive aggressively, tow frequently, or participate in track days; you want improved braking performance and heat management; and you re willing to invest in a premium aftermarket part.

- **Skip if:** You primarily drive in urban or light conditions, are sensitive to noise, or prefer a more cost-effective solution.

- **Consider alternatives:** If you like the blade design but want a more budget-friendly option, explore other brands like EBC, Akebono, or StopTech. For maximum performance, pair this rotor with high-quality brake pads and calipers. Always ensure proper installation and break-in procedures to optimize performance.
