Perrin Performance PPS-SUS-535 Rear Differential Lockdown for Subaru STI/WRX: A Detailed Analysis

The Perrin Performance PPS-SUS-535 Rear Differential Lockdown is a popular aftermarket upgrade for Subaru STI and WRX models. This device is designed to enhance traction and stability by mechanically locking the Subaru differential during hard cornering. In this analysis, we will discuss the pros and cons of purchasing this product.

1. Improved Traction: The Perrin Performance PPS-SUS-535 Rear Differential Lockdown provides additional traction, especially during hard acceleration and cornering. It reduces wheel spin and helps in maintaining consistent power delivery to the ground.

2. Enhanced Stability: With the differential locked, the vehicle's weight is evenly distributed between the left and right wheels, resulting in improved stability. This is particularly beneficial when driving on uneven or slippery surfaces.

3. Reduced Tire Wear: By preventing the inside wheel from spinning during hard cornering, the Perrin Performance PPS-SUS-535 Rear Differential Lockdown helps to reduce tire wear.

4. Easy Installation: The Perrin Performance PPS-SUS-535 Rear Differential Lockdown can be installed relatively easily, with no major modifications required. The installation process does not involve cutting or drilling.

1. Increased Cost: The Perrin Performance PPS-SUS-535 Rear Differential Lockdown is an aftermarket upgrade that comes with an additional cost. It may not be within everyone's budget.

2. Potential Negative Impact on Drivability: While the Perrin Performance PPS-SUS-535 Rear Differential Lockdown provides numerous benefits, it may also negatively impact drivability in certain situations. For instance, it might make the vehicle less forgiving during aggressive driving, and it could potentially increase the risk of wheel hop.

3. Limitations: The Perrin Performance PPS-SUS-535 Rear Differential Lockdown is designed to work only with the factory Subaru differential and will not work with aftermarket differentials or limited-slip differentials.

The Perrin Performance PPS-SUS-535 Rear Differential Lockdown is an effective aftermarket upgrade for those looking to enhance traction, stability, and reduce tire wear in their Subaru STI or WRX. However, it comes with additional cost and potential negative impacts on drivability. Ultimately, the decision to purchase this product depends on individual preferences and driving styles. If you prioritize improved traction and stability, the Perrin Performance PPS-SUS-535 Rear Differential Lockdown is a worthwhile investment.

If you're considering purchasing the Perrin Performance PPS-SUS-535 Rear Differential Lockdown, make sure you weigh the pros and cons carefully. Consider your budget, driving style, and preferences.
