Does the Subaru BRZ have a limited slip differential?

Yes, the Subaru BRZ comes equipped with a limited-slip differential (LSD) as standard equipment. The LSD helps improve the car's traction and handling performance, particularly when driving on twisty roads or in slippery conditions.

What is a Limited Slip Differential?

A limited-slip differential (LSD) is a type of differential gear system that allows the driven wheels to spin at different speeds, but with a limited amount of slip between them. This is in contrast to an open differential, which allows the wheels to spin freely and independently of each other.

The LSD in the Subaru BRZ helps to distribute power more evenly between the rear wheels, reducing wheel spin and improving traction. This is particularly useful when accelerating out of corners or when one wheel has less grip than the other, such as on a slippery surface.

Benefits of the Subaru BRZ's Limited Slip Differential

• Improved Traction: The LSD helps the BRZ maintain traction and grip, especially in slippery conditions or when accelerating out of corners.


• Better Handling: The LSD allows the BRZ to turn more precisely and with less understeer, making it more responsive and agile on the road.


• Enhanced Performance: The LSD helps the BRZ's rear-wheel-drive layout deliver more power to the ground, resulting in faster acceleration and better overall performance.

The Subaru BRZ's limited-slip differential is an important feature that contributes to the car's engaging and dynamic driving experience. By helping to distribute power more effectively between the rear wheels, the LSD enhances the BRZ's handling, traction, and overall performance.

How do I tell if my differential is limited slip?

You can tell if your differential is a limited slip by performing a simple test on a lifted vehicle or by checking for a specific tag on the differential housing. With the rear wheels off the ground and the vehicle in neutral, spin one wheel by hand; if the other wheel spins in the same direction, it's a limited slip. If the other wheel spins in the opposite direction, it's an open differential. 
Method 1: Test the wheels

1. Park and secure the vehicle. Park on a level surface, engage the parking brake, and block the front wheels to prevent rolling. 
2. Safely lift the rear. Use a jack to lift the rear of the vehicle and secure it with jack stands. 
3. Place the transmission in neutral. Make sure the transmission is in neutral. 
4. Spin one rear wheel. Rotate one of the rear wheels by hand. 
5. Observe the other wheel. 
   • Same direction: If the opposite rear wheel turns in the same direction as the one you're spinning, you have a limited slip differential. 
   • Opposite direction: If the opposite rear wheel turns in the opposite direction, you have an open differential.

Method 2: Check the tag

1. Locate the differential. Find the differential housing at the rear of the vehicle. 
2. Look for a tag. Check for a sticker or tag on the differential that says, "Use only limited slip differential fluid". 
3. Consider the tag's reliability. This tag can sometimes be missing, damaged, or removed, so the wheel test is a more definitive method.

What year to avoid BRZ?

The Subaru BRZ years to avoid are 2013 and early 2014 due to significant engine issues like valve spring recall problems and potential oil consumption. While there were other recalls and issues in later years (such as a 2018 fuel pump recall), the 2013-early 2014 models are the ones most commonly cited as years to be particularly wary of.

Years to generally avoid

• 2013 and early 2014: These model years had recalls and reports of significant problems, including:
  • Valve spring recall: An issue where valve springs could fracture, leading to engine failure.
  • Oil issues: Some models, particularly those produced before a certain date, had a tendency for oiling problems.
  • Engine tuning and ECU calibration: Early models had a less optimal engine calibration.
  • Other issues: Users report issues with power windows freezing, water leaks, and interior rattles. 

Other years to be cautious of

• 2018: This year had a fuel pump recall and a recall for the rearview camera not displaying properly.
• 2019: Some 2019 models were included in the 2018 fuel pump recall. 

What to do if buying a used BRZ

• Check for recalls: Before purchasing, use the VIN to check if any recalls have been performed. 
• Be prepared for oil consumption: The BRZ can burn oil, so check the oil level regularly regardless of the model year. 
• Consider newer models: Later model years, such as the 2017 and later, generally have fewer reported issues.
