We recently received a Facebook message from a customer asking about upgrading the seats in his BMW M140i. To provide a comprehensive answer, we’ve put together this blog post detailing the benefits of upgrading the seats, the specific subframes available, and the types of seats that work best with each subframe. If you’re looking to enhance your driving experience in a BMW M140i, read on to find out which options might suit you best.

Seat Options for Your BMW M140i

The list of seats that fit using the brackets we discuss later in this blog is extensive and almost endless. Between the three brackets we recommend, we can fit any seat into your BMW M140i. So we have shortlisted the seats here to the most popular we’ve found this year.

Our Recommended Fitting Brackets

When upgrading your seats, the right mounting brackets are crucial for ensuring a secure fit and optimal driving position. We offer three key types of subframes for the BMW M140i: Recaro, Planted Technology, and PCI Racing. As a rule of thumb we recommend using the Recaro base frame for the Recaro seats listed above (+Side mounts for the Pole Positions), the PCI Racing for all other side mounted bucket seats, and the Planted Technology if you are looking at any other reclining seats from our website not listed here. 

Recaro Subframe

The Recaro subframe is designed to be a direct fit for the BMW M140i, providing a seamless installation process. Recaro seats, known for their ergonomic design and high build quality, are a great choice for both daily driving and track use. Popular models that can be used with this subframe include the Recaro Sportster CS and Recaro Pole Position.

Planted Technology Subframe

Planted Technology subframes are renowned for their durability and precision engineering. These brackets offer a solid base for a wide range of aftermarket seats, ensuring compatibility with most brands. They are made from 3/16″ steel, providing maximum strength and safety. You can pair these with seats from various manufacturers due to the multiple bolt location pattern they provide. This includes fitment for all major brands including Sparco, Bride, Cobra, and Corbeau.

PCI Racing Subframe

PCI Racing subframes are another excellent choice for the BMW M140i, offering robust construction and compatibility with a variety of side mounted racing seats. PCI Racing is known for its high-quality products that meet the demands of competitive motorsport. This subframe works well with side-mounted racing seats from brands like OMP to Mirco. We tend to recommend this setup for pretty much every side mounted seat on the market.

Final Thoughts

So, with all these choices there are just a few final things to consider. 

  1. Fit and Comfort: Ensure the seat dimensions match your body size for optimal comfort and support. Test different models if possible to find the best fit.
  2. Weight: A lighter seat can improve your car’s performance by reducing its overall weight.
  3. Safety: Look for seats that offer good lateral support and have proper harness compatibility for track use.
  4. Material: Choose materials that suit your driving conditions and preferences, such as leather for durability or Alcantara for grip.

Upgrading the seats in your BMW M140i can transform your driving experience, offering enhanced comfort, better support, and improved aesthetics. Whether you choose Recaro, Planted Technology, or PCI Racing subframes, ensure that your new seats are properly fitted to maximize their benefits. It’s now time to explore the seat options we have in stock.
