The AST Lowering Springs for BMW 4 418i (03/2014-07/2021) represent a high-quality solution designed to enhance your vehicle's driving dynamics by lowering its center of gravity. Manufactured with precision using cold-coiling technology on the finest Wafios coiling machines, these springs ensure durability and consistent performance. Their engineered progressive design provides a balanced reduction in ride height—30 mm at the front and 30 mm at the rear—without compromising the comfort levels associated with the original equipment manufacturer (OEM) springs.

Crafted specifically for the BMW 4 418i model, these springs serve as a direct replacement for the OEM components, guaranteeing compatibility and ease of installation. The use of premium materials and advanced manufacturing processes contributes to the springs’ resilience and longevity, supported by a lifetime warranty against breaking. This warranty underscores the brand's commitment to quality and reliability, providing peace of mind for professional and private users alike.

The AST Lowering Springs not only improve the vehicle’s aesthetic stance by reducing the ride height but also enhance handling characteristics by lowering the center of gravity. This results in improved cornering stability and reduced body roll, which are critical factors for both everyday driving and more spirited performance scenarios. Despite the lowered stance, the springs maintain a ride quality close to the OEM standard, ensuring that comfort is not sacrificed for performance.

It is important to note that these springs are not suitable for four-wheel-drive (4WD) vehicles. Additionally, vehicles equipped with M-Sport or Adaptive M-Sport suspension systems will experience approximately 10 mm less lowering than the specified values. This consideration ensures that users select the appropriate suspension components tailored to their vehicle’s configuration.

Lowering Specifications

  • Front lowering: 30 mm
  • Rear lowering: 30 mm
  • Approximately 10 mm less lowering for M-Sport suspension variants
  • Approximately 10 mm less lowering for Adaptive M-Sport suspension variants

Compatibility

  • Designed specifically for BMW 4 418i models manufactured between 03/2014 and 07/2021
  • Direct OEM spring replacement
  • Not compatible with four-wheel-drive (4WD) vehicles
  • Suitable for vehicles with standard suspension setups

In summary, the AST Lowering Springs provide a reliable, high-performance upgrade for BMW 4 418i owners seeking to improve handling and vehicle aesthetics while maintaining ride comfort. Their precise engineering, backed by a lifetime warranty, makes them a dependable choice for professionals and enthusiasts who demand quality and consistency in their suspension components.

It’s ok
Color: Black, Size: Queen
It’s a very nice mattress topper. Is comfy, but it’s not as fluffy as advertised. And it is not cooling.

COOL, COMFORTABLE & CUSHIONY
Color: White, Size: King
I Love, Love, Love this Mattress Protecter, Cover, Topper, it is "thick, cool, beautiful and just the right size for my bed, I purchased it "King Size" because I like it to go all around my mattress so it covers and protects "all of my mattress". It is Fluffy, just enough Padding to Support your body's weight. I had one previous to this one, it was the same brand, the same comfort and I've had it for Years, it is very Durable and Stain /Resistant. I have no complaints. I am going to try to upload a short clip, please bear with me, it's my first time posting a video and I am an amateur...I hope you love it as much as I do because you will have years of use with this "Mattress Topper".

Would recommend!
Color: White, Size: Queen
I bought this mattress topper for my teenage daughter for her bed. It was on sale when I purchased it and when it arrived I loved the quality and softness of the topper. Great buy for the price! It stays in place and fits as sized. I have yet to launder it, but I would assume it will wash up just fine. My daughter loves it and makes her bed dreamy.

Saved me so much money
Im loving this mattress topper. It has added a noticeable layer of comfort to my firm mattress without making it feel too soft. The cushion is plush yet supportive and has made sleeping more comfortable overall. The bamboo feels soft and breathable. It fits on the mattress with the deep pockets and stays in place alk night. Setup was easy and it fluffed up after unpacking. If you have a firm mattress and want extra comfort without replacing it, this topper is a great option. Highly recommend

Comfortable, cooling, and OEKO-TEX certified, it’s a great way to refresh any mattress.
This 3-inch mattress topper instantly upgraded my bed with a softer, cooler, and more supportive feel. The bamboo-viscose fabric is noticeably breathable, helping regulate heat throughout the night—great for hot sleepers. The 1200GSM down-alternative fill adds plush, cloud-like cushioning while still offering balanced support for the back and shoulders. It fits securely with the deep pockets and stays in place even when turning. After allowing it to fully expand, the topper fluffs up beautifully. Comfortable, cooling, and OEKO-TEX certified, it’s a great way to refresh any mattress.
