Overview:

Suspension systems that not only transform the stance of the vehicle but also maintain ride quality and improve upon handling are what Dinan suspensions are known for. This is accomplished by pairing springs sets with bump stops spring perches or both to maintain suspension travel resulting in a smooth ride while also improving mechanical grip and handling. This is what makes Dinan suspension systems unique. While we are able to sell each component separately, it is highly recommended that both the spring sets and the supplemental ride quality and handling kits are used in tandem in order to maintain the Dinan quality standards our customers are used to. Experience the Dinan difference with this combination and enjoy the ride it provides. Dinan's Performance Spring set for the F22 228i/230i (RWD) and F32 428i/430i (RWD) provides greater control over body roll by virtue of carefully calibrated spring rates. Additionally, Dinan lowers the vehicles by at least 1/2" (drop varies by application) for improved suspension geometry and an even more aggressive stance. The Dinan springs are CNC wound with high tensile chrome silicon wire and shot-peened for stress relief to last the life of the car. The substantial increase in stiffness will reduce the rear suspension compression under acceleration and front suspension compression (or dive) under braking, giving your car a more controlled feel. The Dinan performance springs will also provide a noticeable improvement in grip for high-speed driving situations that will inspire confidence in your car's capabilities. The reduced body roll makes the steering more responsive to driver input and will be noticed at speeds as low as 20 mph up to the top speed of the vehicle. NOTE: Dinan Performance Spring sets should be purchased and installed with the corresponding Ride Quality and Handling Kit to achieve the advertised ride height performance and ride quality. While not explicitly required, if the matching component is not purchased and installed you will get less than favorable results in the form of poor ride quality and improper handling traits. While we will maintain a full warranty on product defects any claims against the cars improper handling ride quality traits due to not purchasing the corresponding handling kit will not be warranted.

  • Vehicle lowered 1/2" in the front and rear (F22 228i/230i RWD)

Easy installation and comfortable
Color: Black, Style: Classic, Color: Black, Style: Classic
This chair features a premium, quilt-stitched design with thick cushioning that immediately feels supportive. Installation is straightforward — the major components align cleanly, and the hardware fits without forcing, allowing the entire setup to be completed quickly. Once assembled, the chair provides excellent comfort: the padded headrest, wide seat, and soft armrests create a stable, ergonomic sitting experience suitable for long work sessions. The overall build feels solid, and the smooth-rolling casters add to the ease of use.

Seat angle problem
Color: Black, Style: Classic
This chair is very good. Has exactly the dimensions I was looking for. Overall it looks very well made, excellent quality, easy to install. I'm not giving it 5 starts because I'm not liking the angle of the seat very much. It goes low at the back end and at the front it is very high. It feels really good when I'm working on my computer where I have 1 widescreen monitor with 2 smaller ones on top, so it is very comfortable there. But not so much when I'm just working on my desk filling forms and reading papers. I'm actually getting low back pain. I wrote the seller to ask if there is any kind of adjustment I can make but it doesn't look to me like there is anything than can be done. I'm still keeping it.

Most comfortable office chair this fluffy guy has ever sat in.
Color: Black, Style: Classic
This chair is incredibly comfortable—easily the most comfortable one I’ve ever sat in. At around 300lbs, I’ve struggled to find a chair that’s both supportive and spacious. Most options feel tight, with the armrests pressing into my hips. Not this one. If anything, I feel small in it—there’s plenty of room on either side. It’s like going from a cramped budget airline seat to first class on a full-service carrier. The lumbar support is the best I’ve ever used. The materials are top-notch—everything from the base to the legs to the casters is metal (feels like steel). The casters themselves use what look like inline skate wheels and glide effortlessly across carpet—almost too well on hard surfaces, so you might want to consider a rug. Not a flaw, just something to keep in mind. I’ve paid twice as much for chairs that felt half as good, so in my opinion, this is an excellent value. The faux leather looks great and the stitching appears durable. While it may not last as long as real leather or high-quality fabric, it should hold up for a reasonable amount of time. Tilt functionality is basic—just two settings: upright or slightly reclined. Honestly, that’s all I need. If you’re looking for something to nap in, this might not be the chair for you. But for office work or gaming, it absolutely delivers all-day comfort. For reference, I’m 5'8", and the headrest aligns perfectly with the back of my head. If you're 6'5", it might end up being more of a neck rest. And I have to give a special shoutout to the included T-shaped hex wrench. It may sound silly, but this alone earns it a 5-star review from me. Every other chair I’ve bought includes those awful angled hex wrenches that make you slam your knuckles into the frame with every turn—often accompanied by some colorful language. Sure, I have my own tools, but finding where my wife hid them isn't always easy. A good-quality tool in the box? That’s thoughtful and appreciated.

Wide and comfortable office chair
Color: Black, Style: Classic, Color: Black, Style: Classic
It's made of very fine leather and in good quality. It has a pump to pump air to the back of the chair, so I can adjust the softness of the chair back. It's a very wide chair. Maybe the widest one I ever bought. I can only sit half of its space. It's very easy to install, the alignments are perfect. Its arm and height is adjustable. The wheels are advance ones which make it move through the floor smoothly. It looks an advance chair if you want an upgraded experience.

Comfortable Seating
Color: Black, Style: Classic
I honestly didn’t expect this chair to be this comfortable, but it has exceeded my expectations in every way. I sit at my desk for long hours every day, and the adjustable air-pump lumbar support has been a total game changer. I love that I can fine-tune the firmness depending on how my back feels that day. My lower back pain has noticeably improved since switching to this chair.The seat is wide, thick, and very supportive without feeling stiff, which makes long work sessions much more comfortable. The armrests are another big plus—they adjust in so many directions that I can always find the perfect position for typing, reading, or relaxing. The chair feels extremely sturdy and well built, and it gives me confidence knowing it supports higher weight without wobbling.Assembly was straightforward and took about 20 minutes. Overall, this chair feels premium, comfortable, and thoughtfully designed. I would absolutely recommend it to anyone looking for a reliable, all-day office chair.
