How are the BMW G8x height adjustable springs different from the standard G8x lowering springs?

The standard G8x lowering springs set a fixed drop — 30mm front and rear on RWD, 25mm front and 20mm rear on xDrive. The BMW G8x height adjustable springs use threaded perches that let you dial in exactly how much drop you want within the 20-45mm front and 10-35mm rear range, adjustable after installation. This gives coilover-like stance control while keeping the factory Adaptive M dampers rather than replacing them.

Why don't these BMW G8x height adjustable springs fit the RWD M3 and M4?

The xDrive variants use a different rear subframe and suspension geometry to accommodate the front differential and driveshaft layout, which changes the spring perch configuration at the rear. The BMW G8x height adjustable springs are engineered around the xDrive geometry and are not compatible with the RWD rear suspension layout.

Are these BMW G8x height adjustable springs compatible with the Adaptive M damper?

Yes. The BMW G8x height adjustable springs are specifically engineered to complement the factory Adaptive M damper system, preserving its characteristics rather than replacing it. The progressive spring rates are calibrated to work within the damper's operating range across its full adjustment modes.

How do I set the ride height after installing?

The threaded perches on the BMW G8x height adjustable springs allow ride height to be adjusted by rotating the perch up or down on the spring body. Set the front and rear independently to achieve the desired stance, then confirm clearance at full lock before driving. An alignment check is recommended after any adjustment.

Are progressive springs the right choice for a car with Adaptive M dampers?

Yes. Progressive spring rates start softer at low compression and stiffen progressively under load, which works well with the Adaptive M damper's variable rate settings. The BMW G8x height adjustable springs are calibrated specifically for the G8x chassis to complement those damper characteristics, delivering everyday ride comfort alongside improved chassis response when driven hard.

MMX Height-Adjustable Lowering Springs for G8x BMW M2, M3, and M4

BMW G8x height-adjustable springs from MMX Performance offer the flexibility of a coilover system while retaining the comfort and sophistication of the factory Adaptive M dampers, covering the G87 M2, G80 M3 Competition xDrive, and G82 M4 Competition xDrive. Threaded perches allow precise front-and-rear ride height adjustment across a generous range of 20mm to 45mm of drop at the front and 10mm to 35mm at the rear, giving owners the freedom to dial in their exact target stance without committing to a single fixed drop or investing in a full coilover conversion. Progressive-rate sport springs, finished in MMR Metallic Gunmetal Grey, are carefully calibrated to complement OEM damper characteristics, enhancing chassis response, turn-in sharpness, and dynamic handling without sacrificing the everyday ride quality the Adaptive M damper system delivers. The BMW G8x height-adjustable springs are the ideal solution for drivers who want adjustable aesthetics and a meaningful performance improvement with the refinement of the factory damper system preserved, rather than replacing it. Sold as a complete set of front and rear adjustable springs with threaded perches.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
