How much do the BMW G8x lowering springs drop the car?

RWD G80 M3 and G82 M4 models drop 30mm front and 30mm rear. xDrive models drop 25mm front and 20mm rear. The different xDrive figure accounts for the slightly different geometry and weight distribution of the all-wheel-drive drivetrain components — using the same drop on both axles on an xDrive car would result in an uneven stance.

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

Yes. The MMX G8x lowering springs are fully compatible with both the standard fixed dampers and the Adaptive M damper system. The progressive spring rates are engineered to work within the operating range of both damper setups — no damper replacement or recalibration is required.

What is a progressive spring rate and why does it matter on the G8x?

A progressive spring starts with a softer rate at low deflection and progressively stiffens as compression increases. On the G8x, this means the spring feels compliant over road imperfections and at lower speeds where comfort matters, while delivering increased support and reduced body roll when cornering loads rise. A fixed-rate spring that is stiff enough for spirited driving tends to feel harsh in everyday use; progressive rates avoid that compromise.

Will these springs affect the M3 / M4's ride quality noticeably?

Lowering springs always involve a trade-off — a lower center of gravity and reduced body roll come with a modest increase in ride firmness compared to the factory setup. The progressive rates on the MMX BMW G8x lowering springs are designed to keep that trade-off acceptable for daily use, retaining compliance at low speeds where it matters while improving chassis composure during harder driving.

Do the springs fit both the M3 Touring (G81) as well?

No. These springs are designed for the G80 M3 saloon and G82 M4 coupe only. The G81 M3 Touring uses different spring perch geometry and is not compatible with this set.

Description

MMX Lowering Springs for G8x BMW M3 and M4 (RWD and xDrive)

BMW G8x lowering springs from MMX Performance are a complete spring set for the G80 M3 and G82 M4, engineered to reduce ride height, lower the center of gravity, and sharpen handling response while preserving the everyday drivability that makes the G8x chassis work as a road car. RWD models drop 30mm front and rear; xDrive models drop 25mm front and 20mm rear, both figures reducing wheel arch gap for a more planted, aggressive stance without the harshness of a fixed-rate sport spring. Progressive spring rates are the key to that balance: at low speeds and over urban surfaces, the spring works in its softer initial range, maintaining ride comfort; at higher speeds and lateral loads, the rate increases to reduce body roll and sharpen turn-in. The springs are fully compatible with both the standard G8x dampers and the Adaptive M damper system, no damper changes required, and are finished in MMX metallic grey for a clean OEM+ appearance.

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.
