Does the Dinan G80 M3 sway bar set fit the xDrive M3 or M4?

No. This set is engineered for RWD platforms only and is not compatible with the BMW M3 Competition xDrive or M4 Competition xDrive. The G87 M2 is unaffected, since it's RWD-only from the factory across all trims.

What does the rear bar's adjustability do on the Dinan G80 M3 sway bar set?

The rear bar has two mounting holes, letting you shift roll stiffness between the front and rear of the chassis. Softer settings favor a more neutral, forgiving balance, while stiffer settings sharpen rotation for spirited driving or track use.

How much stiffer is the Dinan G80 M3 sway bar set than stock?

The front bar is about 18% stiffer than the factory unit, and the rear bar ranges from 35-48% stiffer than stock depending on which adjustment hole you select, giving you a meaningful range of tuning without changing springs or dampers.

Can I install the Dinan G80 M3 sway bar set myself?

Dinan's documented labor time is 10.3 hours, and the job requires dropping the subframe to access the mounting points. Because of that, professional installation with an alignment afterward is strongly recommended rather than a driveway job.

Is the Dinan G80 M3 sway bar set legal for street use?

Yes. The set carries Emissions Code 5, meaning it's legal for street and track use in all 50 states, since it doesn't affect emissions equipment.

What's included with the Dinan G80 M3 sway bar set?

You get a front anti-roll bar, a rear anti-roll bar with adjustable end link mounting, polyurethane bushings for both bars, and the grease needed for a proper installation.

Description

Dinan Adjustable Front and Rear Sway Bar Set for G80 BMW M3, G82 / G83 M4, and G87 M2

Dinan G80 M3 sway bar set replaces the stock front and rear anti-roll bars on the G80 M3, G82/G83 M4, and G87 M2 with stiffer, purpose-built units that cut body roll and sharpen turn-in without touching ride quality on the street. The rear bar’s two-hole adjustability lets you dial in the balance between understeer and rotation to match your driving style or track conditions.

Tighter Roll Control, Tunable Balance

Every S58-powered M2, M3, and M4 leaves the factory with a stock bar setup that favors comfort over outright body control. Dinan’s front bar steps up to 28mm (an 18% increase in stiffness over stock), while the rear bar jumps to 26mm and can be set for a 35-48% stiffness increase over stock depending on the hole selected. The result is a chassis that resists roll through fast transitions and holds a flatter, more predictable line without the harshness of a full coilover swap.

Features

Direct-fit front and rear anti-roll bars engineered specifically for the G80 / G82 / G83 / G87 chassis
Rear bar offers 2-hole adjustable mounting so you can tune the roll stiffness split between front and rear
Black polyurethane bushings included, paired with the correct grease for a squeak-free install
Emissions Code 5, meaning the set is legal for street and track use across all 50 states

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.
