What does the Dinan G8X M3 brace fit?

It fits the G80 BMW M3, G82 and G83 BMW M4 (2021-present), and G87 BMW M2 (2023-present), all equipped with the S58 twin-turbo inline-six. It bolts directly to the factory strut tower mounting points.

What does the Dinan G8X M3 brace do?

It ties the two front strut towers together in a single reinforced carbon fiber piece, replacing the OEM two-piece bar and reducing chassis flex under hard cornering for sharper, more predictable steering response.

Is the Dinan G8X M3 brace legal in California?

No. Dinan lists this part as not legal for sale or use on pollution-controlled vehicles registered in California, and CARB approval is still pending an Executive Order number. Confirm your local emissions rules before ordering if you're outside California.

How much weight does the Dinan G8X M3 brace save?

The carbon fiber brace weighs 2.8 lbs versus roughly 8.4 lbs for the factory two-piece steel bar, a savings of about 5.6 lbs at the front of the chassis.

Is installation difficult?

No. It's a straightforward bolt-on that reuses the factory strut tower mounting hardware, with an estimated labor time of about 15 minutes.

Does the Dinan G8X M3 brace come in other finishes?

Yes. This listing is the matte carbon fiber finish; the same brace is also available in a gloss carbon fiber finish as Dinan part number D180-0015.

Description

Dinan Matte Carbon Fiber Front Strut Tower Brace for G80 BMW M3, G82 / G83 M4, and G87 M2

Dinan G8X M3 brace replaces the factory two-piece strut bar on the G80 M3, G82 and G83 M4, and G87 M2 with a single reinforced carbon fiber piece that ties the front strut towers together. Where the stock bar flexes under hard cornering, Dinan’s design adds rigidity to the chassis for sharper, more predictable steering response, while dropping noticeable weight up front and giving the engine bay a stealthier matte finish.

Features

2×2 twill carbon fiber construction in a matte finish, with inset aluminum mounting points for strength
Weighs 2.8 lbs versus roughly 8.4 lbs for the factory two-piece steel bar, a savings of about 5.6 lbs
Bolt-on installation using the factory strut tower mounting hardware; estimated labor time is 0.25 hours
Coordinates visually with the Dinan cold air intake for a unified engine bay, though it fits with the stock intake as well
Reduces chassis flex during hard cornering for improved rigidity and steering feel
Available in gloss carbon fiber, sold separately as Dinan part number D180-0015

Every Authorized Dinan Performance Center can help build anything from a single upgrade to a complete Dinan BMW.

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.
