Dinan BMW Strut Braces & Stress Bars

BMWs need some added chassis strengthening in the front. You may notice some "chassis flex" when cornering or driving over a bumpy road. The reason for this is the incredible amount of force being applied to front strut towers. They have a tendency to flex when force is applied to them. Tying the strut towers together with a brace reduces the amount of flex and soldifies your car's chassis. Easy installation.

The Dinan G8x Strut Tower Brace provides additional rigidity and sharper handling to the chassis by reducing flex under hard cornering conditions. With more control, spirited driving becomes easier and infinitely more enjoyable. The lightweight brace is designed with maximum function in mind and includes linking structural elements that completely change the OEM 2-piece strut bar set into one blended system that offers additional strengthening against flex. Not one to take a back seat to functionality, aesthetics are also elevated beyond simple steel bars into striking carbon fiber (matte or gloss) with accents that tie in effortlessly into the highly geometric and angular factory engine bay for an OEM+ feel. The imposing carbon fiber brace can be installed in a matter of minutes and used in conjunction with either the stock or Dinan intake systems. While the brace was designed to specifically tie into the latter for a harmoniously balanced and unified appearance the brace can also stand on its own and elicit nearly as equally an impressive visual. Features: Improved chassis rigidity Decreased flex during cornering Lightweight: 5.6 lbs lighter than stock (Dinan CF: 2.8 lbs vs OEM Steel: 8.4 lbs) 2x2 twill carbon fiber with inset aluminum mounting points for increased strength and improved visual appeal Multiple finish options: Available in Gloss or Matte Twill Carbon (Matte Twill shown) Designed to mesh seamlessly with the Dinan cold air intake creating an aesthetically unified engine bay Bolt-on installation using factory mounting hardware

These carbon fiber strut brace bars replace the stock E63 aluminum bars. The carbon fiber tube of the Dinan bar is stiffer than the mass-produced stamped aluminum factory bar. This will reduce chassis flex in the front end and improve steering response. The carbon fiber is beautifully finished in a durable clearcoat with anodized aluminum ends. These bars frame the engine compartment in carbon fiber and go great with other carbon fiber trim.

Going beyond its Foundation counterpart, the Dinan Experience packages address not only the engine but also the chassis for a complete solution in the form of a wholly tuned Dinan vehicle. While adding power modifiers is often the go to path when beginning the modification journey, it does not fully consider what makes the car infinitely more enjoyable in scenarios outside of WOT pulls. With the addition of suspension upgrades integrated alongside the power adders the vehicle is transformed into something more than just the sum of its parts. It's a comprehensive answer to delivering additional technical capabilities in the form of increased engine performance and better handling along with improvements to aesthetics (looks and sound) in a package designed with reliability and safety in mind. This union of power and handling modifications results in a true OEM+ experience - the Dinan Experience.
