Nearly every car manufactured in the modern era carries a dark secret – fully-adjustable suspension has been all but eliminated in the name of cost-cutting and assembly-line efficiency. What this means for you is increased tire wear and more frequent replacement, as a “full alignment” consists only of rudimentary toe-angle adjustment. For over forty years, K-MAC has been hard at work developing a solution to this problem with patented innovations in camber/caster plates and bushing kits, allowing easy adjustment and a true “full four-wheel alignment” to be performed by any competent shop. These bushings make camber adjustments possible for the first time, and improve the ability to complete toe angle adjustments. When used in conjunction with the K-MAC Camber and Toe kit and Rear Adjustable Trailing Arms allows full adjustability of the 5 multi-link rear arms and positive location. Bolt-on installation – insertion/extraction tube included! Easily adjusted on the car with basic hand tools Unique failsafe locking hardware – set & forget! High quality elastomer compound resists binding Hardened & nickel-chrome plated centers for maximum bushing life 2x the load area of stock bushings Spiral grease grooves

Enhance your BMW’s performance and style with this unbeatable combo! The Turner Motorsport Carbon Fiber Strut Brace and Engine Cover are the ultimate pair to upgrade chassis stability and engine bay aesthetics—all with a single purchase.

G20/G42 Carbon Fiber Strut Brace

For G20 and G42 BMW models equipped with the B48 or B58 engines, the driving thrill is undeniable. Yet, these cars lack a crucial component found in high-performance M models: structural chassis bracing. With Turner Motorsport’s 3-point Carbon Fiber Strut Brace, you’re adding the missing link to your BMW, mirroring the handling stability of an M3 or M4. This is the only strut brace that elevates G20/G42 handling by emulating the stiffness of an M-series chassis, giving you a dynamic edge on both road and track.

The strut brace fits seamlessly into your BMW using the original factory hardware and an included stud kit, offering a hassle-free, direct installation with no modifications required. Designed and tested in-house by Turner Motorsport, this brace reduces chassis flex, enhancing control during spirited driving and providing a tighter, more responsive feel. Constructed from high-strength carbon fiber with billet aluminum end brackets, this strut brace boosts performance while adding an eye-catching focal point to your engine bay.

Strut Brace Features:

Enhanced Chassis Rigidity: Reduces flex by linking the strut towers, promoting a more precise steering response.

Easy Installation: Fits perfectly with stock mounting points using supplied hardware, ensuring a hassle-free setup. Carbon Fiber: Performance & Style

Turner’s strut brace uses structural carbon fiber, designed to endure the rigors of aggressive driving without compromising aesthetics. The brace's distinct, gloss-finished carbon fiber weave adds a sophisticated, high-performance look akin to exotic supercars. Engineered for precision, this brace effectively distributes cornering forces between the strut towers, minimizing chassis distortion and maintaining optimal wheel alignment, even in hard turns.

Turner Motorsport G-Chassis Carbon Fiber Engine Cover for B58 Engines

Give your G-Chassis BMW’s engine bay a polished, refined look with Turner’s Carbon Fiber Engine Cover. This direct replacement cover is crafted from hand-laid, gloss-finished carbon fiber, delivering a resilient, UV-protected finish. With an OE-style indentation for the BMW badge, this cover complements your engine bay with a sleek, factory look that stands out.

Engine Cover Highlights:

Direct Fitment: Seamlessly replaces the stock cover, utilizing factory mounting grommets and hardware. Durable Gloss Finish: Ensures long-lasting shine and UV protection. Distinctive Style: A premium upgrade that elevates the aesthetic of your B58 engine. Installation Notes:
