The SPL BMW G2X Front Lower Control Arms (FLCA) provide roll center, camber, and track width adjustment for the G2X BMWs (M340i, M440i, etc) while eliminating bushing deflection resulting in sharpened steering response and driving precision. The ability to run more negative camber and a slightly wider track width greatly improves the peak lateral grip available. This is especially important with better tires and a must-have for anyone looking to prevent excessive outer shoulder wear (and heating) on their tires due to a lack of camber. The lower control arms come with a ride height sensor bracket to maintain factory ride height sensor location, regardless of length of the arm to keep those finicky BMW chassis electronics happy. Suitable for all uses, from daily driver to race car. Benefits Adjustable Camber, Roll Center, and Track Width Eliminates Bushing Deflection Improved Tire Life with Ideal Camber Settings Lightweight, High-Strength Construction Stackable 304SS Roll Center Spacers in 1/8" and 1/4" Sizes US Made, PTFE Lined FK Rod Ends Materials 6061-T6 aluminum black anodized arm, clamps, and spacers 4130 CrMo electroless nickel plated double adjuster Ti6Al4V titanium socket head cap screws 304 stainless steel roll center and knuckle spacer 5/8" 4140 CrMo stud FK PTFE-lined spherical bearings (F1 spec, self-cleaning)

SPL Bumpsteer Adjustable Tie Rod Ends - BMW G8X G2X G42

SPL Tie Rod Ends for the BMW G8X, G2X, and G42 allow for bumpsteer adjustment by allowing the tie rod end pivot to be relocated with the use of spacers. On lowered cars, this results in less dynamic toe change (aka bumpsteer) as the suspension compresses (bump) during cornering and over rough roads, resulting in more predictable handling, less tire shoulder wear, and better stability over rough roads and track curbing.

Benefits

Bumpsteer Correction

Lightweight: 1.49 lbs (0.68 kg) per Side (3% Lighter than OEM)

Improves Steering Feel, Handling, and Stability Over Bumps, Especially While Braking/Turning

Reduced Front Tire Toe Wear on Lowered Cars

Improved Geometry to Maximize Articulation and Droop Travel

Maintenance-Free, US Made, PTFE-Lined FK Bearings

Materials

At Active Autowerke, it's not ONLY about making as much power as possible but to maximize the enjoyment of the drive. For 40 years, power has been the end result of improved performance due to our relentless desire to develop a refined, quality product. This philosophy behind our performance parts is best represented by one of the newest additions to our G2X/G3X BMW M340i and M440i collection. The Active Autowerke M340i/M440i rear exhaust was carefully engineered to eliminate the overly quiet sound of the factory M340i and M440i exhaust, while also allowing for optimum flow and resonance by reusing the actuator from the BMW valve. Every effort was made in addressing the not so appeasing sound of the stock OEM exhaust, but in designing an exhaust worthy for the BMW 'M' badge. We believe our rear exhaust offers the best combination of sound and performance versus other systems on the market today. Available for both models, this axle-back exhaust gives your BMW the deep, throaty, growl a car of its caliber should have had from the factory! Features: Made in the USA 304 Stainless Steel Low, Deep Sound with stock Valve Control Each exhaust test-fit on the M340i/M440i Exhaust Fixture Guaranteed to fit all G-series M340i and M440i Includes all necessary installation hardware

Awaken the B58: Active Autowerke G20 M340i / G22 M440i Valved Axle-Back Exhaust From the factory, the G-series M340i and M440i are notoriously quiet, leaving the sonorous B58 inline-six feeling a bit muffled.
