ALTA Rear Control Arms are the ultimate upgrade for your MINI, replacing your rear lateral links with a solid and performance-focused design. These control arms enhance traction and handling while giving you precise control over camber and toe settings. The flexibility of ALTA control arms allows for fine-tuning without the hassle of removing and reinstalling the linkage. Simply adjust the lock nuts and twist the center section to achieve your desired settings.

These control arms are the perfect complement to other suspension products like springs, coilovers, or sway bars.

Key Features of ALTA Rear Control Arms:

  • CNC machined from 6061 aluminum rod for durability.
  • Heavy texture powder coating for corrosion resistance and added style.
  • Teflon-lined spherical rod ends for a solid connection and improved articulation.
  • Aircraft-quality spherical bearings for smooth and precise movement.
  • Injected Nylon around the ball center for quiet operation as the part ages.

For a comprehensive rear end upgrade, consider purchasing two sets of control arms to replace both upper and lower control arms. This minimizes deflection from the OEM rubber bushings and reduces weight. Please note that on models with Xenon-style headlamps, some modifications to the leveling sensor mounting may be necessary. For additional details, consult your ALTA dealer or our Tech Department.

ALTA Rear Control Arms come with high-quality hardware, including corrosion-resistant spacers and Grade 8 adjustment nuts.

M4 CSL brace has been designed to enhance the sportive character of M cars, at the same time as it brings the best rigidity to the chassis. Designed and manufactured in Spain under strict quality requirements according to UNE-EN ISO 9001:2015. This piece is made by hand with the best carbon fiber prepreg. This piece is manufactured by combining craft and technology. On the one hand, with the care and attention to detail that characterizes our company, and on the other, with the use of the most modern equipment in some critical points of the process, such as 3D scanning, autoclave curing, and robotic cutting. The G8X CSL strut brace has been manufactured with monobloc tubular technology, avoiding unnecessary joints that could result in weak points. Lamination has been carefully designed, and we include 3 different fabrics, all best quality, including high-modulus unidirectional carbon. 6061 aluminum machined components complete the piece providing great resistance to wear in the area of joint to the chassis. Not just to save weight, but to achieve the strength and rigidity necessary for a functional part with similar characteristics to the OEM part. The result? A piece with an OEM finish and fitment, but with an awesome appearance and only 1.8 kilos, which is a significant weight reduction compared to the original bar which is 3.5 kilos.
