Destroy or Die Adjustable Front Upper Control Arm Specifications Made in England by Destroy or Die these adjustable upper front arms allow you to precisely adjust the camber of your Mazda MX-5 or Miata NA and NB with the integrated threaded ball joint. Designed for competitive use these suspension parts are particularly solid and offer several advantages over other modified arms available on the market. These adjustable lower arms are suitable for lowered cars by eliminating the risk of contact with the chassis allowing for an increase of wheel clearance due to their tapered shape and to optimally install all types of aftermarket suspensions thanks to the large opening for the shock absorber. No bodywork or chassis modification is necessary for these parts which are mounted in place of existing ones. Easy to install they are designed to accommodate OEM or reinforced bushes (we offer them separately under the Powerflex brand). This set includes 2 upper front arms (left and right) and 2 ball joints. Warnings: These FUCA will need to be installed using the outer ball joint positions or suitable wheel spacers when fitting 13 or 14 Wheels with an ET0 or higher offset. NB Knuckles require removing 3-4mm from the inner face of the upper ball joint mounting point to ensure proper thread engagement. Bushes are not included unless you add them in the drop down menu. Bushes will not be installed.
