I know it's been mentioned before but it is worth getting new links when installing the 19mm rear sway bar. I got away with using the originals on my Gray 2011 (it had less than 30k on the clock). But I just got around to installing a 19mm bar on my Green 2011 with 40k+ miles. The 5mm hex socket in the end of the stud on one of the links rounded out while removing the 14mm nut holding the bar, thus rendering the link useless for installation of the new bar. I cleaned off the stud and heated the nut to release the Loctite but a couple years of road grime/water/salt had corroded the internal hex to the point of not allowing much torque prior to rounding out. It is worth purchasing a new set of links with the 19mm bar so there is not waiting (as I am doing) for UPS to deliver a set of new links.
