I have over 14,000 miles on mine. Probably few cone impacts too. One came loose. I cleaned surface to remove any wax /grease prior to installation. VHB takes times to setup. I drove the car in winter.. with SNOW packed up on them.
One of my first mods.. well.. only mods
Rears I did modify install direction and use longer spacers since ones provided seemed way to fkn short. Trip to HD and handful of nylon spacers.. DONE.
