Out with the old in with the new!
Installed these @ 90,000 miles on my 2016 WRX STI.
Old ones were toast! You can definitely tell the difference
At high speed cornering, and the body roll in the front with the thicker bushings. Superpro supplies more than enough grease for you to get the job done with both! These bushings are for the STOCK 24mm front sway bar btw! Installation is easy once you remove the protective under tray on the STI model. Highly recommended for stock replacement and to really living up the fresh off the lot feeling again!
