Just installed my f & r sway bars. Front bar is 21mm & the rear is 3-way adjustable 20/22/24mm. I set mine at 22mm. I purchased the kit which came with everything(f & R end links,brackets,mounts,bushings & grease). The directions are great all step by step B & W pictures. Installation for the rear is simple(about an hour). The front is easy but time consuming(about 2 hours). Quality and workmanship is A1. The rear end links and bushings have grease fittings and are high polished aluminum. The bars are powder coated red. The front end links are adjustable in hight. Now I already had installed the Prodrive sport springs and STI replica strut bars. This was the perfect balance I needed to complete my suspension mods. I should of installed these sooner. There is a huge improvement in cornering. By the way I'm still running stock tires so those of you that already have improved in that area you will be even more amazed. I can't say enough about them. Except for my Prodrive stage 2 kit this is the most noticeable mod. The bars give you a VERY stable and predictable feeling coming in and out of a corner. Two thumbs up for Hotchkis and thanks to Mike @Subaruxtras.com for the recomendation.
