I can't comment on H&R or BONOSS wheel spacers. I have fitted 20mm Eibach Pro-Spacer wheel spacers to my 2016 Outlander PHEV.
Now it handles better in corners thanks to a wider track. Eibach are an established company and all their Pro-Spacers are TUV certified.
It also now looks more like the Concept-S show car Mitsubishi unveiled at the Paris Motorshow in 2014 with all four wheels pushed to the corners rather than tucked in like the production version.
Make sure you choose hub centric wheelspacers as these are safer and the recommended type over universal wheel spacers.
