BMW M5 SQ-B Rear DiffuserThe SooQoo SQ B carbon fibre rear diffuser for the BMW G90 & G99 M5 is a very aggressive 5 piece diffuser designed to give the M5 a more muscular look from the rear. This diffuser features a central section a nice departure from the OEM diffuser which is made up of two side components with a gap in the middle. This SQ B diffuser is more traditional in design and is the perfect solution if you're not a fan of BMW's OEM styling. The high gloss finish

Avoid These Shoes
Size: 10, Color: Grey
The pair I received (gray) was not represented well in their photos. Mine had a lime green logo which looks silly. They also bunch up very badly when you pull the laces which looks ridiculous. Cheap feeling and look bad when tied. Sending back

Great pair of shoes
Size: 10, Color: Burgundy
I was a bit concerned that these shoes would be a bit large because I normally wear a size 9 1/2 and these are a size 10. But they fit perfectly. They are very light and comfortable. 👍

Great walking shoes
Size: 11, Color: All Black
A very comfortable walking shoe that’s well made and looks like it’s going to hold up well for everyday wear. Lightweight indeed and probably doesn’t require much cleaning. Easy to get on and off without much stress though.
