i dont have a 2011 WRX, but my 2008 2.5i had a crack too so i bought a lip and did the garage door DIY lip on it as well. crack has not gotten any worse my car is lowered and i scrape alot no new crack either! hahaha i guess we just have to bite it, i'm damn sure i will crack it again this winter and when i do ill just zip tie it!! i feel like if i dont want my bumper to crack: first i shouldnt have a lowered car, second i should leave it in the garage! hahah Oh well i know it sux to have a crack on a brand new car but **** happens..
theres nothing we can do about it!
