so i had to order some parts from subarupartsforyou.com and while i was added i decided to grab one of those severe weather kits for fun. now when it arrived i noticed it had velcro on it, and i was wondering if theres a specific "place" where it fits good? or is it just there to keep it from sliding all over the trunk. did any of you guys get one "installed" from the factory? lol where was it?
