Ive got the k1 body kit with the k1 spoiler. The extra weight of the spoiler wont let the hatch stay open, it was slamming down. Some of you on this site referred me to liftsupportsdepot.com and I had ordered a pair from them. They were recently installed and still do not keep the hatch open. So I am told that the Trd performance package uses a heavier spoiler and those lift supports are a higher pressure unit. Does anyone know how I can get these lift supports? any websites or what?
