I think its official. My tokico struts are garbage after one month.I installed them with H&R SS. I drove really hard for a bout 200 miles and I think I quickly wore them out. My advice would be to get 5 the-way adjustables in the beginning for anyone trying to lower their car on a budget. I know I will have my car for atleast another 10 months and It will drive me crazy to handle the way it is now. I think I am going to try to get away with buying only the fronts. Everyone just buy one set and one install and have one alignment.
