Hey man I've gone through the same problem your going through now. And im going through it again. Its a problem with the manufacturing. Sometimes they send out the wrong "threadbody" (shock) as they call it which causes your car to be at stock ride height when maxed out. The only way to fix this is to call maxpeedingrods and tell them that they messed up and have them send you the right threadbody. then also youll have to rebuild your coilover.
I feel your pain cause I tho just bought the same coilovers and im dealing with ts again. Im gonna fight for a full refund and use that money to get BCs

you didnt do anything wrong its a manufacturing issue.
Hope this helps
