Problem with Apexi coilovers

[APEXi240]

I am extremely pist right now. I have a set of World Sport Damper coilovers on my car, and they have been on since May. I'm not exactly sure how many miles, but its definitly under 10k. My problem is that the rear struts are already blown, which has made me extremely angry. I haven't done any drifting, haven't take my car to any tracks, haven't really raced on them at all. Would there be any reason for this to happen? My car is lowered quite a bit, but its still only about halfway on the threads of the coilover.

Is anyone aware of Apexi's warranty info? My instructions and whatnot were in Japanese so I threw them out, and I looked on their site, but didn't find any warranty info. I'm gonna give them a call on Mon, but I wanted to see if anyone had any info they know of.

Are the World Sports rebuildable? I read somewhere that the N1s are but I'm not sure about mine. If they are what type of struts would I have to use?

Last question, sorry for the long post. Is it possible to call up say Tein or something and just order the rear two coilovers (if worse comes to worse)? Any help would be GREATLY appreciated. Today is one of those days you just want to break something, or kill someone, nothing's gone right all day, and this is the icing on the cake.:bash

All I know is that I was checking out a site with a guy who had ApexI WS's and an SR in this area, his site has since gone down. Anyway he could read japanese or knew someone that could and in the instructions it said that a part of the coilover was supposed to be removed before installation. Im not sure what part but he scanned the instructions and showed the exact piece. Did you remove anything when they were installed? (BTW I have NO idea why ApexI would make coilovers and put a piece on that was supposed to be removed)

I don't remember really if I removed anything off the coilover. I disassembled the mount/bushing off the stock spring/shock to put on the World Sport. I wouldn't understand what needed to be removed, because it came completely assembled.

I guess this doesnt answer why the backs are gone but it tells you what piece was supposed to be removed. Too bad his scanned instructions are gone.

Thanks. I don't see how that spacer would ruin my shocks, but maybe. Does anyone know if they are rebuildable, because from what I've heard some coilovers are and some aren't.
