I'm not sure how long ago this was...but TEIN in their website said in a huge banner stating that somebody is making knock-offs of the TEIN S. Tech springs. They had pictures of the comparison of what to look for, color, sticker etc. I did not say TEIN made the knock-offs but someone is trying to copy them to make profit in Ebay. Trust me they looked pretty close to being Teins. I'm not saying all of them on Ebay are knock-offs. You just got to watch out. You get what you pay for.

 

These guys aren't trying to hide that they are selling a knockoff...calling it MUGN and clearing stating "Manufactured by: GTP V*FRP Top Quality Fiberglass"...not Mugen.

 

christ. i'm ready to make my own "hardtop kit" and sell it to everyone too lazy to do some research.

i'll say it again:

this is what you need to do:
1. buy a cheap hardtop. i have an $1800 carbon fiber mugen style hardtop. i'm proud to say it.
2. it may or may not include a rear window. if it doesn't go buy a piece of lexan, trace a cardboard cutout of the window, subtract a 1/4 inch on each side, and cut it out. you now have a window. i passed NJ state inspection with mine. no question asked, by 3 pretty knowledgeable guys.
3. goto some big supplier of random parts like mcmaster carr, and buy the appropriate moldings.
i will do my best to describe them, but you'll want to research the right parts, mostly by pictures and common sense.
-the hardtop to the car molding, across the back, around the edge, spacing the top from the car. its shaped like a "R". flat side sticks against the hardtop, the "D" and the "\" part press on the car. its about .75" wide... get like 8 feet just to be safe. eyeball it up and stick it on.
-the window seals. looks like the regular window seals, but its one big piece. measure, order accordingly.
-the rear window seal. i have no idea. i paid some dude $80 to install mine after i failed miserably at using IIGQ4U's "shit molding" -the install guys words, not mine. he used much better stuff, and a thick black tar like glue.
4. latches. i took my off my soft top. the hardtop has holes, screw it on. i put o rings on the little studs to prevent rattles.
5. plates to hold it to the car. its like 6" tall, 3" wide. has 3 holes at the top, where it bolts to the top. has a hole where the regular soft top would bolt to the car. (i think) its sort of s bent. you could EASILY make one. my cam is busted, so too bad for now. its 1/4 steel plate, bent (done with a vice) and 4 holes. seriously.
6. add it all together, you're done. total cost is well under $400, probably under $200.

that's what my "kit" included, and has worked perfect for me.

biggest issue is finding a hardtop that will fit. i suggest driving to where you're gonna pick it up (look for wholesalers, warehouses) with a s2000 and a pickup truck. test fit, stick in the bed, drive home. mine fit in an 06 tundra's bed, with a flat fiberglass bedcap on, and closed.

my hardtop, with the first set of short, miscut moldings from IIGQ4U:
(the new ones took SIX months to get)
the only things that really worked from him were the plates and rear molding.
i picked out my own hardtop from some warehouse in Delaware (he's in CA)
