I have had experience with their Carbon Fiber products, including their hoods. They fit like a piece of dung. They give off a piss like smell. Honestly, it really stinks, or at least mine did. Their weave is awful, i had 4-5 weave imperfections. The gel coat faded to a dry layer that was unrepairable. It also had deep orange and yellow marks. It fades quickly, after 6 months when i bought it new it turned green... Just my .2 cents. From that, i will never buy any more of their products.

 

the memory fab seats are alright, but they don't come with rails, it look like the seibon unit comes with rails,

I haven't heard any of those weave problems that you explained, but frankly with a cf seat, I don't care if the price is right, i'm not going to see it...

also, im pretty sure this will fit an S2000 will someone who doesn't hate seibon answer if they will? also, how much do they weigh? I can't find info on that so im hoping someone knows...

 

theres the f1 race seats on Honda-techs sponsor forum...its around 500 for a set of fiberflass ones and look like the spg and spoon seat...someone put it in their s2k and said it fits good with A LOT of adjusting to the seat rails...forgot which rails he used..try looking it up and pm-ing him
