imo...i think the seibon isnt considered a knockoff...but some people think its cheap because it looks exactly the same as mugen.....seibon is a good known brand too? the apr is getting more popular...the 2 wings costs around the same...seibon costs a little bit less....
which one looks better?
here are some pix


this is the seibon one




the mugen doesnt need pix because it looks exactly the same as seibon
its just the brand.

 

chek in the Gallery Some Pics Of my Car! Seibon Wing, Looks HOT!

 

Mugen style definitely

 

I'm not big on this HUGE wings... unless you're gonna track your car.. i'd get something more subtle...

 

seibon

 

don't get it twisted, seibon is like the king of kick off, not all of their stuff fits that well neither.

if you going to pick it up in person, check the weave and finish, no two cf parts are exactly alike

rumor has it(it was on honda-tech) vis and seibon get their part from the same factory in china, it was from a third party's mouth(who happens to be in the composite/cf/fiberglass auto part business as well)

 

thanks for all the reply guys.
im now deciding on the oem 04 rear wing too!

 

the oem rear wing is awesome...it really looks like it should have come with the car from the factory. i look at other s2000's now and they look naked.

 

Neither
