So I have a 2005 S2000; pretty bone stock. If I were to buy a used hartop by itself, would I need the installation kit? My friend is telling me that the 2005's don't need it, but they sell them on www.hardtopguy.com so I'm not sure. http://hardtopguy.com/store/customer/produ...4&cat=92&page=1

 

You will need the side catchers, defroster wiring, and new trim brushes. If you're buying a used hardtop you can probably get these off of the seller's car. If not, you'll have to buy the kit from hardtopguy.

 

Thanks for the info!
