Lots of Miata owners keep the top hung from the garage ceiling using a hoist. I'd bet you could modify the hoist for the S2000 top. I've installed one of these for a friend and it works pretty well for the Miata top.

I'm suprised that no one has replied with something useful ... Anyway, I get help from my girlfriend to remove the top then bring it into the house. I have alot of rooms and one room downstairs near the garage with the full doors open provide easy access and storage. I place the top on two mattress spread out when I don't need to use it.

I have the JDM rack as well but I find it very stupid, when I try to place it properly it will just get fingerprints all over the top and that pisses me off than putting it on the floor with the mattress. While putting it on the floor is also much safer, I fear the top might just accidentally fall off and it will be another financial punch-up.

 

The page says it's for Miatas only. Do you have any ideas about what needs to be modified in order to work for the S2K hardtop? Is it just the length of the four straps?

............I just received this reply from Moss Motors (who sell the same hoist):

Ours only fits the Miata. We have tried it on BMW, Mercedes, and a host of
others with no success.
