Hey All I've got some FM springs as well as some FM bump stops for my 1997 Miata. I plan to get some bilsteins to go with them (let me know if you think otherwise).

My main question is should I use NA or NB top hats for my set up. I have the NA top hats currently on my car and a set of NB top hats from a friend. When replying could you elaborate why one or the other?

Thanks
