Well, what kind of mods do you plan on doing? If you're going to get a new clutch, you may as well do it right the first time, and get one that can take the abuse you're gonna throw at it.

Exedy is a good clutch (stg 1 is all you need, as it is capable of up to around 300 + hp) ACT and CM are both good. This is kind of hard to answer as there are MANY different kinds, so you need to tell us what you're looking to do.

BTW: A D16z6 is not JDM, that would be the D15B
