spec is a great clutch, bang for the buck. we've used them in the enjuku cars for a while now. if you're going to be a REALLY harsh drifter on it or very high power levels, then you may want to look at the exedy hyper single. For a daily driver thats sometimes drifted or dragged, honestly they hold up fine (stage III is the way to go). VERY streetable, and they last a long time.

We're going to be testing a dual disc setup from Spec very soon (maybe this weekend). Cant wait to find out the results.
