It was posted a while ago, I went and dug up the thread... Take a look at this.. I think looking at ratings it seems HKS is the best setup overall, with the Aragosta 2nd, and Tein 3rd. HOWEVER, Tein has an EDFC...

I've read a few other tests with other cars and the HKS setup usually does very well.

I dont see any testing on the JIC unit. I think they deserve much credit for their design. Hopefully a few more board members will chime in and give their reviews.
