I have never heard of dxd clutches.
I have a Spec 2 clutch in my wagon. I had Mike at www.AZPinstalls.com
get it for me.
I got over 80,000 miles on the old Spec 2+ before I replaced it when the new short block went in.
The Spec 2 has a great feel to it.
188k, 5/20/12 new ej257 short block, 8/20/11 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. CHECK your oil, these cars use it.
