Hey guys, I own a 1jz Soarer with R154 trans. Recently the clutch started slipping... I think it hasn't change since car was bought let alone since it was imported... I am trying to get an idea of what clutch would be best suited for my goals but would have a nice, not too aggressive pedal feel...

The goal is 400hp 450 ft lbs torque to 550 hp 500ft lbs of torque.

Currently the car has 440cc injectors stock twins. It will be tuned via a SAFC and 16psi of boost. Then 18 psi of boost on a HX35 setup... (Upgrading the injectors if hp goes to 500)

I need you guys experience on this one. I've felt a r154 1jz with the act 6 puck disc and HD plate... Feels Jumpy and Stiff! I've heard about Southbend but haven't seen much people leaving feedback about them. Also heard someone talk about RPS... What do you guys recommend?
