Yah, unfortunately,
The ATTESA system as a concept is one that’s used now by most of HiPo manufactures like Porches etc. I don’t want to lock it solid, front to back, nor simply strengthen the clutch packs, Iv never driven a R34 GTR, but am told the system is a lot more progressive and adaptive to wheel spin, and how tight it push’s the packs together. You can watch from footage of quick examples how it effects the attitude of the car (understand the E-diff has a role here, but lets leave that out of the equation for now)
Any other thoughts
