I am one of those who find the power oversteer before the Attessa kicks into action a hairy experience. So, I installed the controller - HKS Electronic Torque Split Controller. What it does is as stated by Guy. I could set the torque split up to 50:50 ratio. On the track, I stick with 30:70 ratio and it works wonders. The car would go into a corner faster than when the ETC is switched off and on coming out there's none of the oversteer shite I fear so much! To me, it is the single most important mod I did to my GTR!
