Thanks for the replys. I know that the gtr 4wd isn,t constent like a wrx but when i try to do a launch at 5000 rpm it just spins the back tires, also when the car gets full boost in second gear at 5000 rpm it spins the tires all the way to 7000rpm. I've noticed as i have been driving when it usally spins in second gear at 5000rpm it got full traction 4 times. So do you guy's think it the ATTESSA clutch plates?
