I installed my new nismo diff thursday night after work, and I have been nothing but pleased. accelleration is greatly improved, especially when starting out in 1st, no more right side tire spinning, it just goes. the diff makes some noise, but not as bad as a tomei or kaaz. I also probably over did the break in, but it's worth it I think. it feels like a welded diff at low speeds, one tire is always chirping around sharp turns, and I'm having to get used to the handling. which is nice, I was pleased with the handling before, but now it's much more planted. It feels like I can just keep on pushing it through turns. Now if I only had more power, haha. It will stay sideways in the rain now, and getting the rear to slide out is nice and easy. over all, I'm completely happy with it. especially with the price I payed. ($400 brand new)
I have 11 more on the way check it out here
