So I got rid of the 245s on the front and went to 275s and my problem pretty much diminished. 2 different solutions to the same problem? I don't know, but just a thought for anyone else reading this.

Interesting. That would make a lot of sense since the contact patch is larger. This may be a necessary upgrade for people going to the track or are going to be exploring the limits of their car? Even though I did the alignment and adjusted the dampers, I don't know if I'll see the same thing when I go to the track.

Doesn't take much of an alignment difference to totally change the feeling of a car.

On my R33 skyline I went from 0 rear toe to 1mm rear toe in and it totally killed the liveliness of the rear end, it was BORING to drive. On my R34 I told them to toe out 1mm at the back and it was beautiful (factory spec is 0 to Out 5.2mm!).

I have noticed some skittishness on the Z34, braking from highway speed. The car was almost new and maybe the brakes hadn't bedded in yet. Hasn't happened since but it's in the back of my mind.
