Hi Everyone,

Well, as winter approaches in NY, I am getting the most out of my Z (260) before it goes into hibernation.

I have noticed this week, that i am losing traction & sliding the rear around corners more than usual- specifically, i go around a 90 degree corner near my house- in 2nd gear at about 30mph (3000rpm). I accelerate through the bend, and the tires really begin to squeal the back starts to come around if i keep the pedal down. I also noticed that on the offramp from the expressway- about a 210 degree loop- the same happens in 3rd at 55-60mph (but that road surface just changed from blacktop to concrete).

The tires are Firestone F570's 195/70/14 the PO mounted and have only about 4000 miles on them. Maybe i should move to 205 or 215's?? (more rubber on the road) Or change to a "stickier" street tire?

It's not like i just dropped in a V8, i did pull the smog pump & remove the emmisions and manifold coolant lines last week & went to the early balance tube, but i can't believe that would lose enough weight or gain HP to cause these symptoms!

Maybe i'm just driving like an idiot:cross-eye !

Well, thanks for any input, and cross your fingers that it doesn't snow in NY this year....

About your driving.....:devious:

Just kidding. How much air pressure are you running in the rear? Try dropping a couple pounds out and then see what happens. You might just be running too high a pressure and the tires are loosing their grip because of it.

Of course a wee bit wider tire won't hurt anything. Especially when you are playing "road racer" on the on-ramps...

Seriously though, try playing with your pressures a little. It might make a big difference.

I'd go with about 32 to 34 so if you are running any more than that it might be half the problem...

Well, gotta be honest ....the tires "look" okay, but i couldn't begin to tell you the actual pressure:stupid:

I also wondered if i may have lost some swaybar mount or somesuch- heard some of us have torn those loose when driving these cars the way they like it:classic:

My 73 had 205/60's (or was it 215/60?) That would squeal if you really really tried, but nothing like this..

Oh well- nothing like an excuse to go putter / test drive over and over. It'll beat stripping kitchen cabinets this weekend. Would one of you talk to my wife about this...?
