3 years ago at ZDayZ. The wifey and me did a poker run there. On a couple of the back roads with down hill switchbacks. I had understeer.

The wifey ask me if I blew the turn. And I said no. The front just drifted a little more then what I wanted. I didn't want to tell her I was too hot for the turn, and I BLEW IT!

That's something I don't want to do on the street. Track is another thing. You got no one coming at you. I blew turn 1 at Pitt International North Course. Coming down the front straight at about buck thirty . Grap 2 down shifts, hard on the brakes. Let up on the brakes some, turn the wheel to the left. And keep going straight.

Rejoin the track between turn 3 and 4. I went farming.

This was towards the end of the session. About 20 minutes into it. Overheated the tires and they get GREASY.

I NASCAR they call it push because car wants to push through the turn. So Rusty's comment that you aren't driving hard enough refers to how aggressively you take a turn and that can be at 15 mph. It is about your inputs, speed into the corner and power out of said corner. So with your tire combination and the weight of the front end of the Z it is going to understeer when driven hard or at the limit for your tire and alignment setup.

I think I know a little about vehicle dynamics, no definition needed. And to repeat, regarding the OP's street scenario; I have no understeer.

Coming in hot!!!! Good job on keeping it collected while mowing the lawn and away from the wall though.

My lowly 100% stock settings keep me in control on the streets. We're perpetually stuck behind suv/cuv drivers here in Portland, so it's rare to actually enjoy any corners, BUT, is the conscensus that aside from tire choice, is the front sway bar the next best thing?

I actually like the compliance of the stock suspension / or have just learned to live with it

Update: had the rear sway bar installed at full stiff (was previously running stock bar); full soft front; camber front at -2. Understeer solved! Went with these settings at the suggestion of the local shop. However, as many on you said the back end now wants to kick out with the slightest bit of throttle input.

Turn in feels great, but mid-late corner has me hesitant to give more throttle to power out the turn. I guess this would be what some call over steer.

Albeit, I need to put some more miles on the car to really get a full feel of the new suspension setting, I’m already thinking of going full stiff on front and middle setting rear as initially suggested.

If you're not planning on going to coil overs, get the stiffest front sway bar you can find...Hotchkis. Body roll will reduce but you'll soon start to see that on a staggered wheel/tire setup the car will still understeer somewhat. Switching to a square wheel/tire setup will pretty much get rid of that and your eyes will be opened to a whole new world, this was how the engineers really meant for this car to be driven.

Anyway, I couldn't agree more about the compliance of the stock suspension. It really is better than most people acknowledge and in terms of performance, there's a lot to be had there before claiming that the OEM struts and springs are the bottle neck.
