Ok guys installed 3k stall and tcu Friday. Installed UPD toe arms yesterday. Ran out of time and patience for camber arms (gonna wait on coilovers for top camber bolts). Got to drive car today and only way to describe it is it feels like rear tires are flat. Both from a stop but also at 80mph on interstate. Punch it and rear end is really unstable. Running my factory size tires for winter with summotomo(sp?) tires. Same motion every time car goes left then right like I describbed tires flat or being in a boat with small waves? Any idea?
I know it's putting more power down now. Realize from a dig its squirrelly but at 80mph it's pretty unsafe??? Punch it to overtake a slow car and have to let off to resettle??? Thanks guys for any help

After installing the toe arms, do you need an alignment? If so, maybe that is the solution?

Alignment is done.

What did the alignment set the toe to? I know after I installed my arms and before the alignment, my settings were far enough out of whack that when I stomped it, it was like I was driving on ice. I had all the toe dialed out and now it burns the tires nice and straight.

The rear suspension flexes out under power, needs a little toe to compensate. Mine did the same thing when I straightened the alignment too much.

If your rear tires are toe out under hard accel your gonna rear steer,which is kind of what it sounds like your describing

Ok i'll get it back on alignment rack. Didnt save numbers just adjusted till in green. Somewhere around 1degree if i remember right. Thanks guys.

you wouldn't happen to know what they set your toe to would you?
Any one have there alignment specs handy? Obviously our machine's settings aren't gonna work. Thanks

I have rear links (different brand) and have my toe set to 0. No issues.

Definitely toe issues.

Here are my last alignment specs after installing KMAC bushings. Rear steer is completely gone.

I had them set toe to 0 and camber at -0.5.

Usually a bit of toe *in* is a good thing on RWD vehicles. Is this something that anyone has tried?

On the chart it is suggesting a bit of positive (which a + number) toe.
