Hey,
So as the title said, I have a Koni/Strano setup on my car. I also have an adjustable torque arm, but my car definitely feels like something is off driving on the highway -- it drifts a bit to the left and it literally feels like the car is stuttering over broken pavement driving on the highway above 70 mph.
I got the car aligned by a local speed shop, but something tells me they didn't quite know what they were doing. I was just curious if stock alignment settings would work for this setup or are there better settings out there?
Thanks

I guess my first questions are what did they set it (or supposedly set it) to? Where are the shocks set, and what are the tire pressures and sizes (it matters).
Has it always felt this way, or changed after the alignment?

Stock WS6 tire size and pressures.
-1.2 camber
+5.5 caster
1/16" toe in
I forget the term but the tires are set to 0, whereas from the factory they were angled outwards a bit (can't recall that actual term sorry)
Shocks are set at soft
I don't recall whether or not it was this way before the alignment honestly.

did you reajust the TA angle ?
the camber is lower than I like ( I like + setting on camber for street running, if auto-x I might go a little -) I like close to OE specs wheter lowered or OE heigh. With that caster setting you should pull a very littie to RIGHT,what is your rear thrust angle? do not think it would cause your problem. how is your tires ? and pressure ?
:.....it drifts a bit to the left and it literally feels like the car is stuttering over broken pavement driving on the highway above 70 mph. "
I think a tire with a broken/twisted belt is problem
even a new tire sometimes will act up try crossing the 2 FRONT tire and see if any differance in driving( better or worse) IF no differance try crossing the REAR tires ,check for differance , this will NOT damange the tires for a short time

You kind of left out some details that I asked about, and that do matter.
If it's a street only car, then I'd not run the -1.2 camber. That will make it more prone to following ruts. As for the shock settings, how did you end up at full soft, particularly on the front. It's not what I recommend, though if like it best that's cool. However too little damping for the springs is a bad as too much (worse actually). And I run my Koni's higher than that by a good bit in front.
Details, let's have the details.

Also what tire pressure are you at? Don't say "stock", actually go out to the car and check it out, it may be way too high, some shops for whatever reason like to crank it up. Should be around 30psi on all 4.
Stock camber may make the front tires wear on the outsides, I know mine did. Im running -1 camber and loving it.

The shocks adjust rebound. A lack of rebound to control the springs is the same as running a worn out shock on a stock spring, and can ride worse. Turn it up some, particularly the front. See what happens.
I'd be happy to give you more specifics, but I need answers to do it, and I'm not getting those.

"soft" rebound doesnt = soft ride, and stiffer rebound doesn't = stiffer ride. Turn your shocks all the way up and count the number of sweeps you have, then back them down half of what you turned up, that will be a good starting point. I personally drive around the street with them 3 sweeps from full hard in the front, and full soft in the rear.

As far as tire pressure, I said stock b/c stock rate is 30psi on all four tires, which is the first thing I check before coming on the boards to ask this question. I didn't just presume they were stock.
I've read the -1 camber works on other threads as well. What about the other settings? Are they stock with camber being the only difference, or is everything different on your setup?
