Yeah but no...
There is not a chance in Gods green earth that would I bolt a 8 lb piece of aluminum to the front of my car. If it was carbon honey comb it would likely be less then 1 lb and it would not bend the frame of the car if you bumped a curb or a steep driveway enterance.

I will be making a carbon splitter, some dive planes and a rear wing for my car when I get some time, but untill then I have light nose.

You can also get the car corner balanced. With all the stiffening going on, you're going to start snapping stock drops links so budget for some adjustable ones. The motor mounts and tranny mount also have too much give and should be replaced There are several options available and not very costly. These are easy DYI projects. The stock shifter is too vague, upgrade to the 997SS (a simple but time consuming DYI, but at least you don't get dirty)

I am not paying for the installation at all as I have the ability to do all that myself, the only extra cost is a second alignment. For me all this is R&D to see what helps what. Also in the mix engine and tranny mounts and shifter will be done.

I have the rear adjustable toe lock kit, but no dog bones. Not sure on what alignment specs I have, but will start with an alignment and go from there.

I have H&R springs and the car scary to drive over 70mph..Need 2 hands on the wheel at all times. Whatever you do, do not buy springs..... I'm gonna go back to stock suspension this weekend until I order a full suspension set up!
My e46 m3 handles like an F1 compare to the TT.....

If you'd paired some Bilstein HD shocks with your springs I bet you'd have a different opinion.

Yes definitely this is what I posted as well, though I'd highly recommend changing the front bar too.

Negative toe-in (toe-out) will give a very "flighty" drive. You might not notice it until the wiggle results in a few feet of lateral movement - happens real fast at high speed and gets your attention.

Any suspension work requires an alignment. I doubt new springs "caused" problems as much as the new alignment resulted in a change in chassis setup.

Going from about 0.1 toe-out to 0.1 toe-in made a remarkable difference. The flighty feeling was gone but turn-in was still crisp. That much difference made such a difference.

So first, get a good alignment from a shop that works on Porsche and knows what what you mean when you say "corner balance". If they say "whut?" take it elsewhere.

At 70-80 mph it feels squirrelly and jittery. The alignment was done at a reputable shop, so I am not sure what the problem could be.

Any advice or ideas on what my alignment settings should be?

Besides the alignment don't overlook aero; the car should be raked down rear to the front (lower at the front than back). I've been told this effect is exaggerated with additional factory aero. I'm running 19's with KW coil overs, my car was more nervous at speed when I had less rake. I also softened the dampers for the rough roads in Phoenix, If you're running the 25 series rubber like me you need to soften up something else.
