Thanks for the responses guys! Since I have no clue what front struts are in the car I think I will tackle this in stages.
I would like to put adjustable spring perches on the rear shocks and keep the 140# springs for now.
I am going to install front Konis in raised spindle strut housings.
Step 3 is a stock front sway bar.
Then I'll drive it around and try the 100# springs for comparison.
Here is a copy of Kevin's message to me and my response:
Hi Kevin.
The Koni instructions were just a half-assed pictograph showing which way to turn the adjuster for stiff or soft. Not super helpful. I don't know what front struts are on it now. I had internally adjustable Koni reds (orange?) in the back and one leaked itself to death. NOBODY would rebuild them or sell me parts for less than $300 each, so I just bought a pair of yellow sport Koni adjustables from Pelican.
Before I ordered the new pair, I pulled the decent looking KYB's out of the parts car to tide me over while I figured out the parts situation. The KYB shocks had the 140 Weltmeister springs, and I figured I'd give them a try. Well, the ride was as awesome as everyone says. "Harsh" is being nice. So I buy the new shocks and figure I'll try the 140 springs on the Konis, and I kind of like how it rides. MUCH smoother, but still handles well. Sits a little higher than I would like, but not horrible.
Part of the problem with my car is that it was lowered a little. In the front, they just backed off the torsion bars, so I'm losing some travel and it feels like it bottoms out occasionally. It also has some bump steer. Big surprise.
My plan for the front was to get another pair of struts, move the spindles up 2" or so (my son can TIG weld it back together) and put a set of yellow Konis into them.
I would also like to get a front sway bar, but I wanted to get all the other stuff done first.

Hi Todd, I remember when I bought my Konis the instructions stated to NEVER set the valuing at full soft or full hard. Seldom mentioned. Are the front struts housings loaded with KYBs? I had put 21mm bars up front. Misery. Felt every expansion joint. Now stock Tbars, Komi red ext adj, 100# on threaded collars, F&R sway bars and Elephant polybronze bushings up front. Dreamy on the freeway. Plenty smooth and predictable in corners. I figure that aside from the struts /springs the brainiacs at Porsche knew what would work the best across the board.

PS. I have a spectacular spring compressor and don't mind experimenting with springs.
