New Koni FSDs Arrived, Alignment Settings Recommendation Please
Hi all,
My Koni FSDs arrived and I will get them installed soon, along with an alignment. I'm hoping some of the experts here can help me with alignment settings to ask for. I have looked at several threads but I was hoping get some specific help.
Car: 2008 Z51 Coupe M6 15,000 miles
Goal of alignment: Carving country roads aggressively with traction control off, no understeer. And of course normal street driving. I don't plan on any tracking at this point.
Sway bars and springs: Stock Z51
Shocks: Koni FSD
Tires: PS 2 AS
Lowering: I don't think I have any now but I understand that the Konis will lower it a bit.
At 15,000 miles, are there any other suspension components I should be checking while I get this work done?
Thanks!

I have the FSD's also on a non Z51 08 model. I did change the sways over to Z51 but kept stock springs.
I love the Koni's, much better than the stock shocks. I did test drive the Z51 model and did not like the ride. I think you will be happy with the switch.
I went with Pfadt's street specs. look it up. Some say it will cause inside tire wear up front. I tried a zero camber alignment and did not like how the car handled at all, kinda scary.
Mine is not a DD and I love the alignment.
-0.8 front camber
-0.5 rear camber
as close to zero as you can get with the toe front and rear.
Just google "Pfadt street alignment"
This will give good street performance for the corvette while taking into consideration tire wear.
The toe is what really scrubs the wear on the tire.

I think there is an extra "0" in those settings. 
Here's the Pfadt recommendations. You can obviously set yours between the Pure Street and Street/Track if you want more than the Pure Street offers. The main thing is get the Toe settings to "0.0".

I'm mostly interested in improving the ride.
Some people whom I respect have said the FSD's are a significant ride improvement over the stock Z51 shocks. Other people whom I respect have said "no difference".
It's confusing that honest and intelligent people have such different opinions.
We all have different butt-o-meters, I guess.

That's what I did, Pfadt street with zero toe, not as sharp as full negative camber but tires cost a lot.
