There was also a writeup on the install in Vette Magazine, on a C5. The install on the C6 is similar.

I took no pics of my install, but it's straight forward, you can get tips on shock absorber installs over much of the forum, and these were the instructions I used as opposed to the official instructions from Pfadt.
I chose these over the Bilsteins for their adjustability and wanting to eliminate wheel hop. I also did not want a stiffer ride "full time" so I opted for the adjustability. These have 16 different settings
I am on currently on Nitto NT 05s, which of course offer a smoother ride than the stock runflats, and the Pfadts on the 6 setting, make it even smoother. The stiffer settings give the car even more of an on rails responsiveness, though I would not want to run it on the street in the higher settings.
I have tried a variety of settings with these, and they have potential. I like them. So far after about 100 miles, the only problem I ran into was the set screw on the orange adjustment wheel getting loose on the one shock. There are two of these set screws, and one must have been loose from the factoryl as the adjustment wheel would spin w/o adjusting the shock. An allen wrench to tighten that set screw did the trick.
The shocks can be adjusted with the car on the ground, the rears are easy to get to, the fronts, easy to get to by turning the front wheels to lock on either side.
At any rate, those considering changing shocks, might want to consider these.

No more wheel hop?
Also, would you say it smooths out bumps on the road much better?

Just installed some myself and have @150miles so far.
Came from C6Z shocks and the performance difference is honestly not that obvious right now. I havent driven the car to hard as I wanted to make sure all was tight and the new brakes were stopping as needed. I too went with Pfadt for the adjustability. The shocks do seem more efficient with the car being lowered where the Z shocks would bottom very easily over hard expansion joints, etc.
I went with a 8 front setting and 10 rear setting. So far this seems about right. I hope to get to the mtns this weekend to really see how they work compared to the old shocks.
More to come.

Me too!!!!
I am just finishing up my installation of Pfadt adjustable shocks AND Pfatty competition sway bars. My snow just melted and the roads just got scrubbed clean by all the rain so I plan to be out this weekend doing some testing. I have a new shifter to install also, but that is unrelated to this thread.
I should have more to add in a couple of days!!

That's my goal. I'll know when it goes back to the drag strip and I am able to make adjustments as needed, if I was successful.
There are a few people in here who have used the QA-1s to achieve a similar result, ie reducing wheel hop. Here is one.

Stiffening the fronts and softening the rears should help with the wheel hop.
Yes. But my car is on non runflats too. I am sure that the two together, make a difference.

great mod
I have set the shocks varying from 4 to 10 on street, and from 12 to 14 on the track.
My experience tells me 4 is VERY comfortable and compliant for the street, and any higher numbers not as appropriate. I suggest 4 for the street.
For the track, I need to vary from the numbers this season I have already used last season , but 14 was a bit too unforgiving on the track; 10 or 12 better for my sense. For kicks, I plan to try 4 or 6 on the track at least once see if there is more "bite" in turns - but we will see if it accomplishes that at the expense of car control.

I tried 6 to start with and it was okay- not harsh and still fairly smooth.
I tried 12 and it was harsh on the street!! I'm sure that would be ideal on the track, (or a spirited back road blast ) but WAY too much for a date. Might be too much for the interstate as well. I should point out that I have Pfadt's Competition sway bars as well, and that combined with the 12 setting may be pretty stiff.
I spent the rest of the weekend on 4 but am going to try 8 and 10 for my next backroad blast. I AM LOVING THIS ADJUSTABILITY!!!!
Oh, the MGW works great and no rattle!!
Did you guys check/set your ride hights??

Tried 4 all the way around and it took some getting used to. Car rode almost like my Cadillac. A little too soft for me at first, but I left things as there were and it's not bad.
Someone here posted that 8 all the way around was about the equivalent, according to the dynographs, of the stock '07 and up, Z06 shocks.

No wonder 4 seems soft to me.
I will be again taking the car to the road course and the drag strip and this is a big part of the reason why I bought these, so that I could adjust back for the street as well.

Of course some of this is subjective, but in my experience running the front equal to or less than the rears will make the steering twitchy, i.e., oversteer. I usually run the front at one or two settings higher than the rears to balance the car. I can't imaging how exciting it could be with the fronts set 2 clicks LOWER than the rears. (this assumes an otherwise stock suspension)

Well, I hit the mtns on Saturday for a quick fun run. As I stated above Rob from Pfadt recommended I try the 8F/10R setting so thats where they were at. Once I got into some turns I could tell it was not what I wanted. 2 clicks each shock up to a 10F/12R setting and off I went. WOW!!!!!!!! Car felt so freakin good. The car went exactly where I wanted it when I wanted it to. I was actually able to ease into the gas harder and sooner than ever before. The level of confidence with these shocks is a huge difference for me and my setup.

Pfadt were at one point advertising an in-cockpit adjustable shock with the spherical tower bearings. Whatever happened to these?? The inability to adjust dampening in the cockpit has preventing me from buying these (or at least, the promise of being able to "soon" has!)

I have these shocks on my 2010 Z ( fronts 8 rears 9), and it's a real good improvement over stock. Stock, the car felt too soft, and the back end floated around too much when taking the corners..

I agree, the rear hops around quite a bit in the corners when it hits small bumps or ruts in the road. It is very alarming
