Lowered...need anything special for alignment?
After lowering the Z (on stock bolts), will I need anything special in order get it aligned? For example on my Mustangs I always needed Castor/Camber plates because the stockers weren't adjustable. On my Lightning, I need camber bolts (again for same reason). Can an alignment shop successfully align the Z without any special aftermarket devices?
Thanks!
Thanks!

You dont need to so anything special except trying to get it on the ramps for the alignment 
.
I lowered mine on stock bolts (cut 2/3 bushings in front and back) and i had a hell of a time finding a place that could even get the car on the ramps.

At the shops that cater to the people who race (autox/track). I've found they always have sets of 2x10s or some such setup. So that they can place them in front of the rack so you have a gradual incline. They are also the ones who won't give you grief when you show them the specs you want set on the car.

With a lower car, the alignment setting still should be same as stock setting, correct?
Man, I want to lower my Z06 so bad, but am concerned with ride quality degradation as some owners have expressed.

I dropped my car close to an inch on the stock bolts. I went to a local company that specializes in racing tires, wheels n alignments. They are set up for lowered cars. I had them set the stock alignment which they were able to look up and corner balance the Z. I notice no difference in the comfortability of the ride. I've been going to this shop for 15 years for alignments on many different cars.

I ended up going to NTB, i got a good deal from a friend ($43) but it took 2 days. 1 day i showed up and it was too low to get on the ramp, and the 2nd day my friend brought some wood so the car would be able to get on the ramps.

How does lowering affect the ride quality on stock bolts? Stiffer?
It certainly makes the car look better which is only one half of the equatiuon. It must handle better too with a lower center of gravity. A "Rake" is needed to. At least .5" higher in the rear for high speed stability.
