Info on swapping shocks and the part number for both types of shocks are
posted on the NOWROC site half way down the page:

Let me add to Fred's reply below. I do not suggest the Gas-A-Just if
your
using the Nismo front springs. They shocks are all rebound and with the
stiff springs, your front end will bounce. ask me how I know. They do
add
ride height, so those concerned with the "Slammed" look should stay
away.

But they were great with the stock springs!

I got some pretty good replies about shock absorbers, and here's the
best
one from one of our list experts:

"GR2s are low pressure gas shocks and the Gas-adjusts are high pressure
gas
shocks. That's why you gained some ride height. The extra gas pressure
is
like
adding some additional spring rate and raises the ride height a bit.
Also
sounds
like your old shocks were worn out and were not doing a proper job
damping
suspension movements. With shocks (as opposed to struts) you can do a
bounce
test. No matter how hard you bounce the car, or how many times you
bounce
it, if
the shocks are good, as soon as you stop bouncing it the car will
smoothly
stop
oscillating. If you get the car bouncing up and down and stop after a
push
down,
the car will at most go up and down one more time and then rise slowly
and
stop
at the normal ride height. It may not even go down, it may just go up
and
slowly
settle to normal ride height. But any other reaction means the shocks
aren't
adequate, or aren't working properly anymore."

So there you have it - GR2's are weak and Gas-adjusts are strong. I
bought
the Gas-adjusts more than a few years ago but hadn't used them until
now, so
I don't know if they're still available. I did a lookup on the internet
and
found this:
http://www.kyb.com/shocks/gr2.html GR2's are for a comfortable ride.
http://www.kyb.com/shocks/gasajust.html Gas-adjusts are for high
performance
handling and response.

> Hi,

after
installing new tires due to a couple flats - 195/60 HR14's - and figured
the
shop screwed up on the wheel balancing. I redid some of the weights and
moved the wheels around.

installed some KYB Gas-adjust shocks, and was surprised that they seemed
to
add 1 or 2 inches of height to the roadster. The old shocks were KYB
GR2's
and didn't seem to have much resistance. I had to precompress the
Gas-adjust
shocks with a floor jack and duct-tape them at the right length in order
to
mount them in the rear.
