I'll summarize my experience with them as my conclusions are a bit drawn out on that thread.

I used the KYB GR-2 struts and the KYB Gas-A-Just shocks on the rear.

Apparently, there is no KYB GR-2 shock.

I bought the set expecting there to be but I received the Gas-A-Just for ther rear.

They are excellent.

Once I deflated my tires to the manufacturer's recommended psi for front and rear I was very pleased.

I will also say that the full effect wasn't achieved until I also replaced the steering damper.

With all that done and some new strut mounts I highly recommend the KYB option.
