Canadian Members - Coilovers

Guys, I'm trying to help a buddy with a 2002 LS1 camaro...The car used to be his uncles who has now passed on...There appears to be coilovers on the car on all 4 corners...and they want to raise the vehicle up about 1/2 inch or so. We don't know what kind of coilovers they are, and they have no idea where the keys/wrenches are.

How can I get ahold of some keys/wrenches...and how would I actually adjust the coilover itself? Do I just turn the bottom plate thing a couple turns until we are happy with the height?

Seems to make sense, but I think you would get a better answer by posting a picture in the Suspension section.

I'll have to take a pic next time I'm under his car then...
