Jaime, The coilovers are from Mike Gibson (SCCA). They are good quality and easy to install. I sectioned my struts 1.5" and used 10" 175 lb. springs in the front and 8" 200 lb. springs in the rear. It was a lot of fun to install these. I did have problems getting " the most stuck strut ever " strut cart out and ended up having to buy an entire front suspension off one of our members here, but all in all, the conversion was easy. I also used Tokico 5-way adjustables. I needed some spacers (just some washers) at the bottom of the strut tube to raise the cart to be able to tighten the gland nut down properly.
For my application, I needed to cut and weld, because I sectioned my struts. FYI, it is possible to just place the threaded sleeve on the weld from the original spring perch and not have to section the strut. The only cutting you would do is cutting off the old lower spring perch. IMO, I guess you wouldn't have to cut it off, but it may look kinda tacky if you left it on.
About the pictures, yeah I would like to see the coilovers and my 17"'s on my car also , but I haven't put the suspension back on my car yet. I'm still waiting for my bumpstops from MSA to complete the conversion. I will post pics when I get it all done, hopefully sometime in the near future, but I'm in no rush to fully complete my Z, for the stupid salt trucks dumped stupid salt on the stupid roads around here .
!M!
