Nopi contacted me today and told me that my KYB's are on back order until the end of the month.
My question is, should I wait for them, or should I cancel my order and just install my GC's with my stock struts? Will this be a good setup?

Save yourself some time, work, and money. Wait for the KYB's or get them from somewhere else (try www.p-s-t.com). I was kind of like in your situation, but did the struts first then the GC's. It was a pain to do the installation twice, and not to mention getting an alignment twice.

Wait and do it right. The oem struts will not work well with the GC springs. You could cancel your order and find some real struts like Koni's. ;) It's just me but I like the Koni's much better and I think they work better with the GC. you can weld on the proper collar after cutting the stock perch off the oem housing. Makes for a nice install.

Like mentioned before do it right the first time. You will not regret it!:D
