'76Z

I'm looking to improve the suspension on my '76z. I'm thinking about going with KYB gas struts and urethance bushings. I've been told the stock springs are among the best. And i'm not too sure i want it too much lower anyway. What do ya'll think? Any advice on wheels? I would like to switch to a low profile tire but don't want huge gaps in the fender wells. All the wheels i saw on the zstore.com were 17" isn't that pretty big for the z? I really don't know too much about this aspect so any advice would be greatly apreaciated (sp?)

I'm useing the car as a daily driver in the south with wide open winding roads. I would like to in to Autocrossing one day. TIA
