I need to replace my struts on my 76 280z and was wondering what would be the best buy. The car isn't my daily driver so "comfort" isn't too important. Although, obviously I don't want my teeth to rattle loose from my skull. I drive it in the summer, mostly on weekends. Recently I discovered SCCA Solo II events and would love to put my z through the course--my Ford Focus just isn't cutting it. I've been looking at the adjustable Koni struts with Ground Control adjustable coil-overs (Eibach Springs). Are the Konis truley adjustable? Will I notice that big of a change or is the knob on top a marketing scam? I'm really impressed with the CG coilover kits, but totally lost on the struts. Does any one have any advice. Oh, one more thing... I'm not loaded. So, money is somewhat of a concern. I'm trying like **** to keep this between $600-800. Thanx in advance for the advise.
