What's the general consensus on the "sawblade" design that came stock with the '93s? Personally, I like the look of 5-spokes better, but heard somewhere that the zr-1 style wheels are actually heavier(???!) and add to unsprung weight. I have the 1993 40th anniversary "ruby" package and am a little concerned about loosing the stock wheels. What would be a good cost-effective alternative (for maybe street and autox)? Any ideas?
