What year? 88 and later?
The reason I ask is they are not available for 84-87. Well, technically they are not available, but, if you want to spend the money Koni will build you a set...

they're good 
I have them on my 92 and use them for autocrossing. Front adjustment is easy as pie but it's a little more complicated to adjust the rears... you either need to unbolt the shock or drill a hole so they can be adjusted from the top.

My 88 Z51 Vette had the Koni Yellow Sports on it when I bught it. The center rod is physically bigger than the stock units making it pohysically stronger as well as valved MUCH firmer. The minimum firmness level on the Konis is greater than the maximum level of the stock units.
I used mine on the street for thousands of miles and it was really too harsh with the 88 Z51 springs. Finally I bought some new replacement Z51 Bilsteins. Much better on the street without giving up handling. If you are going to use them for autocross, I think you will be very happy with them. As mentioned, the fronts are a piece of cake to adjust, but the rears require unbolting. It isn't a lot of work, but not nearly as easy as the fronts.
The 88 had a different length front shock than all the other C4s. For an 88 you would need the 88 specific fronts and the 89-96 rears. For 89-96 the Koni Yellow shocks are all the same.
