The snowflakes would look great no doubt but there are a lot of late 2d gen ponchos starting to use them. I would stay with the multi-spoke design but I would lean towards the Boze pro-touring wheels in 18" just to be a bit different.
I'm not one to talk though as I went with Coy c5s on my 81Z because I like the looks of TT CL205s which look very similar.
Either way the snowflake/pro-touring/mesh type wheels look bitchen on firebirds and T/As.
