Do they keep the sway bar? It seems many Viking front offerings do not and there is no mention of it in the description. On the Viking site it is an additional cost. They seem to be oriented more or for the strip, which is fine as long as they also perform well on twisty back roads with adjustment. My main difficulty is that I want a setup that hooks and I also want it to not feel like the fat pig it is in the twisties. My last car was an easy choice as I stayed N/A and I wanted handling. The choices were also limited at the time. SP083s and Steeda adjustables felt pretty good but ended up lower than desired. Now with an Edelbrock tvs an occasional trip to the strip will be in the cards but I like a firm sharp setup most of the time. I'm open to other options as well. I have considered Bilsteins as well but they seem valved for the softish stock springs.
Not sure, I assume so since they are stock type struts. As far as street use, don't know that either. Mine is mainly a street car, but I am not interested in twisties. I'll report back when I get them. Currently says late Q3 early 4. Nothing is ever on time though.
