To make a long story short i have a z28 and a friend of mine has a 94 v6. I ordered the pro kit, well they sent the wrong one are going to let me try them on my car and if i dont like them they will sell them to me for next to nothing because it was special ordered and has been taking up space for a while. if i dont like these and still want to go with the pro kit would they work on the v6. I am sure the spring rates in the front are probably different but would these still lower it?
