I have had this for about 3 years now, and keep forgetting to post it for sale. I just want it gone really. I measured the spring rates about a year and a half ago, and they are infact JUN springs, but are in a Skunk2 box. They come with ITR valve retainers, and JUN vave key locks. They were used for a short time in a car that was built by Factory 5, which is now Profunction. JUN Specs can be found here: JUN RACING VALVE SPRING i am asking only $200 plus shipping!
