I ordered them from Money Maker Racing.He advertises on Racingjunk.com ,they were 369.00.Where did you get them and how much were they?The Cal -tracs are fantastic! I set them up as per their instructions and actually had to back them off some.They were making the car bogg off the line.My re-action time went from so-so to really good.I can't wait to throw some more HP at them.You do pick up a little more road noise.How much of a difference did the tracs make?
