Caltracks VS Super Stock Springs

Ken love your Demon and it runs awesome ! You might know a friend of mine who runs a Duster in G/SA and E also I believe. He has a sweet Duster that has dipped in the 10's. His name is Mark Dickerson. In fact I have a suregrip in my sons 8-3/4 rear in his Dart that mark gave me.
As for the Cal tracks I hear alot of good about them but I agree with Ken as the SS springs have always worked great for me and is more then enough to get your car to work good. I plan to get a set of SS springs for my 63 but it has pulled a 1.58 best 60 on the original 44 year old leaf sprigs and air shocks ! And when it hooks hard it gets air under the left front wheel. So I cant complain for a mid 11 car hooking pretty good on 44 year old springs. But for very fast 9 and 10 second cars I see many running Caltracks and hooking real good also. Ron
