This is my first post here and found this a subject that I'm interested in because I am thinking about upgrading to caltracs due to excessive wheel spin that I'm experiencing. You mentioned that caltracs do not do well when used with SS springs. I'm wondering in a car like mine that only launches at around 400 foot pounds of torque and reaches 450 foot pounds at 3750rpm (approximate lockup of torque converter) if they'd work with OK with SS springs in my setup which is mostly on the street.
Also do the caltrac spring set up function OK on the street?
