Can you share a little more about what you want to do?
Are you just planning to go play with the car, or are you interested in being competitive? Is there a rule set involved with restrictions on allowed modifications?
In general, I have found "Cup Kit" packages to be designed for looks, and not optimal for performance. Of course most coilover kits are the same way - though they have more flexibility to make them work better with different springs.
Not knowing the goals, or your car, a good basic starting point for an occasional play suspension would be a set of springs that do not lower the car very much, with rates that are high relative to stock or typical lowering springs and Bilstein or Koni shocks with an larger rear anti-roll bar.
Also consider asking in the autocross sub forum here.


I am also redoing all of the necessary components to refresh my suspension.
