I would have thought "performance" was "standard" in a TC.
For changing the steering rack:
Performance = 15:1 ratio (aka "high-effort").
Standard = 20:1 ratio.
Easy way to check what you've got now (if the old rack is still in the car); turn the wheel all the way in either direction. Make a note of its position. Turn it all the way the other way, counting how many times it turns.
Almost 3 turns = standard.
A bit less than 2 1/2 = performance.
