The ZL1 *is* a 2SS 1LE with a supercharger, more aggressive front aero, and bigger brakes. If you can afford it, what's there to think about?

If you're asking, is the SS 1LE worth it versus a normal SS with regards to track duty competence, that's also a self-answering question, very much YES.

Neither the SS 1LE or ZL1 need anything in particular for even advanced-level track work, just a driver.
