[ultra]

Hm. Before we get overly serious let's not forget that the ideal set up will depend a lot on the use case for the car - street only, street and occasional track, track and street or track only.

Finding the sweet spot(s) along the modification continuum between OEM and all out track setups while maintaining the playful nature of the car will be the interesting part. If all that mattered were speed this would be the last car I'd have ever considered!

I don't mean to be negative but I don't think that building an 'ultimate track' setup will be very challenging at all.

It's pretty much the same old formula for every car out there:

High end coil overs + adjustable top hats & bolts + poly bushings + sways & adjustable links + strip it out as much as you dare + cram as much purple crack into the wheel wells as you can & you're done. The crazier/richer guys will go with FI setups, carbon bits and perhaps aero.

Much like they said in Battlestar Galactica, all this has happened before and it will all happen again.

So, if it's tires we're talking about then I'd suggest AD08s or RE11s for versatility, resilience and performance.

Track only tires - Hoosier R6s, Hankooks, BFG R1s, whatever. They'll all stick something fierce if dedicated track tires are your thing. NT-01s if those are too hard core.
