Daily driving, spirited driving (no track) and traffic jams? - 19 row cooler recommended

All the above plus track usage - 34 row oil cooler needed

Mandatory things to get done to the Z once in you possession unless done so already (in terms of importance):

1) Wheel lock removal
2) CSC elimination kit (Z1 or Z speed)
3) Oil cooler (Get one with Setrab core, check out Z1, Stillen, Zspeed or Fast intentions)
4) Differential bushing change (White line or SPL)
