For track use you'll need Cusco front camber arms & aim for around -3.5 degrees
And LSD, 1.5way & ensure the lock isnt too mean.
Oil cooler is a must & bigger radiator (Koyo, not china spec).
Brakes, go for Ksport 330mm 8 pot kit & DS3000 pards all around.
Proper bucket seat & harness to hold you in place.
Then you are ready for some action! Until the turbo lets go then go GTX 3076, injectors and Z32 AFM & say hello to 250-300rwKw (petrol to E85)
And then and then and then and then... I love track days!!!
