If you have a PS2, you prolly have bought GT4.
If you have bought GT4, you prolly have unlocked 240ZG.
If you have unlocked 240ZG, you prolly have three of them, one color each.
If you have those 240ZG's, you prolly have done maximum upgrade and weight reduction.
However, power is not enough, I am looking for a good tuning spec.
Care to share yours?
Thanks
