TT Skyline R33 Deep ForestOpen

[bacens]

Hi everyone
I' ve been reading this forum for quite long and I must say I've learnt a lot, yet this is my first post.
The thing is that Gran Turismo to me means SKYLINE especially r33. That was my favorite car since GT1.I'm not a great racer or a great tuner but this car is my "love". Recently I started testing my racing skills on Deep Forest track. Just wonder how much do I stay behind the best drivers and how much do I need to improve to be a little bit more competitive.
