i wonder can we make any changes to our gear ratio?
as currently my 1.8(M) is making 100km/h @ 3k rpm 5th gear....
seems a little short.....
it would be better if can achieve 120 or above.....
What are everyone's thoughts regarding chassis strengthening? Would you say that your Skyline already is perfect from factory meaning its not too stiff that road use is unbearable yet able to handle any extra power...
