jz: thanks bro. as for the shifting, i mentioned i had messed up tyres, i stay at redline for that reason, if i shift instantly before redline its not much of a perfect shift as i lose power due to wheelspin which is why i let it cutoff..

the above video clip is when i dragged against a manual r18 '2006 civic when i didnt have my stage-2 cam and engine head. result was a win by 4-5 cars. this video shows me overtaking at around 120 or so.. the other video below wasnt so clear but shows me overtaking at launch.. from a roll-on there was a gap of around 6 cars.

sorry for the poor video quality, it was some guy in the car behind me who took the video..
