Umm... Silly question, what is 'SGTI'? Is it satria gti? If it is, then there might be the question what eng was he using? If its stock gti 1.8 eng without any form of forced induction, then maybe a bit far fetched dont u think to touch 210 at the front straight? But then again, if its a souped up evo or vr4 motor, then its different.
A fren was driving his putra in the tracks sumtime ago, it was setup as a drag machine actually started braking at the 250m marker and his speed was >225kmh.. Now, if he had setup the car for tracks, he wud be able to brake at the 150 or 100 marker. the speed shud be higher. As for the sgti ( if its a satria gti..) If its modded, then it cud reach speeds higher than a gt3 on the front straight. :)
