About the Tsukuba laptime:
The video above shows 1:04.67.
This video claims that the fastest EVO VIII MR does 1:04.50 (sadly it doesn't mention that the GSR, RS 5MT or the RS 6MT did that):
This page shows 1:04:15:
http://www.fastestlaps.com/models/mitsubishi-lancer-evo-viii-rs (it shows a non-MR EVO VIII RS 5MT with wrong datas).
The previous video (which claims that the fastest EVO VIII MR did 1:04.50 at Tsukuba) claims that the fastest EVO VIII (non-MR) did 1:05.12 at Tsukuba. Is there any reference for the 1:04:15? Is it on YouTube?
