You should really check up on that, as a sub 9 second run in a Skyline would put you as the fastest at Racing-line.org, and 19 overall in the 4WD category.
You may also want to search the OLR spot races for other threads related.
Mine is 9:004, so close to 8sec.....i think i was one of the first on gtplanet who got that.... but no-one believed me, and everyone one started to tune the R34 ohhwell, now they believe me....this happend a year ago or more. pretty damn tired of GT3, played too much....just waiting for gt4 👍
I actually got 0:09.005 but never took a screenshot of it.
I would have kept trying for an eight, but GT4 came out and i haven't touched GT3 since then.
