I think the advantage on track condition , is 100-180km acceleration, other benefit is more option to choose gear in corner cause even +1 higher gear have power .

If there is any advantage it should be in 0-100km/h (62mph) as both setups need to upshift twice. 100-180 km/h, or 62-111mph, with 5.1 gears you have to upshift to 4th almost immediately, whereas stock you don't have to until 84mph, but by then 5.1 has to upshift to 5th. At 106 mph, stock upshifts to 5th and 5.1 upshifts to 6th. Overall, more upshifts with 5.1 gears, and similar overall gearing from 67mph on up, my money goes with stock 4.1.
You don't have more options to choose gears in corner. Actually, fewer...
OP, if you want to know the effect of changing to 5.1 gears at just about any speed, just drop down a transmission gear. If you can't, then know that at that speed you'd most likely have to be in a higher transmission gear with 5.1.
I'll say it again, if it's not 0-XX acceleration you're interested in, but just want more oomph in general that you think diff gears will get you, just wind out the engine more and delay upshifting with stock diff and get the same effect for free.
