Which series is cornering faster than f1? I need non-anecdotal evidence on this one. Also, where did you come up with the idea that gp2 has more down force than f1? We're also seeing peaks well over 3.2g . If you actually look at the numbers, f1 only cornered faster in the 2000-2008 era.
I would request the same and ask you to provide evidence for that claim in bold.
I heard Barrichello say that about the 1997 car on a tv show, once. The 6Gs at Suzuka I read from Mario Theissen:

If you watch ITV's Suzuka 2003 qualifying coverage, Brundle says that McNish(Toyota's Friday driver back then) told him they were reaching 5Gs on the Esses and those are a much slower corners than 130R, done at about 210kmh.
With Pirellis, the highest lateral G-force I saw on a telemetry(they ones FOM display on screen) was 4,5Gs at entry Copse(+280kmh) but that was a peak value and the sustained figure was around 3,8G. In 2010 with Bridgestones, they had peaks of over 5G midcorner(which means a less speed) and sustained of around 4.7G
If you had read my previous posts on the last few pages of this thread, you would know why I claim GP2s to be cornering faster than F1. But I will repeat the reasoning(this time with fixes because GP2 has 612HP and not 500HP as I believed):
Their tyres are the same and also their mass(F1 and GP2, that is). What differs them is the aerodynamics and power.
Renault already admitted on Red Bulletin that their engine generates at least 640HP, IIRC, so they have a max power of 800HP for 35s(and Mercedes probably much more than that). Meanwhile, GP2s have 612HP and no DRS which makes them significantly slower on straights.
100HP accounts for around 3s of laptime gain, on an average circuit. So we can estimate around 6s advantage of F1 cars over GP2s, on power alone(the 35s probably is close to the full throttle time).
GP2 pole this year was 1.29.3, which converted to the same power region as F1 would bring it down to around 1.23.3. However it was done with Soft compound while F1's pole was done on Mediums(gap according to Pirelli between 1.2 to 1.5s), so the GP2 pole now would be at 1.24.8
This is faster than F1's 2014 pole time and I neglected the DRS effect which might account to another second there.
So, on equal power(and tyre compounds) and considering the DRS effect, GP2 pole would comfortably have a lower laptime. And where would that come from if everything else is adjusted to equal levels? Obviously downforce
Also, my comment that current cars can only corner at 3.2Gs comes from the fact that Lewis' 2014 pole had him cornering Campsa(Barcelona's T9) at 210kmh, while Rosberg's 2013 pole was at 245kmh and Webber's 2010 had him flat out at 260kmh.
I know that the RB6 could corner at 5G@260kmh, so, doing the math, current cars would be cornering Campsa at no more than 3,2Gs
