I'm an SCCA Solo 2 National Championship Trophy Winner, and multiple regional carting championship winner. Still want to tell me I've never been in a real competitive wheel to wheel environment and that I don't know what I'm talking about with respect to tire performance?
I've driven competitively on a very wide range of tires, from crappy all-seasons, to performance streets like Dunlop Direzza StarSpec Z1, REO1R/RE11 as well as DOT R compound Hoosier A6/R6 and V710.
I agree with everything else you say, the top drivers will rise to the top. The point is the level of difficulty in GT5 associated with driving the tires to the limit. The racing softs are wayyy easier to drive fast than the others. The grip level you achieve with them is ungodly, something like sutained 1.5 g's or something like that (mechanical grip only, less than 60mph range we'll say, no aero impact), which for any OEM street car in real life just isn't going to happen!
As a point of reference, my real life s2000, competing in SCCA B-Stock class, with tuned shocks on 245 Hoosier A6's sustains somewhere in the 1.13 G range (sure there are spikes of much more than that, but were talking sustained lateral grip).
I'm just all for keeping the driving skill placed at a premium. You achieve this by running less grippy, more "real world" tires where more precise braking, steering and throttle input is required to hustle the car around the corner. This is why things like GT-Academy run such tires to weed out the good drivers. Understand the "debate" now?
Anyway, look forward to racing with you 👍
