2'06's should be possible
ARGGGH.
Despite RPM_crx's pimping of the GT-R, I would like to stress that it is not a good car for this race.
Is it impressive? Uh, sure; plenty impressive for a 1500kg car on S2s.
Suzuka has more corners than straights, and racing a car that's at least reasonably fast in the corners is the path to the fastest lap time.
A low-grip 1500 kilo car
sans aero cannot be fast in the corners. Its just not physically possible. The only reason the GT-R can even create decent times is because it's straight-line speed is set to "insano" to meet PP.
A wide, hard to pass, slow in the corners, blazing in the straights car spells
disaster for non-RBE races. Think about that for a second.
Say a GT-R gets out in front at race start. Everybody will pile up behind in the S curves, the GT-R's girth stifling passing. Same for Degner and the hairpin, and once the GT-R hits 200R, its gone. You could slingshot around Spoon and catchup on the back stretch, but you can't carry that momentum through 130R; the GT-R has to slow way down to take it, bunching everybody up through Casio, only to have the GT-R leave you in its wake again on the straight. Bad times.
Unfortunately, the same situation applies to anyone who improperly tunes their car. I beseech you guys to not think of S2 tires as a free pass to crank up HP, but a challenge to scrape out as much grip as possible.
AWD is not the answer to S2s. Light weight and aero is.
Lotus Elise tuned, 2'06.6 (roughly tuned, with suspension straight from 750PP suzuka)
Have at it.
