im doing about an hour in each car round instanbul, and when i make a time faster than a sim bin setup on lacetti, i'll tweak the lacetti, beat the alpha time, then try again. i still got a few seconds to make before the number 1 spot on the lap downloads.
toe in advice seems to be working, quite surprised how much coast diff came on your setup (70%) i was running 40%/50%/5 on my setups which i found a good general setting. yours does seem good though. my anti roll bar i was running was very close to yours, switching to yours i noticed very slight gain.
i noticed something though, i seem to drive the alpha better when it has a few laps of fuel in. strange that, maybe it affects the balance to rear?.
tried 50/50 brakes, seems good, will need to test that on a 12 lap race tho, see what the wear is like, im locking 1 rear all the time. i did run R30/F70 before, because the tail was coming round as im a really late braker, in fact im normally enterring fastest i can and braking right into the apex for nearly all turns, or im braking very early for a fast exit to a straight. thats why im concerned about the rear wear. just in case the side that isnt locking doesnt have grip after a few laps.
update: grrr, i jump in lacetti, 6 laps of consistent 0.500 second improvements until ... 1.2 seconds faster than my alpha,... this aint fair
i stop driving the lacetti for a moment to save the alphas face. in the alpha each lap my times all seem to be within a very consistent 0.01 seconds of each other, im just not finding those whole seconds and not improving anymore!. The setup you gave out Bram is a little better than mine tho, managed about half a second faster consistently. that lacetti seems to just stick to the road like glue in comparison, and i aint even tweaked it yet.
