If you tune a car for a specific PP-limit, you got the option to either go with more weight and more power or less of both. The PP-Formula should balance that out and at least if you compare different levels of power/weight for the same car, this worked quite well in the past. There were of course minor differences in performance depending on car and track, but generally the performance difference was very little at a given PP. The tradeoff was usually between higher topspeed (heavier and more powerful car) vs. shorter brake-distance and more nimbleness into the corners (lighter and less powerful car). From my recent observations with a McLaren MP4-12C this old balance, that worked well through GT5 and the first the patches of GT6, seems broken now. I don't know exactly since when because I didn't test everything for every patch.. From the Ascari TT and following tests in online races (I chose the Red Bull Ring because I raced it a lot recently) I got the impression, less weight and less power is generally better now and by a lot. At Ascari I gained ~ 1sec just by going from stock weight to minimum weight and reducing power accordingly (setup otherwise just the same). At Red Bull Ring I gained 0,8 sec on my personal best (from 1.31,6 to 1.30,8; 550ss, online race with wear). Friends of mine (who discovered it before me, making me wonder how they got so quick suddenly) agree: low weight is the way to go now. Back in the day the tradeoff was balanced, so where is this unbalance coming from? So far I think the gain is mostly from accelerating out of traction limited slow corners. Back in the day there wasn't a difference here. The heavier and more powerful car had more power to bring down, but the more weight also gave better traction, canceling the disadvantage out. This seems no longer the case. In the lighter car you can now be on throttle much earlier and (at least at 550 sh/ss) don't have to worry much about throttle control. The difference seems especially noticeable if the rear (MR-car) has some lateral load out of the corner, so lateral forces and the longitudinal force of acceleration have to "fight" for the limited grip of the tyre. My guess is the recent physics tweaks changed something about how weight pushes the rear out laterally from movement momentum and at the same time increases the pressure on the tyre, giving more grip. So I think, as a reaction to the physics change, PD needs to change the PP-Formula, increasing the power per kg of weight slightly to get things in balance again. So what I'd like to know from you: 1. Do you agree (for other cars as well) lower weight and lower power is quicker now at a given PP? And from what car are your conclusions? 2. Do you agree it needs a fix at the PP-Formula (if the physics remain as they are now)?
