The 48 used to be the master of getting the rear of the car to drop the splitter out of the air on the straight, and pop back up under braking. The zero ride height seems to have taken that away, and maybe they are leaning on tire pressures too much.
Yeah, I think that 0 Ride Height obliterated that, but I wonder if it's coming back in a way. Makar was talking about teams lifting the splitter in their tuning trends. JGR has been fairly quick all year in short runs. They have some poles, but were getting annihilated in the race. Here's my thought.....They started slammed, and as the fuel burned, the car lifted, and totally screwed an already tempermental aero platform. The adjustment was to manage that "lift" better. Penske has nailed that in the short and long runs, but they are probably more vulnerable in the short runs. Dallenbach made the point on one of the TNT broadcasts that horsepower can compensate for some of the aero deficiencies. Again, I cannot wait to see what happens when we get the Penskes turning the corner at Indy, and the Hendrick boys hauling ass down the straights. With the recent progress, not sure where my TRD Toyotas will be. There is confidence in our camp which gives me hope, but this has notoriously been a difficult place for Toyota.
As for the tires.......It was my understanding that originally the 0 Ride Height was going to put the suspension back into the suspension instead of shocks and springs only there to create an aero platform. When the suspension serves only this purpose the tire becomes a tunable suspension member. It was not designed for that. I do believe that Penske and Hendrick have been extremely aggressive with pressures while the TRD Toyotas have been very conservative. I think that the Penskes and Hendricks have backed off--they found the line. The TRD Toyotas have been very, very, very reluctant to mess with the pressures. Interesting and a part of the sport I really enjoy.
