Help with tuning for top speed

I’m busy tuning a car for top speed [Agera], but I can’t manage to push it to 270mph. It currently sits at 269.3mph, and I have no idea where to go from here.

I’m not really the person to ask when it comes to tuning, but I’ve tried to adjust everything. I did another run through of the Tune setup and managed to get another .2 mph by making the springs on both ends of the car as soft as possible, though I haven’t applied it yet.

So does anyone have any ideas as to making this go slightly faster. Like I said, I don’t really know much about tuning, but I’ve tried to find the best setting for every section.
I also have Drag tires instead of the normal high end tires. I assumed Drag tires would be an improvement over the other set.

Depending on how much pi u have left race tires won’t affect speed just more grip thru corners. If its just for drag then stay with ur drag tires.Higher psi in ur tires will improve speed slightly. Also raising the front spring height above the rear will improve top speed (I think but it could be the other way).

If ur strictly looking for drag setups though my suggestions may not work for you. This is what I would do for race cars on Lemans not on the strip
