Anyone Successfully Reach 276mph Legitly?

My setup is the Bugatti EB110 SS obviously, no front splitter, narrowest tires front and back, no cage, lightest wheels, etc. Basically everything I can think of to get it to go faster including stock tires, they’re slipperier so technically that’s less resistance. My Record is 275.9mph, and I cannot for the life of me break that 276mph barrier. Any Tips? The road I’m using is on the freeway, start at the bottom of the map and speed up and over the hill on the bridge. I can peak 273 up the bridge and 275 down, which is kind of weird since i can get the RUF RGT8 to 259mph up the hill and 264mph down the hill. Any tips are appreciated.

Reduce weight more maybe?

already as low as it will go without removing horsepower ie: oil cooler etc.

Well than I don’t know. I think I might have a while ago but id have to go check.
