just my ears constantly popping.
id think my turbo wasnt spooling or something til i swallowed.
cars ran just fine though.

main problems with my car were tires, shitty brake pads, and i think the biggest was the seat. i spent most of m time fighting to stay planted, and i have a bruise on my hip from it.
before i go back i want better brake pads, better compund maybe wider tires, but number one is a seat.
