Speed isn't everything, its the only thing! From what I've seen tires and drivetrain give the same increases in speed. While drivetrain increases acceleration at the same time, it doesn't mean much if you can't negotiate the curves. But at the the place you are now 2 engines on tires to get to 9 will give you more speed than 2 tires on drivetrain to get you to 5. And your upgrades should stay with the car.
