We can't tell you what settings would be correct without knowing how much light is arriving from your lamps at the subject. For that you will need an Incident Light Meter. Incident light meters are valuable because they do not need any compensation for light-toned or dark-toned subjects. They do not read the light reflected at all... they read the light that's "incident."

I wonder as a first test how the OP would get on if he metered off the track, and used those settings in manual mode.

Yes, metering from the track as a grey card target occured to me, too. Notwithstanding that the images have been brightened in post, I think it may be a little too light...

... but, even so, it would have been better than metering from the white of the cars and getting more severe underexposure.

Final Hint: The histogram is your final arbiter as to whether the exposure you have is correct. The lightest tones should just kiss against the rightmost limit. They should NOT be bursting through it, and there should not be a gap.

(In your sample shots the histo is rising as it meets the right limit... that is called "bursting through." It should be falling as it reaches the right limit.....

..... ideally with the histo slope exactly splitting the right angle between the bottom and the right vertical.

An additional point on this is to also look at the RGB histogram and make sure that none, and in particular, the Red channel doesn't burst through.
