What is this older racing simulator called?

I remember playing this racing simulator on the PC somewhere around 2009-2011 where the cars had real physics and even tires physics and heat simulation in regards to traction.
The cars in the game were older vehicles from the 1980s or so and one of them was a 198-something RX-7 that looked like this:
The other car was a hatchback Honda Civic which was again a 198-something year like this:

These were the only two cars available because you had to buy the other I believe.
The name that keeps popping into my head is Project X racing simulator but it's honestly just a guess.
This game was VERY low graphics requirements and I was able to run it on this:

I did add 1GB of RAM to this computer though just fyi.

Added (1). I forgot to mention that in the game you had to actually start the car, hit a button to turn key, and you could use the clutch just like IRL like if you let it go too fast it stalls. There was an option for setting the keyboard keys as up shift and down shift and for the clutch.
You could also move your head around the interior of the car and roll down the windows, turn on the headlights, etc. I just found another game that might be it called Rfactor.

Added (2). I found the name of the game! It's called Live for speed… Lol I would never have guessed since it's close in name to Need for speed.
