I have pulled this harbor freight trailer for thousands of miles, this was Miller Motorsport Park in Utah, about 1,300 miles round trip from home.

I bolt on lights as needed, no heater, for that I wear really warm clothes and try to not breathe towards the windshield, no air, for that I wear my cool shirt, no wipers, I use rain x, no signal lights, I use hand signals, the side windows are attached to a strap so I can remove them easily (8 lbs each). I try very hard to not get pulled over, how ever I have been pulled over more than once, just because the officers liked the car and wanted to check it out, fined once at Infineon when I went out to the store for somebodies cigarettes. Pulling the trailer and sometimes going fast, I get 20+ mpg. Suburban gets about half of that at half the speed.

You might have an over heating issue on track with the a/c coil in front of your radiator. This isn't my daily driver, it's how I bought the car, I would probably keep those things in that you are, except the A/C, if you find over heating to be an issue.

I am at 2600, but I got there by having the least amount of fuel that the car will run on, which is about 2 gallons or it will starve in right hand turns, also with worn out tires, so technically I can not be DQ'd for weight unless the official scales are different than mine, so if you are close to 2600, you should weigh your car with the official scales at each race weekend before qualifying or a race. I usually finish races around 2620 because of tires not being worn and maybe a little extra fuel. I have finished at 2600 even!
