I bought a Brawler too. Fun car, but the brakes are pretty awful. You have to feather them, or use the handbrake to swing the rear end around and get on the gas, like a rally car.
I went a little different with mine. Lowered the suspension and used street tires. I also gave it a brushed gold paintjob, since R* was giving those out for free over the past weekend. I'll probably respray it someday, but for now I kinda like it.
