Saw a post with black Testarossa on 9gag and it looked awesome. Checked to see, if the Testarossa by a3dr had a black paintjob, and it did, but it just wasn't black enough 
I changed the paint to a flat black instead of metallic, painted the rims and calipers black, tinted the windows black (the default ones were bluish green), even replaced the number plate and badges to black ones
Update 1.2
The mod was recently updated and the S1 version (now called Canyon Spec) has different rims now, which didn't work with the skin. I repainted the new rims and calipers black (I couldn't repaint the chrome part of the rims) and split the 2 liveries, since the standart spec still uses the old rims
