Ferrari TR, this is more like an exercise/practice for me, so even if i make mistake or mess up, it is barely visible
pics are download from the internet:
NEW BOTTLE
OLD BOTTLE
both are different in colors, the one shown on the spoon are NEW, old one look something like this:

(it look brownish)
73superduty, yeap i airbrush it
cjsbosox, the front splitter is 0.5mm or 0.0196inch, unfortunately i can't find a thicker rear tire, the stock tire are thick but too narrow
Tompidom, the 1/48 CF is from scalemotorsport, i'm worried the 1/24 CF pattern might appear huge on the tiny dashboard

but i'll test first & see which is better, also i see that you are also doing a 599, maybe you can try on it first & show us how it looks
