The BMW shape doesn't allow for numbers on the windows which is where they are on V8s, each car actually uses the same texture for the windows. That's why the top stripe on the front and rear windscreens are V8 logos, rather than the 'Norton360' as it should be on the Triple8. The Norton strip is actually on the roof.
In any case, that particular set was just me playing around. Fingers crossed we might have some proper shapes soon and if I get my skates on, maybe just maybe a full set for release for Xmas.
