If you really want some suggestion I would say "Silk Cut" font on the side should be quite bigger, you know... even to bent over on top over the chassis curve. It could be, I would say, even 200% of this one as it now.
Otherwise... maybe some sponsors more, maybe even one instead of those lines behind cockpit or leave lines and then put some sponsor over them.
Cars almost always look better with more sponsors, aren't they? =)
But those are just some of my ideas, car look good in this state too. ;)
