Girl's got a saggy rear end

[rhythmstick]

I was going to say ass, but it may have offended.

Anyway, I've noticed for a while that the gap between the boot and the bumper looked a little big, but thought nothing of it. I have a pretty good eye for things like that. However, I ignored it.
I went to check out the exhaust assembly to see what's required to fit my new one, ( ) only to find that there is a 'considerable' gap between the bottom of the tail lights, and the bumper. By considerable, I'd say about 5mm

Does anyone know what is required to give my girl a butt lift? It's an 03 NB.

PS. I popped my mx5mania cherry today.

Cheers
