Spent the afternoon fighting to get the diffuser on the rear bumper, no it doesn't do a lot but I think it looks smart and was on the blue car so was there to be used again.
When we were in Germany this year Dave noticed how it flapped about a bit so I came up with a quick fix to try and keep things less flappy...
If my OCD kicks in I might get some black cable ties in the future but for the time being its out of sight so I'm not bothered by them at the moment.
All I need now is someone to follow behind me and check on how flappy (or not) things are.
