Has anyone fitted the rear spoiler from powerfuluk . I wondered if it would help to keep the back of the Fatty cleaner. 2007 Vogue TDV8 in Zermatt Silver with Charcoal

I have had an Overfinch one fitted... it looks good in my book, but it doesn’t seem to keep the rear screen any cleaner I am afraid.

I cut large slots with little scoops on the trailing edges in a spare spoiler which made a slight improvement but not enough to call a success at stopping the rear-end from being covered in dust.

I'll forget that idea then.

I don’t know but I would hazard a guess that it’s physics me thinks...large object (FF RR) traveling at speed 😉 punches a hole through the air and creates a reasonably big vaccume immediately behind, sucking any airborne muck onto the rear of said object.... Current:
