Andrew,
The rims that are in the photo are a D3 19" rim.
(6 Spoke are a 19" Rim only & From the V8 HSE) (5 Spoke are an 18" Rim only & From the Diesel 2.7TDV6 SE)
I had the same set on my D4. I know mine is a 2.7 but they WILL fit a 3.0.
I know as a friend tried them onto his D4 & then purchased them from me.
Same offset & all. They are also the spare on the LS sports fitted with 20's as the spare is a 19.
Cheers
