Thanks for the welcome everyone!
The wheels are 20 x9 with a +40 offset. They are sold in New Zealand as a BGW Storm, but I'm pretty sure they must be sourced from the US, possibly under some other name. I have been searching for the last 6 months for something that fits the Journey ( and doesn't look like a disc out of a food processor ). Every decent 5-spoke rim I found on Ebay suddenly went out of production when I ordered it, or in the case of the last set, despite the seller quoting it as a definite fitment for a '14 Journey, fouled up on the front caliper. That was after paying $120 shipping per wheel to get them here from the States.
So, anyways, I had the front face of the wheels painted to match the stripes , as they were supplied in a matt gunmetal finish. Tires are Falken 245/45/20, which are exactly the same height as the original 19s.
I fitted a set of H & R springs - same deal again - advertised on Ebay as fitting '09 thru '14, but the rear coils don't fit the later Journeys. After spending the best part of 2 hours gutting the interior to get at the top mounts for the rear springs and finding they didn't fit, I wasn't about to put it all back together without some kind of result, so ended up cutting one coil off the original springs and re-installing. Springs are still captive, and the front and rear fender to tire gaps are now spot on. The front ones fitted up nice right out of the box.
I made up and fitted the striping myself (I'm a sign guy by day). The stripes run fully from front to back, right over the roof which was a bit of a mission, but well worth the effort!
As for the headlights missing the amber reflectors, that is how they came as stock. I guess the 'export' models must have a different light to the US version. Most of the stuff we get over here now has clear lenses but with amber bulbs where necessary. An easy retro-fit for you guys wanting a clear lens, although we are right hand drive so our lights dip the opposite way - I'm not sure whether that is a function of the lens or the bulb?
