Are all Right Hand Drive Prius the same mechanically?

I drive a RHD Australia-delivered ZVW30 Prius built in May 2009 in Japan. I'm considering ordering some Prius parts from Japan via an agent in Australia who imports high-performance parts for grey import second-hand sports cars.

It seems that LHD Prii have some mechanical differences in suspension etc, possibly by virtue of being built in USA and using certain local components... like floor mats and accelerator pedals

I feel confident that a sway bar, strut brace and suspension I purchase from Japan will fit an Australia-delivered car built in Japan. Does anyone have any experience of fitting Japanese parts to a RHD Prius?

Yes, there are a lot of differences in trim levels and technology inside the cars for each market. But are there any external mechanical differences across RHD Prius?

 

@Grumpy it's Gen III. I unintentionally upset our American hosts by calling it a 2009 model. Because every reference to its build, compliance with Australian Design Rules (ADR) and first registration were in mid-2009 I have trouble referring to it as the 2010.
@Jimbo I couldn't confirm the factories. I wasn't about Wikipedia; China isn't mentioned and Thailand was marked "citation needed". Mine was built in C25 Tsutsumi plant.

 

@ xs650 That's interesting. Stiffer springs would make sense because Australia roads aren't so good outside of the cities and we prefer a firm ride. A bit of a change from my Citroën I can tell you!

But I can't see any difference in ground clearance because the heights are the same in Japan and Australia specs.

I can't confirm the ground clearance as toyota.com.au doesn't show it. I measured 185mm at the sill of my base Gen 3, but there's some gubbins that might be 20mm lower than that under the car.
My Japanese Prius reference shows ground clearance of 140mm.

The heights of the new 2012 Prii in Australia are 1490mm for the base on 15" wheels but 1505mm for the i-Tech on 17" because it has the moonroof. This matches the Japanese specs. So the wheel size has no impact on the height, which presumably means no difference on ground clearance. toyota.jp Æ’vÆ’Å Æ’EÆ’X Âb Æ’XÆ’yÆ’bÆ’N Âb Ââ€Å’³•\

I was in Japan when the accelerator pedal/floor mat story broke. The overwhelming theme from the Japanese media was that whatever faults there might be it smacked of a beat up to defend the American car industry... despite the fact the many of the issues were in Toyota and Lexus cars build in American factories. Toyota didn't help by appearing to withhold information, but the reaction was way OTT. The Australian automotive media reminded its readers that every recent Australian-built car had been subject to recalls and service advisories at least as serious and perhaps more numerous than Toyota.

Oh, and as for "3rd world suspension", I happened to be reading a review in Wheels magazine yesterday that said, "Volvo had inadvertently supplied 3 vehicles for the test day with a much softer suspension tune, not the firm European suspension that will be on the Australian-delivered models." Guess who likes it soft.

I didn't mean for this to descend into a Right v. Left battle (did you see what I did there?) but it always seems to happen on these Internet things.

 

@Grumpy you asked what plans? A strut brace and rear sway bar to start. I might get a chassis stiffener too.
Grey imports of Japanese cars are very popular in Australia. Perversely, the Australian emissions rules generally mean that only the turbo variants get in.
So there are a lot of importers of Japanese tuning parts in Australia. Want parts for a 1981 Soarer? No problem. Can't find "Prius" on the drop-down list? Well, of course.
I found an importer who is happy to source Prius parts from the brands they import. And since they import by the container, a bulky body kit doesn't cost $10000 in postage stamps. I have to use a Japanese Prius tuning and style magazine to find the brands and the Japanese websites to find the part numbers, then I can order the parts. Clunky, but it should work.
