I'm sure you already are on top of it but just keep in mind several reasons guys choose wheels... I'd say looks is the first thing out the gate for most peops, but then you've got offset, wheel size, wheel width etc... The TRD's are one of the few 17's(From what I have read, I am planning on test fitting some 17 inch Methods to see if they will fit over the brakes) that you can fit on the 200. And they are a 17x8 with a 50mm offset, so they stick out only slightly farther than the stock wheel. So what the TRD wheel gives you is more sidewall a slightly more aggressive stance but something that does not stick out so far that you still get a good "tuck" with a 35 inch tire. The Ausie's run a lot of the Methods with a 25mm offset(18x9) and roll 35's(just a bit tighter than the TRD's). With an 18x9 with 20mm offset things start to get a bit tighter, that extra 5mm of offset starts to put you in danger of the tire hitting the upper fender lip at full tuck(depending on tire width/height) I do think the added wheel track and stance of the 20mm wheel looks awesome, but just keep in mind there are also drawbacks(IMO). I'm thinking of getting another pair of shoes, would proly be the BFG AT's. I would proly roll them for the street and snow only and thus could roll 35's with 20mm offset wheels. Then I'll grab some Methods (25mm offset) and slap my mudders on those for offroad to give myself a little more "tuckability"...
@montanarally is rolling some 12.5 inch wide tires(34x12.50) on the Anza 18x9's(he is going to take it out and flex it up and will have some nice feedback to add to this) hope this all helps, just wanted you to keep in mind all the factors that go into choosing a wheel.... -Kreiten
