    Absolutely Bill. Tires and wheels are on order from Discount Tire and they have a local store in my city. I'm having everything installed on Saturday and will report back with feedback and multiple photos from different angles! I see lowering springs in my future and will have another dilemma deciding on which ones to get. It's a never ending battle! ;)

    I went with the machined face version. Snagged the photo in a post that SoCalBPrius made in the aftermarket wheel section.

    Alright all you FRS wheel fans. I'm going to include a few pics with notes. Hopefully I format it correctly. I ordered the spacers from motorsport-tech.com. They are 3mm spacers that fit the 54.1mm hub. They step up to a 56.1mm hub for the new wheels. They are hub-centric to the original hub and that centricity is carried to the new 56.1 dimension. They are made out of Alcoa 6061 t6 billet aluminum. The new 56.1mm hub portion protrudes 10mm so it will positively engage the new wheel (I made sure the protrusion was tall enough because the FRS wheel, and many others, have a taper for the first few mm's of the hole. I spoke to the owner, Leonard, and he said they would machine them today for me and mail them so I would have them by Friday. Cost was $140. More than most generic spacers but they are made in Sparks, Nevada and it was nice to call and talk to the person who knows what I want and how to answer questions.

    OK here we go. First pic below. To answer a question from a previous poster about pad wear and the possibility of the caliper touching when new pads are installed. This shouldn't be an issue. You can see the contact marks on the first picture......this is from the caliper mount (shown in second pic) which is fixed. This is the object that the new spacers are needed to clear. With the new spacers it leaves us with 2mm clearance. The caliper itself, the only part that floats in and out, is further from the center point of the wheel and as such is further into the arc of the spokes which leaves tons of room. The third pic shows me pointing the portion of the spoke that the caliper is lined up with. The spoke arcs out drastically here which leaves lots of clearance.

    Hope some of this helps. I will have the spacers on Friday hopefully and will install them. I'll post pics with results shortly after. I thought about going to a 4mm spacer but with the 3mm I am already losing a few threads for the lug nuts to engage. With the 3mm spacer I am still getting 6 turns of engagement which is a word of mouth industry minimum standard.....I feel more than comfortable with that. Going to the 4mm would drop you to around 5 turns for the lug nuts......still probably ok but if the 3mm works fine then why bother.

    Wow, Great! Looking forward to your final post. Can you send close ups of the adapters?
    I still have questions about what lug nuts to use and spending $220 on new TMP's and what it takes to program them. Or just go with the black tape method of dealing with the TPM warning light......

    You also have the option of using the TPMS from your oem tires. Alternatively, most tire shops sell generic TPMS, which will work with the Prius, for a fraction of what the OEMs.

    I will send pics of the adapters and the final assembly. I'm going to take my TPMS sensors out of my old wheels and put them in the new ones this weekend as well. Its a fairly simple job to do even if you don't have a tire machine to break the outer bead. Some beads are hard to break and if I run across one of these I just jack up one corner of my truck and slide the wheel under just enough to cover the sidewall only and slowly lower the truck down until the bead pops off. Remove the sensor and install in the new wheel assembly and air it up.

    Thanks for posting the pics and update with your spacers. This should help a lot of folks. :)

    I just bought generic 3mm spacers and put them on, no wobbles or anything

    Firemech,

    I just bought the exact same wheel/tire set as you! (Some comments on these summer tires say they are lucky to get 20k miles out of them.) Good! , soft sticky tires that I can have fun with then get the 205-50-17 LRR tires I really want.
    The seller claimed they had 10 miles on them and he had the dealer take them off before he left with new wheels on his new car.
    I paid $720 total after having the tires reinstalled on the wheels and 'load force balanced'. No TPMS, he took them for his new wheels.

    I can't figure out what lug nuts are required with these wheels.
    I was given used looking 60° acorn lug nuts. The taper area on the wheels seems to touch the lug nuts correctly.
    I shouldn't need 'bulge seat' lugs.

    However, I see evidence that these wheels had that kind of lug for alloys with the washer. There is a large machined area for washers, but it has tapers too.
    I haven't tried fitting one to the car yet. I guess I need to visit the local Scion dealer and see for myself.

    What are your plans for lug nuts?
    And I'll be needing these, but first I need to make my own measurements:
    Hub Centric Rings $33 shipped.

    Oh, and BTW, from the detailed pics and report you posted, instead of spacers,,
    I'm considering using a fine sanding disc on a high speed and blending out ~ 3 mm from that corner of the caliper carrier.
    That thin joining bridge from the top slide area to the bottom one is there to resist spreading of the top and bottom of the carrier. In use that lower slide area takes all the torque of braking while going forward.

    I'll post detailed pics of this modification to the caliper carrier with before and after measurements.
    Call me crazy, but I believe that cast/forged steel piece won't miss a blended out 3-4mm....

    I like the hub centric rings that you came up with. I used the Gorilla Tuner lug nuts that I was using for my MOMO wheels. I have rotated the tires 5-6 times and they have been off a couple of times for brake checks and wheel balancing with no chrome chipping or rusting. They still look brand new. Mine are the chrome ones in the link below but they come in many colors. If I was purchasing again I would pick the "Black Chrome" ones.

    If I wasn't so excited to get my new wheels on I might have thought about the route that you are thinking. Shaving probably would be fine. Of course I would only do it to my own vehicle and never someone else's. I bet that it will only take 2-3mm at most. I pulled the trigger on the spacers so now I'm going to use them. I checked UPS and they aren't going to show up until later today.

    Here are pics of the new spacers. They did a good job on the machine work........I double checked the measurements with calipers. Spacers are 3.5mm thick. [​IMG]

    Those look like some good quality spacers. I was worried about the center ring and keeping the wheels centered. But, these will definitely keep them centered and cause less wear and tear on the studs.

    What don't you like about the H&R springs that is motivating you to go with Tein's? I hear the H&R's sit lower than the Eibach's and TRD's but not as low as the Tein's? Can you or someone else with this knowledge confirm?

    There is nothing wrong with H&R. I feel they are the best lowering spring for the Prius. Only reason I went we the Teins is cause they are coilovers & I wanted to go lower

    Sean, Vel (wotcher)and I compared our three cars at his house one day. Vel and I have TRD springs and Sean has H&Rs. Sean's car sat lower in the front but higher in the back than the TRD equipped cars.

    What is the difference between a lowering spring and a coilover? Sorry in advance for the lack of knowledge. lol

    Coilovers combine the strut and spring in one unit. They are also adjustable for ride height, which is why they are so desirable. They are much more $$$ though.
