Well, I've seen a few postings here and there asking if it can be done, but no one post actually providing all the information needed to actually do it. I just got finished mounting the wheels on my 06, so here are the details.

tC1 Wheel
17x7 +45mm Bore 54.1

FR-S Wheel
17x7 +48mm Bore 56.1

The FR-S has a larger bore and is inset 3mm more than the tC wheel. If you try to place the FR-S wheels on the front, the wheel spokes will interfere with the brake calipers. The rear wheels clear the calipers with no issues.

In order to clear the calipers and bring the wheel out a bit more than stock, I decided on 10mm spacers all the way around. A 5mm spacer will allow it to clear the caliper, but the spindle shaft will push out the center cap of the wheel.

I ordered the spacers (Hub Centric to Vehicle and Wheel Centric to Wheelspacers) from here:

Now, that I have spaced out the wheel, the stock length studs are no longer sufficient for threading the lugnut. I could only get about half a thread with the spacer in place.

I ordered the Ichiba +50mm (TO-12550) studs from here:


Once I replaced all the studs, the wheels went right on, with no rubbing or clearance issues. This is with TRD springs.

Hey I have a question about the amazon extended studs. Is the price for individual studs or a whole set or just one rotor?
Edit: Scratch that I can see that it's for single studs. Another dumb question until I'm able to call the motorsport-tech guys. It's a hubcentric ring and spacer in one right?
Thanks

You got it.

I think that looks great and was considering doing that to mine...
Thanks for the info on what you did!
I'm a noob, so when I order the spacer, I want the bore dimensions of the FRS wheel (56.1), right?

The website will walk you through the steps, but essentially, you will pick your year/make/model (it will know the correct diameter for the tC), the thickness of the spacer, and then the bore of the wheels you want to adapt. You should end up with something like this:

Spacer Configuration
*********************
2006 SCION TC
Your Bolt Pattern: 5x100mm
Your Hub Diameter: 54.1mm
*********************
Type: Spacer
Hub Centric to Car & Wheel Centric to Wheel
Thickness: 10mm
Center Bore: 56.1mm

Nice not bad, I'm looking in a different direction but did wonder about this idea,
