I have a 2013 base model Prius C. I'm wanting to space out the wheels and get aftermarket wheels that fill out the wheel well. I was looking for suggestions on spacer width and wheel size?
Do a search, there's a few threads, IIRC, by a member called Mahout who used to rally his PC. He had a few specs on wheels.
If you just buy the right offset wheel you don't need spacers. For example That's a 6" wide wheel with a 42mm offset. Tires are 205/50/15. There's a few different wheel offset calculators online that you can use to figure out exactly what offset and width will fit your needs.
lol Wheel design usually plays into it a lot. Which is one of the reasons why I bought wheels that have spokes going to the outside edge. Since they are similar design, I'm going to say its all in the photography. Take a photo at a similar angle of your , and you should see a big difference. Particularly if you have access to a camera with a wide angle lens. A fish eye can make them look REALLY big lol, although looking back I wish the lighting was better in this shot. And now thanks to you I need way bigger brakes up front!
