I'd like to know. Some pics and feedback would be great. I ordered a set that didn't work out for my wheelset. But now I'm thinking about still doing the spacers via a different route. I just don't like how the rear wheels look so far tucked compared to the fronts. I have Konig Deceptions in 17x7.5 that are +45 offset and they have a flush backside so my spacers didn't work because the stock lugs stuck out a bit. I'm thinking something like this instead: HUBCENTRIC WHEEL SPACERS 10MM 5X100 SCION TC 04+ W/ EXTENDED STUDS | eBay
I'm running a 5mm hubcentric spacer on the rears. I have the stock 17x7 +50 on my car now. I had my 18x8.5 +48 on previously.
