Hey guys,
I was wondering if anyone had put on a set of the 2005 Legacy wheels on an SS? How much would it throw off the speedo?
Thanks

it's very little, like 4 km at 60mph, but it also depends what height tires you are putting on, my 16's were 1/8th bigger than my 15's cause they had a lower profile tire

Here's a tire size calculator:
