Hey R31 drift pig, post up some pics of your ke70 with the 15x8's man. I'm in the process of getting some wheels from yahooauctions, but can't find anything with a decent offset in the 8" wide category so I'm going for 7.5's with something around the -5 to -10mm offset. Ordered some from upgarage, but they were sold earlier that day.
But yeah, post up some pics, I was originally going for 8" 0 offset so wouldn't be too bad to see something around that.
What have you got up front? I'm thinking something like 7" 0 offset up front. Should be a nice fit with the standard guards rolled.
