Anyone know the offset for the 15x6" stock steelies?

I'm getting some spare rims and I wanted to take the guess work out and do an offset calucator to make sure they fit right, but I don't know the stock 4 lug steelies offset. Anyone know it? By the way, I plan on having 16x7 with 38 offset, does that sound about right?

I think it is +40. 16x7 +38 is weak as hell offset wise. I had 7.5 +32, and it was almost close to being nearly acceptable.

Hmm, I think you confirmed what I was thinking. I have some staggered Circlaz 17" with 8 in front and 9 in rear and those are like 35 and 32 offset I believe. Those are dope rims but I want some bang up rims, ya know. I don't use spacers so I think the 38 would be weak too. I guess I'll just keep an eye out for something around 35 then.

What about spacers? Bad idea?I have a pair of 10mm spacers I want to put in the back. Will it cause under steer?
