misterZ Posted December 1, 2009 Share Posted December 1, 2009 Looking at buying a set of these for my 280Z (lowered 1") but not sure if they fit with the 38 offset. Anyone have an opinion or experience with this specific model and if they fit w/o modification/spacers? Thanks in advance... Quote Link to comment Share on other sites More sharing options...
FlatBlack Posted December 1, 2009 Share Posted December 1, 2009 I do not have any experience with that wheel, but I don't think you'll be able to get around using spacers. I have the Rota RB 15x8s that have a +4 Offset, and I had to use a 1/4" spacer [and longer wheel studs] to get the 225/50/15s not to rub the spring perch.

Do you mean they may fit with spacers? I don't understand the offset concept; what unit of measure is the +38 and (out on a limb) I presume it's measured from the centerline of the wheel--hence the -/+?

deja Posted December 2, 2009 Share Posted December 2, 2009 Check this site. http://www.bigcustomwheels.com/rt_specs.jsp It would take a 1.5" spacer. I am running 1.5" spacers with my 40 offsets.

I did and it still doesn't answer my question. Thanks anyway. It would take a 1.5" spacer. I am running 1.5" spacers with my 40 offsets. Exactly what I was looking for thanks Dale!

Administrators RTz Posted December 2, 2009 Administrators Share Posted December 2, 2009 (edited) Wheel width is a 'must know' to answer the question. I did and it still doesn't answer my question. Thanks anyway. Tossing a bone... +38 means the center of the wheel would be 38mm closer to the center of car.

Administrators RTz Posted December 2, 2009 Administrators Share Posted December 2, 2009 (edited) I'd be surprised if we haven't covered this before, but here's a picture of my 240, 15x7, +38, 215/50/15 tires, and 1.375" spacers/adapters...

If you searched "wheel offset" in Google, then you would understand what positive and negative offset mean. Why, lookie here: http://www.google.com/search?hl=en&source=hp&q=wheel+offset&aq=f&oq=&aqi=g7g-s1g2 Quote Link to comment Share on other sites More sharing options...

Why, lookie here: http://www.google.com/search?hl=en&source=hp&q=wheel+offset&aq=f&oq=&aqi=g7g-s1g2 You assume too much as I took your suggestion and did that exact search w/ the same results last night and only validated what I had presumed to be the distance (in millimeters--`cause it was the most logical) IN (negative) or OUT (positive, street side) from the centerline of the wheel; however, the Google links didn't help with the answer I was looking for graciously provided by deja (RTz contributing). Maybe I didn't get far enough down in the weeds... Quote Link to comment Share on other sites More sharing options...
HB280ZT Posted December 4, 2009 Share Posted December 4, 2009 MisterZ, Not sure if this will help or not but I put my friends 17X7 +38 offset rims, 225/45X17 series tires on my 77 280Z with coilovers and in the back they cleared fine. Now the only reason that I could not check them on the front was beacause the hole in the middle of the rim was to small to clear the center hub assembly. Like I said may not help but!
