Bobibbles Posted June 9, 2016 Share Posted June 9, 2016 Basically title. Yes I have been researching but not with all of those 3 specs matching. Just want to get a more definite answer. My 280zx is all stock on suspension as far as I know. I may get new struts since I am sure they are shot due to the squats I get from acceleration. Thanks in advance Quote Link to comment Share on other sites More sharing options...
jhm Posted June 9, 2016 Share Posted June 9, 2016 Maybe I'm missing something here, but wouldn't the backspace be 5.0" with 0 offset on a 15x10? Not sure if you saw this discussion, but it may have some useful info for you: http://forums.hybridz.org/topic/110251-custom-wheels-9wide-19mm-offset/?hl=%2Bwheel+%2Bwidth+%2Bbackspace&do=findComment&comment=1030715 Quote Link to comment Share on other sites More sharing options...
74_5.0L_Z Posted June 9, 2016 Share Posted June 9, 2016 A 15x10 wheel is actually 11 inches wide measured at the outer edges of the rim. The lip of the rim is about 1/2 inch on each side. So yes, a 15x10 wheel with 5.5 inch backspace will have a zero offset. I have no idea if they will fit on the back of a 280ZX, but they would fit on the back of my 260Z. I have sectioned struts with coilovers and a Subtle Z body kit. I currently run 15x10 on all four corners of the car with 5.25 inch backspace. On the front I run an 1/8" spacer, but no spacer in the rear. The wheel and tire clear my rear struts by about a 5/16 inch. Quote Link to comment Share on other sites More sharing options...
Bobibbles Posted June 9, 2016 Author Share Posted June 9, 2016 I have heard S130s can fit bigger wheels compared to S30s. So if it fits your s30 rear fenders then that's a good sign. However you do have a body kit. Did you ever fit them before putting on the kit? Quote Link to comment Share on other sites More sharing options...

74_5.0L_Z Posted June 10, 2016 Share Posted June 10, 2016 The wheels were made by Spin Werkes (Series 82), and were made custom to my specifications. They wheels are light, good quality, and were very reasonably priced when I had them made in 2008. Unfortunately the company has changed ownership, and I don't know if the wheels are still available or manufactured to the same standard. I only use the car for autocross and track days. The tires I have used on these wheels are Hoosier 275/35-15, Hoosier 23x9.5-15 (FA Slicks), Avon 10.5x23.0-15 bias ply slicks, and now I am trying Avon 240/600-15 radial slicks. I can't think of any street tires that would fit these wheels without looking goofy. Quote Link to comment Share on other sites More sharing options...
Bobibbles Posted June 10, 2016 Author Share Posted June 10, 2016 Any other comments? Really tempted to pick up a pair of 15x10s on my local craigslist. Quote Link to comment Share on other sites More sharing options...
roger280zx Posted June 16, 2016 Share Posted June 16, 2016 It has been a while, but I fitted 15x10 5.5" on 11.5x23x15 under stock fenders in the back. I'm pretty sure the rear fit with out spacers, but the front no way, not even with 30mm spacers. Fronts were rubbing the strut. Quote Link to comment Share on other sites More sharing options...
