Jersey Posted August 9, 2003 Share Posted August 9, 2003 I'm looking for a cheap alternative to put the widest 24-25" tall tire on the back of my '73, just to run at the track. I know the 84-85ZX N/A rims have the same bolt pattern (4x4.5), are slightly wider than earlier rims (6.5") and have a 30mm offset which would put the tire under the wheel well a little more, but i'm not sure if it would be too much and rub the stock 240 strut tower? I was thinking maybe a 245/50/15 would work (also a little wide for the 6.5 rim..hmm) I'm just trying to squeeze the maximum size rear wheel on by getting it as close to the strut tower without rubbing it and also still drop inside the stock outer fender lip so it would slip under when lauching hard, creating ass drop. Thanks in advance for any ideas. Quote Link to comment Share on other sites More sharing options...
Guest Phil1934 Posted August 9, 2003 Share Posted August 9, 2003 Yes. Backspace is 4.96". Interference with spring is 1/2-3/4". Hopefully I'll get back to you on this later today with a plan, cheap spacers, long shank nuts, and the original Datsun washers, and possibly NAPA studs.

Jersey Posted August 9, 2003 Author Share Posted August 9, 2003 What size tires are mounted on your ZX rims Phil? Thanks for the reply BTW. Quote Link to comment Share on other sites More sharing options...
Guest Phil1934 Posted August 9, 2003 Share Posted August 9, 2003 I picked them up with 215 tires a few weeks ago, but it's for the nephew's car and I can never catch him home. Front only hit about 1/4". 6.5" is minimum recommended rim for BFG 235/60 DR so I don't think you can run the sizes you mentioned. Quote Link to comment Share on other sites More sharing options...
Jersey Posted August 9, 2003 Author Share Posted August 9, 2003 Ok, thanks phil. Keep me posted how you make out in the rear. Thanks. Quote Link to comment Share on other sites More sharing options...
evildky Posted August 10, 2003 Share Posted August 10, 2003 84-85 na wheels will fit the rear with 225/55r15 tires no problem, the fronts will hit the springs unless you have coil overs Quote Link to comment Share on other sites More sharing options...
QWKDTSN Posted August 10, 2003 Share Posted August 10, 2003 I'm running them. Check my album. I'm just running 215s. I've got coilovers, and in my particular application needed a 1/4" spacer at first. I fixed it so that it works without the spacer, but I run it anyway because I got used to the look of it being closer to the fender I get comments on them all the time but I don't think they're special. I just picked them up cheap because they were better than what was on the car when I got it. Quote Link to comment Share on other sites More sharing options...
Jersey Posted August 10, 2003 Author Share Posted August 10, 2003 Thanks guys. Just looking to put 'em on the rear for dragging so it sounds like it'll work. 225/55/15 works on a 6.5" rim without too much bulge? Sounds good. Hope it wont cretae a problem when i air them down to like 20psi or so. Nion, i cant get to any of your pics. Send me a few if you can...i'd like to see it. Thanks again.
