Rio24 Posted April 5, 2020 Share #1 Posted April 5, 2020 Good Morning, a new issue showed it ugly face after I installed new wheels. When from 15x7 to 15x8 and now R/F tire rubs bumper when turning left. I have read that nissan designed R/F caster to lead a little , but this is too much. Can this be adjusted? Also noticed that left front wheels poke is more that right side by 8mm. Any suggestions? Has anyone adjusted subframe for this reason. No frame damage is apparent Link to comment Share on other sites More sharing options...

The "bumper" is that chrome covered thing on the front of the car. 1 Link to comment Share on other sites More sharing options...
Rio24 Posted April 5, 2020 Author Share #3 Posted April 5, 2020 Hello Zed. It rubs when driving. I have it raised now to take wheels off. Sorry I shouldve made it more clear. It rubs on sheet metal on lower part below the chrome bumper. Wheel well area Link to comment Share on other sites More sharing options...
Zed Head Posted April 5, 2020 Share #4 Posted April 5, 2020 Check your T/C rod bushings. They can get old and loose and let the wheel move forward. New bushings might buy you some room. Link to comment Share on other sites More sharing options...
Rio24 Posted April 5, 2020 Author Share #5 Posted April 5, 2020 Thanks Zed. All bushing are new. Replaced them last year. I did check them out and the bushing are correctly installed and nuts and even and tight Link to comment Share on other sites More sharing options...
Zed Head Posted April 5, 2020 Share #6 Posted April 5, 2020 You can only adjust toe on the factory stock Z's. Here's some aftermarket stuff. https://www.cxracing.com/control-arm-camber-kit 1 1 Link to comment Share on other sites More sharing options...
SteveJ Posted April 5, 2020 Share #7 Posted April 5, 2020 I experienced the rub when I went with bigger wheels, though I'm not sure you will like my solution. The lower valence was pretty beat up on my car, so I swapped out to an air dam. The air dam did not have the clearance issues that I had with the stock valence. 1 1 Link to comment Share on other sites More sharing options...
jfa.series1 Posted April 5, 2020 Share #8 Posted April 5, 2020 Your photo shows a tire size of 225/50X15 and a calculator says you are about 1" smaller diameter than OE so that is not the problem. Other than the 8" wheel width being the issue , are you running a 0 offset? Link to comment Share on other sites More sharing options...

Using the same times as now (225/50) and had no issues. You can clearly a smaller gap in front of tire compared to the left side. Link to comment Share on other sites More sharing options...
cgsheen1 Posted April 5, 2020 Share #10 Posted April 5, 2020 How thick is your spacer? Did you use the spacer with your previous wheels? The lower valence has some adjustment. Have you tried loosening that side to see if it will move forward? (We see quite a few Z's with this issue when owners are changing wheels and tires... I had this issue when I first mounted my sons Rota Grids on Goldie. -> airdam) 2 Link to comment Share on other sites More sharing options...
Zed Head Posted April 5, 2020 Share #11 Posted April 5, 2020 (edited) If the tires have a wider wheel base their arc will be greater. The arc of the turn can also affect what the wheel hits. You could always "cheat" your T/C, Take the inner sleeve out and cut a half inch off. Put it back together and adjust to. Might get you there. Anyway, the reality is your new tires rub. And, tires can have the same specs and still have a different shape. I learned this in the past but the width number is actually the sidewall width, not the tread. I always thought it was tread width but it's not. https://www.tirebuyer.com/education/understanding-tire-sizes-and-types Section width of tire (Example: P 225/45R17 91V) The three digits following the service type prefix (if present) tell us the cross-sectional width of the tire in millimeters. In the example above, the tires width, measured from the widest point of the inner sidewall to the widest point of the outer sidewall when properly mounted, is 225 millimeters.

I'm going check the valence for adjust now. Thanks! I'll let you know soon Link to comment Share on other sites More sharing options...
