grumpyvette Posted January 22, 2009 Author Share Posted January 22, 2009 wheel repair, and widening and narrowing ok many times youve seen a custom set of wheels you like but they don,t come in the correct width for your application, or youve got great wheels but youve screwed one up and it needs repairs, sometimes you just want wider tires and your current wheels won,t fit that tire width correctly or youve seen some killer (ford, caddy,nissan ETC,) wheels but they don,t come in your ideal bolt pattern or width. theres several shops that specialize in doing the necessary mods and reworked wheels can be just as strong or stronger than new wheels if the works done correctly.... BEFORE LOOKING INTO MODIFYING WHEELS DO AN EXHAUSTIVE SEARCH ON NEW WHEELS,THAT MAY WORK CORRECTLY, SIMPLY BECAUSE THE AVERAGE COST, OF MODIFICATIONS TENDS TO RUN BETWEEN $125-$200 PLUS PER WHEEL,(IVE SEEN STOCKCAR STEEL WHEELS DONE FOR UNDER $70 EACH) and VERIFY THAT THE TIRES AND BRAKES YOU WANT ARE AVAILABLE AND WILL FIT THE NEW RIM SIZE example I had a dana 60 rear differential from a PLYMOUTH BARRACUDA installed in my CORVETTE , the bolt pattern was differant and I wanted disc brakes that would not fit the 15" drum brake MOPAR wheels that looked crappy anyway, and 17" wheels were not even an option in the 1970s on CUDAs so if I wanted matching 11" wide wheels what can you do? well, its not cheap but it is something you can do, and with STEEL WHEELS its a good deal cheaper than with aluminum in many cases. but you can have almost any wheel fabricated, to match the lug pattern, back spacing, etc. you want, if you can supply the basic wheels of the correct inner and outer dia. the work cam be as simple as cutting and rewelding and reballancing the wheels, it can be far more complicated so ask lots of questions before commiting to the project, and try to deal locally as it tends to remove some possiable problems if you can deal face-to-face with the shop. the key is finding a RELIEABLE SHOP THAT DOES QUALITY WORK, your local stock car track guys should be very familiar with who does the work in your area on steel wheels and many times the same guys repair and modify aluminum and custom wheels.the KEY in getting a good result is in dealing with a quality shop with a long history of good customer feed back and doing VERY PRECISE MEASSURMENTS and suppling a PRECISE diagram , because your going to get almost exactly what you request in back spacing, dimensions and lug patterns , if you measure wrong your screwed and youll need decent wheels to start with, (sometimes 8 old wheels will be required to build 4 new wheels). heres three shops off the internet, and one had multipule links with bad =feedback http://www.weldcraftwheels.com/Wide.htm http://www.thewheelsmith.net/ heres two that do custom repairs and widening http://www.stocktonwheel.com/wheel_widening.htm stocktons had lots of bad customer feedback pop up when I did an internet search more wheel related info. http://www.carcraft.com/techarticles/3636/ http://www.high-impact.net/wheels/backspacingillustration.htm http://www.custom-wheels-n-rims.com/WheelTech/wheel-backspace.htm http://www.rsracing.com/tech-wheel.html#backspace http://www.intercotire.com/html/body_true-mph.htm http://www.kormanfastbmw.com/ttiredia.htm http://www.rsracing.com/rscatalog/prod-index.asp http://www.rsracing.com/glossary.htm#patch http://www.miata.net/garage/tirecalc.html http://www.geocities.com/steve.knickerbocker/tires/tirediam.htm http://www.dougrippie.com/drm/brake_conversions.htm#C4%20Corvette%20DRM%20Wilwood%20Brake%20Kit Link to comment Share on other sites More sharing options...
boardkid280z Posted April 6, 2009 Share Posted April 6, 2009 I didn't see this link anywhere in this thread and it is a great reference for stock wheels with dimensions and weights. http://kmhafer.datsun510.com/wheelchart.htm (if the link quits working, the page is on http://www.dimequarterly.com under Technical -> Suspension) Link to comment Share on other sites More sharing options...

jnonni99 Posted May 4, 2009 Share Posted May 4, 2009 Hoping to put 16" tires and wheels on my 75 280z. Has anyone done this and it looked good (proportionally)? Did they rub on the wells? Did ride comfort increase or decrease over 15"? Tire size, wheel size to make it work (off sets)? Thank you!!! Link to comment Share on other sites More sharing options...

vega Posted November 26, 2009 Share Posted November 26, 2009 We should have a minimum and maximum to rim widths and what will fit with stock suspension somewhere. Link to comment Share on other sites More sharing options...
crazyoctopus Posted January 5, 2010 Share Posted January 5, 2010 I remember seeing somewhere that to clear stock coils you need at most a 4.5" or 5" backspace; anything under that (4.25, 3, etc) and you should be fine. The width of the wheel depends on backspace, and tyre size. Link to comment Share on other sites More sharing options...

The width of the wheel depends on backspace, and tyre size. No way a 4.5" or 5" backspace 13, 14, or 15" wheel is going to clear stock coils.

crazyoctopus Posted January 6, 2010 Share Posted January 6, 2010 So then what is the maximum backspace a wheel can have on stock coils? Link to comment Share on other sites More sharing options...
crazyoctopus Posted February 6, 2010 Share Posted February 6, 2010 well i just ordered a set of 15x10 with 4.5" backspacing all around so i'll tell you if i need a spacer, but from all of the research that i have put into it 4.5" is the maximum that you can do with stock suspension. i'll post pictures as soon as i get them and install them Link to comment Share on other sites More sharing options...

1976 zdevil Posted May 25, 2014 Share Posted May 25, 2014 Hi guys I just bought the zg wide fender flairs. For my 1976 280. They add 3 1/4" in the front & 3 3/4 to the rear. I'm wondering what is the largest & best wheel and tire setup. With the space I now have. Im Also looking for offset spec so they don't rub the suspension. It is stock for the time being. I'm obviously planning to lower the car as far as functionality always. No crazy chamber. The below pic is the look I'm going for. Thanks for you time guys.

Incognitjo Posted November 13, 2014 Share Posted November 13, 2014 You now what I love? I love that anywhere you go in the forums regarding wheel and tire size, there is literally NO LIST anywhere that I have been able to find of verified wheel and tire combo's that work on the Z's. A whole lot of talk about what may or may not, but nothing solid. It doesnt make sense to me. It either does or does not fit, you either have to cut/roll or dont. Why cant anyone just post a flipping list of tire combos that work? Link to comment Share on other sites More sharing options...
Jambolito Posted May 1, 2015 Share Posted May 1, 2015 I agree Incognito, I cant find a list like that anywhere and it would be so stinkin helpful. Link to comment Share on other sites More sharing options...
