Im looking for wheels for my z and I found these... I was wondering what you think and if they will fit. I would really like to get wide wheels so the 10 inch would be awesome. Also does anyone know the quality of these?

None of the sizes listed will fit a Z. You need a 4x4.5 bolt pattern. With a stock strut tube Z you would need a -25 (4.5" back space) offset and you would have to run fender flares too. On a stock Z you can fit 8" wide wheel with a 0 offset on the back and a 7.5" wheel on the front with the same offset.

I do not think those are very high quality wheels. To get wide wheels like that for a Z you will have to spend big $ ($450+ a wheel) and have them custome made. The 15x10's listed are very heavy too. A good wheel in a 16x10 size weighs around 15-17 LBS and cost $450 (www.kodiakracingwheels.com)

If you are going to do it, go to a 16" wheel and you can get some good tires too. The 15" tires out there that are wide enough for a 10" wheel are not very good.

IMO unless you have a V8 with big torque, on a light car like a 71 Z the car will handel and feel the best with a 15x7 wheel and a 225/50/ tires on all 4 corners (with a sticky compound). Remember it is possible to over wheel/tire a car.

Won't this fitment lower the overall wheel/tire height...I did a +1 wheel conversion with 205/60 tires...wouldn't 225/50 be wider but also lower?

71datsunsZ,

The 15 x 7 with a bolt pattern of 4 x 4.5 with a 0mm offset will fit,

if the backspace is 4 inches. The best tire size is 225/50-15 at all four corners. That is a nice looking wheel, however if you are autocrossing are doing any kind of racing the wheel is kind of heavy. For daily driver you will be fine. Go to 1010tires.com and click on tech, they have a good tire height/width calculator. Also, go to rsracing.com, go to tech wheel and you see how the width and backspace works. The wheel height is reduced and your tach and speedo will be off, IMO wider tires, tucked under a Z is sweet:)

Added note,

Zguitar is correct 3.5 inches to 4.5 inches is the max on a non-coilover suspension. Wheel width greater than 7 inches, depending on the height of your car you will need flares or want flares because the tires stick out so far. Keep in mind also, Zs are finicky upfront with a lot of negative backspace and wide wheels. You expose yourself to other weak or strong areas of the suspension geometry.

Also does anyone know the quality of these?

When I sold wheels and tires for a living (prior career), Elite wheels were a low cost wheel of so-so quality. But I left that industry over 7 years ago, so I can't say that my impressions from then are still valid. A lot can change in 7 years.

At the bottom of the list of vehicles, is Datsun Z car, not under Datsun or Nissan, where you would expect it.

Yes, that size is around 24" in diameter and the stock size is around 24.75" in diameter. On the highwy your speedo will be off and the revs higher but neither one would be so bad to cause a real problem. A 225/50/16 could be used but there might be slight rubbing issues on a lowered car. The benifit would be better gearing around town with a 225/50/15.
