I'm confused..... well, more than normal.

Your quoted specs (and pics?) are before or after spacers?

 

Oops. Sorry. Should be clarified.
The pictures I took are of my wheel set up without spacers. I just ordered them from concept Z today.
The wheel and tire specs however are my current set up.

 

no damage to the wheel itself?

 

So, you're going with 9" front at +10 and rears at 10.5 +5 and you're dropping it another 0.5"? Well, I have no say in this other than "If it fits and you're happy with it...."

Personally think it looks fine but your choice.

 

No, never damaged a wheel due to improper mounting.

Now if someone could do something about those mobile curbs that jump out to hit cars' wheels....

 

No garuntees I'm going lower. Hoping to see some similar setups. May need to roll fenders a little more. My next set of wheels and tires will be less function and more fashion. Lol. These are my track wheels/tires.

 

 

Sorry if this has been answered before, but I search the thread for z1 and didn't find anything.

I have a set of z1 motorsport 20mm bolt on spacers. One of the studs in the spacer is broken. These studs have a knurl diameter of over 22mm and I cant find a replacement. Can any body provide a part number for a replacement stud?

 

Have you tried contacting Z1?

Not sure I would want to mess with a replacement stud. I would just get a new set of spacers.

 

I've reached out to z1 but they have not responded. I also reached out to dorman with all the measurements and they can't help either.

Seems ridiculous to me to spend another $100 on a set of spacers for a $3 wheel stud.

 

Are there any markings on the head of the stud? Have you removed it yet, you may have to in order to find them.

As far as a new pair from Z1, that's way overkill. Not for Z1's pocket, but I am sure even they would say just replace the stud before buying another pair of spacers.

 

There are no markings on the stud. I've removed the stud and taken all the necessary measurements with a pair of digital calipers that give measurements in both inches and millimeters. I gave that information to the sales department at dorman and they said they don't sell a matching stud.

 

Finally heard back from z1. They don't sell the studs and can't provide a part number. Then told me I need to buy another set of spacers.

I know there are brands that have studs that can be replaced but they cost double what the z1 spacers cost.

I bought the car with the spacers and the broken stud. I didn't break it. I always start my lugs by hand. I might use a torque wrench to zip them down but not tighten them. I use a torque wrench. I've worked in a couple shops and slamming things together with a torque wrench is actually a pet peeve. My point is I'm not to worried about breaking another stud so I'm just going to buy another set of the cheaper z1 spacers.

 

cheap micrometer and a search in the Dorman catalog will work. I had to do that for my trailer

 

The only dorman catalog I could find on their site with measurements was for hd equipment where the smallest stud was m20.

Like I said I measured the stud and sent all the info to dorman and they told me they couldn't match it.

The stud is m12x1.25. total length approx 47mm. The knurl 10mm long with a diameter is 22.3mm. The head is 4mm long with a diameter of 27mm.
