Question about oem studs
 

I installed spacers over the weekend with extended studs and noticed the rear studs were shorter than the front studs. I checked online for replacement parts for kicks, and noticed sites claiming the rear and front studs are the same. Is this true? Also, what is the length of the OEM stud. I am currently at work, so I do not have access to mines. I am just curious, if anything, about this issue. Thanks all.

considering some folks had no issue mounting 20mm spacers with built-in studs, i think u might be onto something. my studs in the front (as well as many others) are longer than some of the other Z owners.

the oem studs are different, i have some spares in my garage at home

bump, id love to know the stud lengths as well.

So I measured them briefly recently. The rears were about 42mm and the fronts were 45mm in length. Interesting indeed. The reason I was curious was because I recently had 15mm spacers in the rear and upgraded to 20mm. I installed the 15mm spacer studs that were provided by H&R ( They are about 60mm in length). When i upgraded to 20mm, I wanted to know if I could keep those studs instead of changing out the studs in the 20mm spacer kit. So I decided to just keep the 15mm studs in there since the difference was between the OEM rear stud and the stillen stud was <2mm in length.
