25mm+ slip on spacers
25mm+ slip on spacers
does anyone make a 25mm and up slip on hubcentric spacer that does not include built in studs? im looking to install extended arp studs and want to run a 25mm slip on spacer but have not been able to find any.
I'd check that sheer load rating on those before dropping on a spacer that thick.
I recall reading the nismo wheel studs actually had a higher rating when compared to the ARP ones

Yeah, as far as I'm concerned, it seems like the theory of leverage would come into play here. Why would you want all the pressure on the end of a long bolt when it could be closer to the base of the bolt (as on a v2 spacer with built in lugs)? Having the pressure closer to the base of the lug seems much safer in my mind, and with the spacer being bolted on at the base of the original lugs, there is no extra pressure there either.
For instance you put a ten lbs weight at the end of a long stick and the stick breaks much easier whereas the closer it gets to the base, the less pressure on the stick as a whole.

Ultimately the shear rating of the bolts is what we care about, how much force it takes to split the bolt in two at the highest stress point of the connection (in this case the wheel to rotor hat contact). Bolt will be shear rated and you trust it if your steel comes from America
. If the shear rating is enough (equivalent to OEM) then you are fine. The length of the bolt has nothing to do with its ability to shear, but keeps the lugs clamping force honest with more of the stud to hold on to. If your lugs were installed like a puss (under torqued) you are going to have a bad time (that's when a bending moment occurs).
Shear rating is based on what exactly? The fact that it will break at all? Because I'm pretty sure plain old physics would suggest that the shear rating would change over the length of the bolt based on where on the bolt you would be putting the pressure (you know, the way it does with every other material). But that's just my "christian understanding of science".
And I never said it wasn't safe. Obviously you can make a long bolt strong enough to withstand the pressure. I was wondering why you would want slip on spacers vs ones with built in lugs from a good brand. I am not saying all spacers with built in lugs are better than buying new, longer lugs, because that's not true, but if you have both side by side with similarly strong lugs, I would feel safer with the spacers that had built in studs.

whatcha talkin bout shear foe??
hubcentric..hubs take that load or at least most of it. Thats why I declined a set of spacers with hubcentric play.
Ichiba actually does a darn good job with their rings.
I wont mention this brands name.
Can the suds hold the torque and lateral wheel forces is the question.

The lateral wheel force is exactly where I would feel safer with everything being torqued as close to the base of the bolt as possible. That's where I've read stories about lugs snapping. Remove as many variables as possible including excessive lug length.

So if I have a 100 ton machine that grabs the bolt at each end and it breaks at 50 tons of pressure its gonna break at the same exact point if it was grabbed from the middle and one end?
