      Thanks for the link. I tried VAC but didnít think of AKG. BTW I found a set from a fellow member already. Thanks.

        Is VAC no longer selling these? I need a set too.

          Don't these put a ton more shear on the bolts, causing them to fail when loaded on track?

            Do you have an example of failure to share? Shear stress is not dependent on the length of the bolt...

          Do you mind elaborating? My car will be a street car, but your commentary seems concerning.

            Theyíre backordered from VAC.

            Iíve had these spacers on my car for 5-6 years. They seem to hold up well through many track days and autox. I do inspect and torque them at every event.

              For now I think I have to eat my words - I thought I had read commentary here on S14 about an issue using these spacers, but I cannot find anything. Apologies for stirring things up, I'll keep looking and come back if I find anything.

                Just called VAC today. They are making a fresh batch of spacers soon. They said order should be open in a week or two.

                As for reliability, the spacers have good fitment, and the bolts are rated 12.9, stronger than stock. I think itís important to not over tighten the bolts to keep the threads in good grip.

                  There was some discussion on the SIG about it, I had started the discussion and someone responded saying they can fail, but it was only in reference to hard tracking, which I will not be doing with my car. I never got more of an explanation on why or how they fail, hence my question to you.

                    FWIW I've had 13mm spacers with grade 12.9 bolts on my track car for years, no issues. Install the bolts with blue loctite and torque them carefully to spec. Check them regularly! I've never had one loosen, however.

                      I just called VAC and ordered a set of 19mm. They are scheduled to be made on their CNC machine tomorrow or Wednesday. Then they go out to their anodizer, so I expect to have them in 3 weeks. He gave me the option of sending them out in raw aluminum finish, which cuts delivery time in half.

                      Give Brian a call at VAC, he'll take the order now. brian@vacmotorsports.com
