15mm spacers installed then horrible clicking noise
I bought some spacers from ecs tuning 15mm. I also bought some extended lug bolts ball seat M14x1.5x45. Stock bolts are 30.7 long so I thought I should be good to go. Spacers fit perfectly on the hub no issues. I put them on the rear and went to move my car to a different spot and was getting this awful awful clicking noise. Really loud. All I did was move the wheels out 15mm. Stock Sport 17" wheels, not lowered. Tires not rubbing anywhere. Bolts all torqued to 81 lb ft. Anyways, I immediately removed the spacers and remounted the wheels and no noise. How is this a fail? wtf was rubbing/clicking? Any help is appreciated.

I can't remember if I reapplied my parking brake then released it or just pulled on the release again to make sure it wasn't stuck on. Maybe I'll have a wheel shop install them. My spine is not so good after two back surgeries.

I think I found the prob. ECS shows my stock lug bolt as being 30.7 shank length. Pelican parts shows it at 26.5. I chatted with Nate at ECS and he confirmed a 45mm long bolt would be what I need. I measured one of my stock lugs and it's not 30.7. Looks a little longer than 26.5 but well under 30mm. I was grinding up my parking brake parts from using a 45mm lug bolt. I should have spun the wheel before letting it down off of the jack but I didn't.

I had the same issue, but my clicking sound went away without having to do anything. My car was parked for storage and i would roll it out on the odd day to let it run and that's when i heard the clicking sound. But now when i take my car out i don't hear it anymore, should i be concerned or does that mean that its all good?

Nah you probably wouldn't get a light.
And yeah, your lug bolts are too long. Might want to make sure you didn't damage any of the parking brake.
Same thing happened to me. I cut my rear lug bolts off and ground the edges down nicely.

BTW...how do you know if you damage your e-brakes? Any errors on the dashboard or would it just not work at all?
