Hi guys, the other day I had a small problem where I lost two wheel bolts while driving on the highway. Luckily I heard the second one fall out and had to pull over three times to retighted the others as they were loosening up.

Anyway, it happened the night before I left for vacation so the car has been sitting as is in the driveway. I am in need of ordering two new ones, though I don't mind buying 5 if need be just to have extras in the future. My problem is, since I'm not home I can't measure the exact size of them.

I bought 15mm and 20mm spacers from ECS Tuning and they came as black spacers with silver extended bolts. I need the silver ones to match and I need the correct size. Would anyone be able to point me in the right direction of buying new ones? Please and thank you.


Obviously I should be purchasing from ECS, but which mm size would the bolt itself be? There are tons of sizes ranging from 26mm to 50mm. That is what I need help with. Basically which size mm bolt comes standard with 15mm and 20mm spacers.

You need 60 degrees,12x1,5 thread, 17mm head, conical seat bolts. Stock bolt thread length is about 25mm. So what you need is something close to these 25mm+15mm= 40mm, and 25mm+20mm=45mm. If you don't find that exact length, then little bit longer is better.

Thanks for the reply, I ordered 45mm, but had a chance to speak with a rep from ecs, and said they ship 43mm extended bolts with those size spacers, 20mm would work with 45mm but the 15mm mind be too long and not sit properly.

Hope this clears anything up for someone in the future.

That's why you buy different length bolts to each different spacer size.
