Wheel spacers help

Hey guys, new member here but I've looked around the forums for a while without having an account and I was wondering if I could get some help. While reading through someone's build I saw that he added wheel spacers. To my knowledge they are basically to have your tires stick out, please correct me if I'm wrong. This is something I find very appealing, but I need some help. What brands should I look at, are there any flaws or issues, basically basics. Thanks for reading

 

search...spidertraxx..all pro...hub centric

 

All I find is products for sale, everythin seems to point to that brand. Anyone have any recommendations for size? And I read somewhere that they loosen up every 25 miles, is this true?

 

You need to install them with Loctite to keep the nuts in place (not the tire/wheel lugs), I have Spidertax 1.25's in the rear for like 30k miles now and have not had one problem with them.

 

Besides spidertrax (what I run), there is another company called BORA that also makes spacer in several sizes and are also hub-centric <--YOU NEED HUB CENTRIC!

Plus if you don't like the blue anodizing that spidertrax offers, BORA makes theirs in black.

All Pro comes in machine finish.

 

Thanks for the help guys, I'm planning on picking up a set of boras but I'm just having trouble deciding on a size. I'm deciding between .25 and .50
