Take your pick. I bought mine from this website.
The 8mm spacers were 15$

Wheel Spacers

I have heard of engineers knocking cars back because of an increase in track, so if the spacers cause an increase in track that may make then technically a no no.

Few members have spent hundreds on getting sets custom made. I wouldn't have thought they were illegal, perhaps if they're too thick then they would be (or if they weren't professionally made).

I didn't even kno that too tight can make em come off that's ####

plus you want to make sure that theres plenty tread aswell for the nut to bit onto....

Nah, wheels can fall off even when not using spacers. The thing is they need to be tightened correctly, to correct torque and all four evenly. Too loose or too tight and there is a risk of falling off.

Hey do wheel spacers make or help ya wheels loosten off??
I think one off my mates mentioned it once and yesterday my wheel fell off while I was drivin and my wheel fell off but the thing is I knew I did all wheel nuts off tight. . . ?
