Ok, I have read up some on the topic and still nothing. R wheel spacers safe??? I realize what putting these on entails. I just don’t know if it would comprimise the safety.
if you have proper extended wheel studs to allow for equal thread engagement as stock studs without spacers and you have a hub centric lip on the spacer then there is no reason why they shouldnt be fine.
if you try something like the Touge factory spacers, like i did, with the grade 5 home depot bolts they supplied and no hub centricity then you will probably die, like i almost did.
DON’T CHEAP OUT…when you buy your spacers. I have cheap 8-9mm ish spacers and I wouldn’t suggest them to anyone. Your best option is to buy rims in a good offset right from the start.
