I have 17x9 +30 p45r's .... They came with a set of 8mm non-hubcentric or bolt-on spacers, to clear the calipers...

My lugnuts have loosen over time, so I wanna go with a good set of bolt-on spacers perhaps ichiba or kics...

They both make 10mm or 15mm applications.. from previous experiences does anyone have any tips for rubbing issues or such?

A pic of the wheels w/ 8mm spacers, +22 resulting offset

 

you could try some extended studs...would be a hell of a lot cheaper than spacers

 

true true... i guess since i would have to go through the pain of extended studs to make it safer, I might as well get the lower offset resulting from spacers
