Problems with wheels spacers...HELP!!!

Is this your setup? those calipers look sick with the red and white toyota writing!

 

I too bought some ebay 1" spacers which were not hub centric for my 2010 Tacoma. Big mistake! I had a vibration at 50+ MPH. The esteemed ebay seller will not rufund because I "used" them. I really like the looks of my truck with the spacers so I will buy a quality set this time around. Thanks for the input from this thread!

 

OK my turn to ask a stupid question… is it necessary to run extended Lugnuts for the front with the wheel spacers? I think I understand you do it for the Front because the wheels move. Should I run them on the rear to just to be safe?

What dimension Lugnuts should I buy? Obviously the 12 x 1.5 but if I buy the spidertrax or all pro spacers is there a length that should keep in mind?

Are the extended threads for the lugs that hold the spacer on or for the lugs hold the wheel to the spacer?

Sorry for all the questions… I've been 100% anti-spacer until I realized the look I want isn't possible without them. I've been burned on spacers before, not being good quality or incorrect fitment and I don't want to make the same mistake again
