This was my first attempt at installing wheel spacers and it couldn't have been easier. I'm a handy guy, but when I was removing my first tire, I found my first lug bolt was cross-threaded and stripped. I was ready to call a tow truck. Ha! I kept at it though and before I knew it, the bolt basically fell off behind the rotor. Had to remove the caliper and rotor to retrieve the bad bolt. Luckily my dad(car guy) was nearby and took me to the nearest auto parts store to get a new one. The whole process for 1 wheel took 3 hours including the drive time, repair and install. I was stoked!The next 3 wheels were done in about 45 mins. As far as the spacers are concerned, I love them. The stance is just right on my Tacoma now. The construction is solid and the fit was perfect.
