Nothing but problems, definitely not a simple install
Nothing but problems. Definitely not a simple as just bolt on. First the pulleys did not fit on the shafts. I assume this was because the holes weren't masked and clear coating made them under size. Then the harmonic damper pulley stuck out an 1/8 more then it should. I got all that fixed and then the tensioner says use the bottom set of holes but move it up if you need it tighter but the pulley on the tensioner hits the bracket and so it only fits in the bottom holes. They do look pretty though.
