I paid Mike Ward Performance (MWP) to order and install: performance rotors, posi traction unit and 410 gears approx. 2 years ago on my 96 Lincoln Mark VIII. The posi unit had to be replaced (which MWP did, but I had to tell him about it), the psger. side caliper top bolt fell off while I was on the freeway, again had to fix, told MWP denied responsibility, 1 yr into gears I took back to MWP due to a sound I kept hearing he couldn't find anything approx. 1 yr later rear gears seize due to ring bolts FALLING OUT and grinding in gears. MWP told me it was the way I drive, & told me repair would be about 600.00 (probably be more, always was with initial work). Performance parts are meant to perform, no?.. but to make sure I called 5 local shops, all agreed that the only way ring bolts could have fell out were due to improper install. Took it to different shop and they have told me that not only was it installed wrong, he used wrong parts. I am only presenting the facts, MWPs response to everything that was wrong and what other professionals said. I have also let JEGS know just because a shop buys a lot of merchandise does not mean they are capable of installing it and that JEGS needs to know more about the shops they recommending. Even the manager at JEGS (Josh) on Main St in Reynoldsburg said the ring bolts should not have fallen out. Due to my ignorance, not checking MWP out, I got sucked out of 5,000.00. I know another who paid him 40,000 to build a race car, not only do they not have a racecar, MWP "LOST" $12,000 worth of parts. The worst part is I've been driving my baby hard with bad gears and bad brakes....I feel like I handed my child to a pedophile to be molested, paid 5 grand for it and now I will have to pay another 1,000 to make my Mark VIII right again.
