Michigan Motorsports

"Trash service. First time customer , 900 dollar order returned for some unknown reason. No number to call to talk to somebody. All I got was “you’ve been refunded” never will I purchase from here again. As an engine builder was looking forward to doing business here but not worth it."

"I ordered a rear main seal kit with an oil pan kit, the reason for the 4 star, whenever i took everything to the mechanic said i was still missing one of the rubber washers. uggg, it may not be part of the kit, but with today tech the system should offer it. the price was great, and so was the material i did get in"

"I'm here to leave a review about Michigan Motorsports tuner Zak! He helped me the entire way through my build on my 5.3ls along with doing a 4l80e swap, the dedication he has to help you figure out the unknown is mind blowing and the least I could do was leave this review! I recommend anyone planning on getting a tune for their ls engine to go through Michigan Motorsports and you WILL NOT be disappointed!"

"I ordered a Michigan Motorsports camshaft kit for my Camaro and Corvette nearly two years ago and have driven both cars hard on and off the track with no issues. Anytime I order from Michigan Motorsports I get exceptionally fast shipping and the customer service is great. Can't recommend them enough"
