I took my 2021 Supra in for an alignment on a Monday around 4pm, Tuesday morning (around 9am)…read more~20miles of driving later my driver side axle broke, due to the inner CV Joint bearing cage failing into pieces. After reviewing my dash cam footage, I saw several things that led me to write this review: 1. Techs were very non-nonchalantly chatting about taking the cars they work on test drives, even going as far as saying that they've purchased their cars because of test drives at the shop. Is this a red flag? maybe... 2. Tech that performed my alignment can clearly be heard saying he is about to full send it. 3. Tech proceeded to joy ride my vehicle, high-revs, manual shift, play with radio, etc. Would my axle have broken on that day, regardless of my visit to Auto Science? Who knows... but I certainly I wish I could go back in time and NEVER trusted this shop with my property, broken or not. The shop's response: 1. Refunded my alignment... 2. Spent countless messages back and forth / uploading videos / receipts / etc. 3. Stated a couple times they would be less inclined to help if I left a negative review 4. Offered me $250 to help towards fixing the car - I decided to stop wasting my time emailing them at that point. I guess some people would think $250 is fair, since there is no tangible evidence the test drive/alignment resulted in a broken axle... I am not one of those people. I've spent an insane amount of time and a lot of effort to get my car towed/fixed at home, this doesn't even being to cover it. My opinion: It is impossible for me to treat the axle failure as an isolated event, I didn't even get a chance to push the car before it broke. TL/DR: Tech took my car on a joy ride and my driver side CV Joint blew up around ~20miles later.

Dropped off 2 PWC cylinders on JULY 20TH to be blasted, bored, honed, and decked. Was given an…read moreestimate that they would work on them AUG 11TH and should have them done mid to late Aug. Called them on AUG 23RD and was told they blasted them and should be a few more weeks. Ok, no big deal I understand delays happen. Called again multiple times in mid/late Sept and got the same response. I'm starting to get a little frustrated at this point. Called again beginning of October and the same thing "the tech is measuring them and we should know in the next few days what pistons you need, I will call you once I know more". By now boating season is wrapping up. Finally said screw it and drove to the shop and picked them up OCT 24TH. During the span of 3 months, I never received 1 call about the status of the work, delays, or any info. Clearly my business is not important to them so I decided to take it elsewhere. I've been more than patient and understanding about the delays, but at a certain point I'm tired of being lied to. If you're a racer or have a trip or some sort of hard deadline you need a project finished by, I'd recommend going elsewhere. Also, in regards to the media blasting that they did do, I was told the coolant passages would be cleaned out and cylinder looking like new. Still lots of paint and corrosion everywhere on the cylinders and coolant passages. Lack of attention to detail and care for the customer. Will never do business with them and do not recommend.

I had a problem with a 5.7 hemi 3rd gen vvt block bought elsewhere and when I built it out that…read moreengine blew oil out of the rear crankcase seal. The engine did not run for 30 seconds before blow-by created a big problem. That engine builder was evasive at best. I took my block to city motor supply to have them mic the cylinders. I already knew the problem was on driver's side rear cylinder and I told city motor supply nothing. When I drew out the pistons I found oil between the rings on . Blow by. But I wanted verification. It took them about 5 minutes for no charge to tell me that the previous shop bored 7 cylinders at 20 over and the last cylinder 30 over. The builder put in all 20 over pistons/rings. Thanks for nothing. City Motor Supply dropped what they were doing despite me not calling ahead to check the block. They suggested either going 30 overbore to match them up or sleeveing the 30 overbore cylinder back to 20. I had a bowling buddy who worked in their shop building engines for years. The thing about reviews is that these shops push through a lot of blocks. People with a problem that doesn't get resolved gets a review. All the machine work that is ok you don't hear about. I had buddies in the past who got blocks from city motor supply and didn't have a problem. I appreciate their kindness today and that they independently verified what I already knew.

I am giving City Motor Supply a 2-star review, only because management *attempted* to make things…read moreright, but ultimately failed - again. I recently took a fully-stripped LT1 block and aluminum heads to CMS for their "Stroker Performance Block Prep" and a "valve job" on the heads. What I got in return was a damaged block, covered in cheap paint, and heads now requiring extensive repairs to make them usable again - maybe. When I dropped off my parts, my "customer service rep" - David - provided very little insight on the process, requirements and expectations of services being provided. When I attempted to show David all of my components in the parking lot, he was quick to respond with: "Let's just go inside." My request was to line hone, bore and deck the block, along with the CNC machining required to make room for the 400 crank. I also indicated that I was planning to personally put new valves/springs in the heads. Finally, I stated that I wanted everything "cleaned up, true and ready for reassembly." I was told it would take a couple weeks. OK. I received a call indicating that my parts were ready for pickup. When I backed my truck up to load the block, it was evident that my custom engine cradle was gone. My freshly prepped block was now wrapped in plastic/cardboard and sitting on a dolly. In order to get the block into my truck, the block was rolled onto the pavement and then lifted by hand. This was FAIL #1. This is where things take a turn for the worse... When I returned home, unwrapped the layers of plastic and began inspecting the work performed, I found the following problems: - THREE of the OEM main cap bolts (for the windage tray) were missing and replaced with random bolts. They used random, 3rd-party bolts to line bore the main caps. BIG FAIL #2. - The #3 main journal has a protruding nick on the bearing mating surface, preventing the shell from sitting flush. BIG FAIL #3. - The register on the #4 main cap is LOOSE, allowing you to wiggle the cap by hand. There is no "click" when mating it to the parting line. BIG FAIL #4. - The heads were not cleaned, carbon still in the bowls, seats re-cut using old guides, inconsistent seat heights, one random guide installed, copper spray paint across the top of the heads, the name "Jeff" written on them in blue marker. FAIL #5. - THREE of the intake runners have been damaged by over-clamping / ham-handed behavior. FAIL #6. - The name "Jeff" was on the work order; "Josh" was on the invoice. Whenever David would give me specs, he would call me on the phone. Did he think he was talking to "Josh" or "Jeff"? FAIL #7. - The original water pump bearing was not returned. Old parts should ALWAYS be returned to the customer. If this isn't common practice at CMS - it should be. FAIL #8. - The decking of the block was not machined cleanly. The chamfering on the top of the cylinder bores also varies from side-to-side. Was the block decked more on one side? BIG FAIL #9. - They painted the block with cheap black paint. This was NOT REQUESTED, nor discussed. FAIL #10. The block and heads were taken to another shop for inspection. As expected, all cylinders were .002" overbored from what was requested. The new main journals are all line bored beyond factory specifications. Everything is loose AF. The heads will need to be repaired and rebuilt correctly. I'll never be returning to CMS. Dallas deserves better than this. If you care about the attention to detail being shown towards your build, you'd be better off spending a few more bucks and looking elsewhere. If you REALLY want to avoid a headache, just go get a crate motor from Summit, Jeg's, Speedway Motors, Blueprint, ATK or Skip White Performance...basically anywhere else. At least you will get a warranty on the motor. As a lifetime gear head and a relatively new resident of Dallas, I was hoping to build a relationship with a shop that I could trust to perform the work at a level that portrays pride and craftsmanship. Communication and customer service are just as important as the guys turning the wheels in the back. I found neither at CMS. Bummer. 2-stars.
