I dropped off my C6Z on Monday for their 690hp package and picked the car up on Wednesday. They have great workmanship and don’t keep your car as long as a lot of other shops. This is my second build with these guys and it won’t be the last.

Matt is a wonderful person to work with and has done almost all of the work on my 2013 GrandSport. I really appreciate the quality of work and patience that this shop has with me. 100% must go to for any performance mods!

Gave great advice and consultation. They swapped my truck motor out in under three days and did a great job.

These guys are the real deal! They knocked it out of the park with my C6Z. Their turnaround time for a cam was a day and a half and made awesome power in pair with their LS7 head work. Will be using 21st century exclusively from here on out.

BEST PERFORMANCE SHOP IN DFW!!!
Let me start by saying that Matt, John and the 21ST CMC team are very good at their jobs! They have integrity in their work and it shows time and time again. Whether it’s a quick question on the phone or service on a vehicle, I know that I’ll always get an honest answer and a good job done always.
I had the pleasure of finding this shop a couple years ago when I brought my 2nd gen CTS V to them to be tuned and have some parts installed and the whole experience, tune and install was flawless. Now fast forward to now, and they have since tuned my current supercharged 2009 Corvette and it’s been a joy to drive every time I get in it. They are the only people in DFW that I want to service my performance vehicles!

This is the only place to take your C8 or other Corvette. They are very knowledgeable and honest. I came in wanting a full exhaust, but Matt talked me down and told me where to spend my money based on what I was looking for. Got the Borla Atak AND I LOVE IT.

Bought an '02 Z06 from CMC about 2 years ago. It's been a fantastic car. After spending some time wrenching on the car I can tell they do great work! (came with CMC mods installed).
I would 100% have my trust in these guys.

These guys are top notch! I recently rebuilt my LS1 in my 98 Trans am with more power in mind but keeping it N/A. Talked to John originally and he got me in within a week to dyno tune my ride. Matt is a wiz with the tune with over a couple of decades experience. I cannot thank these guys enough! Great people, great shop! These guys are legit!

21st CMC is the ONLY shop I will allow to touch my cars. They built my CTS-V and now work on my Z06.My CTSV never gave me one problem in 5 years. Matt's tune was spot on and ran hard.They deliever as promised when they say they will and the bill is always what they quote me for a job. That is very rare in the performance industry.Matt's customer service has always been excellent. He's honest and will shoot you straight. Most shops will push hard to get you to buy parts you dont need to just run up the bill and Matt/21stCMC NEVER does that. They are my go to shop and no one else will work on my toys. Thanks 21STCMC!

Matt and John made the transaction super easy. Did the DOD delete on my Tahoe. Matt kept me posted on vehicle during the small delta of time it took. It is super easy and in and out less 4 days.Is worth the cost, yes the vehicle runs better and shifts smoothly. It's not jerking anymore from 4 to 8.I have used 21 Century services on my Corvette 10 years ago with perfect results.Only thing wish did this much sooner. Thank you.
