What our customers say about us

Here's what people are saying about Spartan LSX Performance.

"My car was built by josh and his crew. They did an amazing job, i go to them for all my high performance needs."
Joel S.

"Josh has done all the work on my GTO, from engine through driveshaft to diff/gears. He is the best. Quality, knows what he is talking about, honest. Outstanding!"
Scott F.

"Josh & D hands down good guys and if you want your stuff done right this is the place to take it. Thanks guys for all the help you have given me in my G8 and most of all the friendship that we have."
Eric William M.

"Took my project truck to Josh and crew when my wiring harness guy (another place) SCREWED up. At that point, it was a lost cause and a money pit. Nothing was communicating or working correctly. I was ready to give up. My truck isn't some top notch show piece...so getting someone to see my vision is rough sometimes. Josh took the time to talk about my vision and then set out to make it happen. He gave me back my project in perfect running order. MUCH better results from the Spartan guys than I could have hoped for. Honest, knowledgable, friendly, funny, and easy to talk to (once you get him on the phone). THIS is where any future projects go first from now on. Can't thank these guys enough."
Douglas C.

"Had my entire car built here by Josh. Cam install & tune, the works. Couldnt have been happier and we'll never go anywhere else. They do EXCELLENT work and are all really cool guys. They have a reputation as being one of the best in the Atlanta area and that is 100% deserved."
Trey C.

"Josh built my camaro from the ground up a few years ago. Ive been kicking a## on the street ever since. Cool guy great builder will do business with again."
Henry M.

"Just had my G8GT tuned by Josh. Car is a totally different animal now. Top notch work!"
Tom P.

"Took My Car In Tuesday for Headers, CAI & Tune. I'm More Than 100% Satisfied. Not 1 Complaint. Talking With Josh, He's A Real Cool Dude Man Looking to Develop a Friendship with his Customers. WONT TAKE MY CAR ANYWHERE ELSE. THANKS SPARTAN"
Da K.

"Took my '14 Camaro up to Spartan four weeks ago for a complete suspension upgrade and couldn't be any happier. Took it to Road Atlanta the very next day for a track day and it was a night and day difference. Communication was excellent, the price was below what others were trying to charge me for the same job with more time needed for the installation. I plan on doing many more mods to my car and Spartan is where im taking it to get those mods installed!"
