Brian at FI Performance always goes above and beyond to take care of customers. I am a repeat customer and will continue to use them for all my needs. Thanks again Brian, amazing as always!

Exactly what I needed for my lowered C5. Full range of adjustment and quality made product.

Got a great product. In a very timely manner very happy

Great experience, order got messed up and Brian made sure to get it fixed and kept me up to date by texting me.

Exactly what I needed and had it next day

Customer service was great. Order shipped quick. Great value and the change to the car was better than expected. Wife no longer braces herself for the expansion joints and other Ohio road issues.

Brian was AWESOME to deal with, I changed my mind a few times on what I wanted to do with my c6z.. You can go down an endless rabbit hole when you get into these cars “while I’m in there “He was right there with updating pricing and I couldn’t ask for more.. Parts are parts and they will fail but it’s the service that sets the bar for a big purchase.. I haven’t driven the setup yet as it’s still being built but I’m sure he a phone call away to get it sorted..

Great customer service as always. Was on my doorstep within 48 hrs.

High quality parts with installation pics to come

Great support team helped me get the parts needed and got my order within the week.

Balancer was exactly what I needed. Everything as described and fast shipping. Thanks guys

Team went above and beyond to locate the part needed to get my can back on the road asap.

I finally got to install the intake which literally took 10 minutes. The power and launch difference was insane! You can hear the turbos spooling a lot better as well. I’m amazed by the difference just from the intake

Great product and communication.

I went with the super low, extended rear shocks , Swift 9/7k upgrade and absolutely love the stance and how the truck rides. It’s tight in the corners , smooth driving down the hwy and not bouncy at all. Thanks to Brian for getting me set up.
