Collection: Antigravity Batteries

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.

Everything seems in good condition and good quality, appreciate the help from brian for all my questions and to setup the shipping to canada

Hello, these coil overs are great. Very good quality and look great! Thank you!!

Great product shipped out fast easy install.

Brian R. was extremely helpful and spent a good amount of time answering my questions about switching to coilovers. He was a wealth of knowledge and made the purchasing and installation process very easy.

He is so genuine, he helped me out on which parts I should get for my wife’s ‘16 Veloster Turbo. Parts came super fast and was packaged beautifully

Havn't installed yet so I cannot speak to the parts, as they get some run time I will review. Brian at FI was amesome though all through the process. Had questions prior to ordering and he went above and beyond in providing me with answers. After I ordered the parts he called a few days later appologizing for not reaching out sooner, which is crazy cool since country was dealing with hurricane devestation. I didnt expect to recieve parts for a while however they all showed up in about a week. I will def do buisiness with them again and recommend them to anyone in the future.

I bought Silvers Neomax coilovers with aero spring rates (14k/12k) for my track car. The quality of them is great. Install was straight forward and they are easy to adjust and tune as needed. Real happy with them so far and I think they're the best value out there in coilovers. Great price without a sacrifice in quality or performance. Also Brian at FI PERFORMANCE has been great in responding to all of my questions. Has been a great experience so far.

Quality part.

Brian answered every time I called and answered all the questions

Excellent coilovers
The best customer service from Brian
Highly recommended

Works great it stiffens up the rear end and no more wheel hop best diff brace out of all I have used in the past, money well spent.
