All Your Custom Tuning and Race Support Needs!

555 Motorsports is a shop I started in 2006 with the focus of tuning and performance in mind. I started in Washington, after that I relocated to my home and moved my operations to Chicago. Once out there I continued tuning in the area for local shops and traveling all over the US. 555 Motorsports has always been a one-person set-up. I, Mathew Cater have been working to ensure the customers get the best tuning solutions for their cars and performance.

In my experience I have tuned for many shops and now we have a facility we share with URW, which houses our Mustang Dyno, (500 SE AWD).


Some of the Services we offer include:

Custom Dyno Tuning

Remote Tuning 

Driver Coaching

Data Analysis

Track Support ​
