RS Engineering was founded with a simple goal in mind: make the Mazda RX7 run faster and more reliably at the track without sacrificing any of its street manners. Each of our components are built to be as functional, efficient, and cost-effective as possible.

Our Test Platform

All RS Engineering parts are tested on our highly-modified 1994 Mazda RX7 R2. Featuring a seven liter (427 cubic inch) LS7 motor, 285-series DOT-R tires and 4-pot calipers with Hawk DTC-70 pads, this street car runs lap times competitive with purpose-built race cars. Capable of generating over 1.2 lateral G on a typical lap, our platform is the optimum way to test and perfect all of our performance upgrades. The vehicle is fully instrumented with on-board telemetry (GPS and accelerometer) and real-time data acquisition.

Our Methodology

We run at a number of local tracks including Laguna Seca and Infineon Raceway which provide us with perfect environments to push our desgins to the limit. (The image at the top of the page is our car carving down Laguna's world-famous "Corkscrew" turn.) Our platform is run consistently for multiple back-to-back laps to simulate the most extreme track or street conditions. In addition to logging lap times and grip limits we also employ probe-type thermocouples, temperature paint, and other tools to quantitatively measure the performance and durability of our performance parts.
