“Simplify, then add lightness.”
Rush SR
Pro speed. Affordable seat time. Finally.
The Real Cost of Racing
We got tired of watching friends blow their budgets on cars they couldn’t afford to run. So we built something different.
3-Year Total Cost of Ownership
| Used Prototype | GT Car | Rush SR | |
|---|---|---|---|
| Up-front cost | $45–130k | $80–150k | $49k–59k |
| Annual running costs | $30–100k | $60–200k | $10–14k |
| Typical crash repair | $15–80k | $10–50k | $3–5k |
| 3-Year Total (excluding car resale) | $150k-500k+ | $270k-800k+ | $79k–101k |
*Running costs include tires, brakes, rebuilds, consumables, transport, entry fees, and one minor incident repair per year. The “Typical crash repair” row shows a typical incident cost for comparison — it is already embedded in the $10–14k annual figure, not added separately to the 3-year total.
Drive Like a Pro
We race these cars ourselves. That’s why they feel like weapons, not appliances.
Paddle-Shift Racing
Six-speed pneumatic sequential with no-lift upshifts and auto-blip downshifts. Left paddle down, right paddle up. The clutch is only for standing starts.
150 HP at 11,800 RPM
The Suzuki GSX-S 1000cc engine screams to nearly 12,000 RPM. At 1,130 lbs, that’s 0-60 in 3.3 seconds and 150+ mph.
No Driver Aids
No traction control. No ABS. RWD. Like a real race car should be—just raw skill and mechanical grip. You’re in control, not a computer.
Real Driving, Not Aero Dependency
Unlike downforce-dependent prototypes, the Rush SR rewards driver skill. Trail-brake, rotate, get sideways on exit. Every driving style is fast.
Pure Mechanical Connection
Manual rack-and-pinion steering with no power assist. Quick-release wheel. Every input transfers directly to the wheels—you feel everything.
Center Seating
Sit on the racing line. The central driving position—same layout as F1 and McLaren supercars—gives you perfect visibility through apex and exit.
Technical Specifications
Purpose-built for competitive racing. Every spec optimized for performance, reliability, and value.

Where to Race
A race car is only as good as the racing it gets you into. The Rush SR opens doors.
Rush Spec Series
Our dedicated spec series runs with GridLife at tracks across the country. Same car, same rules—the racing is close and the competition is real.
Sanctioned Everywhere
The Rush SR is legal in NASA, SCCA, SVRA, XSR, and more. Show up to nearly any racing organization and you’ve got a place on grid.
Meet the Grid
Real drivers. Real stories. This is who you'll be racing with.
Wrench on It Yourself
We designed this car for a two-car garage and a basic tool set. Because that’s what we had when we started.
Home Garage Friendly
No lift required. No specialized tools. Change your own brakes, swap your own bodywork, do your own setup—and get back to the track.
Quick-Release Everything
Front and rear clips pop off in minutes with Aerocatch latches. Full engine and suspension access without fighting fasteners.
Parts When You Need Them
All parts ship domestically – order Monday, install Friday. Compare that to waiting six weeks for a container from Europe.
OEM Parts Availability
Suzuki engine means real parts availability—not unobtanium from a defunct manufacturer. Gaskets, bearings, seals: on the shelf, priced for motorcycles.

Built to Protect
We race these cars hard. So we built them to keep us safe when things go wrong.
Exceeds Requirements
Full chromoly roll cage exceeds NASA and SCCA safety requirements. Side intrusion bars, diagonal bracing, and proper triangulation throughout.
Trident Rollbar
For the ultimate in cockpit protection, the optional Trident rollbar adds a triple-bar structure around the driver. Purpose-built for open-cockpit racing.
Real Crash Structures
Front and rear crumple zones absorb impact energy before it reaches you. The chassis deforms in the right places while keeping the survival cell intact.
Sanctioning Approved
Legal in NASA, SCCA, SVRA, and more—meeting or exceeding their safety requirements.
Modern Safety Equipment
- FIA-approved fuel cell with bladder and foam
- 6-point harness mounting points properly positioned
- HANS-compatible seat and harness geometry
- Fire suppression system available
- Quick-release steering wheel for rapid egress
- Deep sidepod nerf bars with anti-intrusion panels
