From performance builds that turn heads to reliable repairs that keep you rolling — RCS Motorsports is where your next ride comes to life.
RCS Motorsports was born from a simple belief: your vehicle should reflect the way you drive. Located in the heart of Rubicon, Wisconsin, we've spent over a decade turning stock rides into machines that perform as good as they look.
Whether it's a weekend canyon carver, a daily driver that needs honest service, or a full custom build from the ground up — we treat every project with the same level of care and craftsmanship.
Our shop is your shop. No upselling, no jargon, no surprises. Just skilled hands and a genuine love for what we do.
From routine maintenance to full performance builds, we cover everything that keeps you on the road and coming back for more.
Full engine builds, turbo and supercharger installations, ECU tuning, and aftermarket upgrades that extract every ounce of potential from your vehicle.
Engine swaps, rebuilds, transmission service, clutch replacements, and driveline work — precision-built and backed by experience.
Coilovers, sway bars, control arms, alignment, and complete suspension setups tailored to your driving style — street, track, or off-road.
Brake service, oil changes, diagnostics, cooling systems, and everything in between. Reliable transportation shouldn't be complicated.
Custom exhaust systems, fabrication, welding, and unique modifications that make your vehicle one of a kind — no two builds the same.
Dyno-tested tuning, fuel system upgrades, intake and exhaust optimization, and bespoke calibrations for maximum power and reliability.
They took my daily driver and turned it into something I actually look forward to driving every day. Honest pricing and incredible work.
Best shop in the area, hands down. They explained everything they were doing, showed me the old parts, and the car runs better than ever.
I brought my project car in as a dream and walked out with something that exceeded every expectation. These guys live and breathe this stuff.
