Free · Designed for iPad. Not verified for macOS.

Plan your dream car build. 44 platforms, real parts, real prices, real WHP numbers. Free forever. StageUp is the free car modification build creator for enthusiasts. Pick your platform, select real aftermarket parts, and watch your estimated wheel horsepower update in real time. PLAN YOUR BUILD Browse 44 car platforms across 10 makes — BMW, Honda, Nissan, Toyota, Ford, Subaru, VW/Audi, Hyundai/Kia/Genesis, Dodge, and Chevrolet. Select parts across 16+ mod categories, including tunes, intakes, downpipes, turbos, exhaust, suspension, brakes, wheels, and more. Every product has real retail pricing and verified WHP gains. TRACK YOUR BUDGET Set a budget for each build and see exactly how much you've spent. Products that push you over budget are flagged automatically so you can plan smarter. SEE YOUR POWER Toggle between 93 octane, E30, E50, and E70+ ethanol to see how fuel affects your power output. The animated WHP display shows exactly where your build falls — from mild bolt-ons to a full-built race car. VIN SCANNER Scan your VIN with your camera or enter it manually. StageUp auto-detects your platform so you can start building immediately. COMMUNITY Publish your build to the gallery. Browse what others are building. Like builds, clone them as templates, and write part reviews with verified install badges. Request new parts and brands — the community votes, we research.
