Suspension Geometry Ninja
Vehicle geometry and design simplified.
Nail your suspension geometry — hit every target and see exactly what it does through the full range of travel — then export it to CAD to build. The hard, iterative part of designing a suspension that actually handles, done quickly instead of hundreds of CAD passes.

See what it's actually doing
Every parameter graphed through the full range of travel — camber, bump steer, roll center, anti-dive, instant centers, motion ratios and more — next to a live, full-vehicle 3D view you spin and zoom. Not flat front-and-rear diagrams, and not a wall of numbers to decode. You watch the suspension move.
Hit your targets
Set your targets and tolerances — roll center, camber gain, bump steer, scrub, trail, KPI, caster, anti-dive and squat — then Geometry Ninja moves the pivots to reach them. Miss any and it flags exactly which, and how to open up the tolerances. Work that takes hundreds of CAD iterations, done for you.
Design what you can actually build
Using an OEM upright or off-the-shelf arms with fixed lengths? Lock the points you can't change, and push a link's exact length onto the chassis or upright side so everything else moves to fit. SGN designs around the off-the-shelf parts you're really using.
Sway bars, all the way to the wheel
Real bend-by-bend bar geometry, with the bar's motion ratio and the suspension's combined — so you see the rate that actually reaches the wheel and how it shifts your balance. The step nearly every affordable tool skips. Export the 3D bar path straight to your bender.
Into your real vehicle
Import your CAD in 3D and see exactly where the suspension lands in the car before finalizing. Export every pivot, link line, and the full sway-bar routing to IGES — into SolidWorks or any CAD, ready to build.
Fast, and no sorcery
A full 3D kinematic sweep solves in seconds or less. Every instant center is cross-checked by two independent methods and scored, so broken or flipped geometry gets flagged, never silently printed. The math is textbook — SGN just runs it right and shows the work.
Every feature here came from a real build. SGN grew out of designing a cramped suspension — each tool exists because it solved a problem in the workflow, first for me, then for anyone building the same way.
