Professional kinematic analysis in your browser. Calculate camber gain, roll centre migration, anti-dive, bump steer and spring rates — then export a branded PDF report. Built by a motorsport engineer, using the same kinematic theory as professional race teams.
No CAD software required. No $20,000 Adams licence. Just open the browser and start calculating.
Camber gain, roll centre height and migration, instant centre location, track change and toe change across full wheel travel. Live curves update as you type.
Side-view instant centre calculation from forward and rearward arm pickup heights. Anti-dive, anti-squat and anti-lift percentages with animated side-view diagram.
Exact bump steer calculation from tie rod inner and outer pivot positions. Toe change vs travel curve with length error analysis. Target: <0.05° per 10mm.
Motion ratio from pushrod/rocker geometry. Wheel rate, ride frequency, critical damping coefficient. Damper force targets at 5 shaft velocities.
Formula Student, GT3, road car and rally presets to start from. Load any preset and immediately see how a real geometry package looks before entering your own data.
Two-page branded engineering report covering all modules — geometry summary, anti-geometry, tie rod analysis, spring spec and full damper force table.
Save your suspension setup and reload it any time. Compare two geometry configurations side by side — ideal for iterating between design proposals or qualifying setups.
No subscription required. The full calculator and PDF export are free. Pro unlocks session management, compare mode and priority support.
All prices exclude VAT. Annual billing available at 2 months free.
ChassisCalc was built out of frustration. The professional suspension tools cost €15,000 a year and require a week of training. The free alternatives are Excel sheets from 2004.
My master's thesis was on suspension systems for Formula Student race cars. I understand what engineers actually need during a design iteration — fast geometry feedback, clear visuals, and a report they can hand to a client or team principal.
This tool is that. No bloat, no enterprise sales process, no six-figure invoice. Just the calculation you need, in your browser, in seconds.
