StringAlignPro

String Align Pro turns the proven string-box method into a fast, accurate alignment tool you can use right at the car — no laptop, no rig, no internet. Enter the distances you measure from the string to the front and rear of each rim, and String Align Pro does the geometry for you: per-wheel toe, total toe per axle, and the rear thrust angle relative to the car's chassis centreline. Because it works from the centreline, it reveals crabbing that front-and-rear-only numbers can hide — so the car runs true, not just "aligned." KEY FEATURES - Toe, total toe and thrust angle, calculated from simple rim measurements - Thrust angle referenced to the chassis centreline - Camber recorded per corner - Work in your units: enter distances in millimetres or inches; read toe in mm, inches or degrees - Before & After: capture a baseline, make changes, compare side by side - Clean PDF reports in your chosen units — for the car's file or the customer - Save jobs by name and reopen them any time - Fully offline — everything runs and stays on your device - No account, no sign-up, no tracking - Universal: works on iPhone and iPad BUILT FOR THE PADDOCK Whether you're setting up a track-day car in the garage or making changes between sessions, String Align Pro keeps the numbers you act on the same as the numbers you measured — and keeps a record you can share. IMPORTANT String Align Pro provides guidance based on the measurements you enter. Always verify your inputs and check results against your own engineering judgement and the vehicle manufacturer's specification. Wheel alignment affects vehicle handling and safety — setup decisions are yours. Published by RaceTracs Ltd.
