Stock 1979 Ford Mustang 4-Link Suspension Geometry & Anti-Squat - Performance Trends

This is a screenshot from the Performance Trends Inc. '4 Link' suspension analysis software, showing a saved project titled 'STOCK 79 MUSTANG' (registered to Douglas C. Rahn). The screen displays a side-profile schematic of a Mustang with its rear 4-link suspension geometry drawn in, including link lines converging to a calculated instant center. Key computed values shown are: Instant Center Length 34.3 inches, Instant Center Height 13.2 inches, and Anti-Squat 174.7%, with suspension type identified as '4 Link'. Below the diagram, driveline angles are reported: Pinion Angle 2.00, Trans Yoke Movement .00, and Driveshaft Angle 2.00. A 'Holes Used' table lists bracket hole coordinates: Top Bracket rear (axle) #1 0" x 19.5" and front (chassis) #1 7.5" x 18.13"; Bottom Bracket rear #1 0" x 10.38" and front #1 18" x 11.88". A 'Show Dynamic Changes' panel (set to No) offers inputs for Rear Spring Compression and Front End Rise. A reader can learn the stock 1979 Mustang 4-link geometry, its resulting instant center location, anti-squat percentage, and driveline angles as modeled in this software.
