MacPherson, Double-Wishbone Front Suspension Setups Explained: Video

We all know how easy it is to play the role of “armchair quarterback,” regurgitating bits of wisdom compiled from half a dozen things we’ve “heard” or “read” as though they’re obvious, almost self-evident truths.

Now, the folks at DRIVE are hard at-work ensuring that we seldom have an excuse, with a new video series aimed at making us all comparatively well-versed in how automotive systems are engineered. The video above covers the basics of front suspension setups, exploring the geometries of both the popular MacPherson strut, and the somewhat-more-scarce double-wishbone.

For those of you considering dropping your Mustang’s center-of-gravity, this explanation of front suspension systems is indispensable.

The 2015 Ford Mustang uses a double-ball-joint MacPherson strut suspension, meaning that all of the talk about the double-wishbone, a.k.a. SLA (short-long arm) doesn’t really apply to current owners, but it’s a fascinating and worthwhile explanation nonetheless. And, regardless of front suspension type, this video teaches us is precisely why lowering a vehicle’s ride height mightn’t always necessarily be a no-brainer. Filip Trojanek – founder and owner of Cortex Racing, and our teacher through this crash course in front suspension geometry – explains that in order to correct for any fundamental changes to geometry resulting from lowering the ride height, his company goes so far as to fit special ball joints and other components to maintain a scrub radius and camber range equal to or better than stock.
