A Mustang you could order from any Ford dealer
The TdF Mustang was a Ford dealer option with a Holman Moody handling package. Ford approved the project and gave it a dealer code, so a TdF could be ordered through any Ford dealer. The car went to Holman Moody for the parts to be installed, or the dealer installed them.
Holman Moody's hmPerformance designed the handling package, and I designed its front and rear sway bars as part of the design team, before I founded Atrick Design. In Holman Moody's words: "Fully adjustable suspension allowing adjustments for road race, rally, autocross or commute without changing any components."
Adjustable without changing parts
Both bars are splined, with separate arms that fit onto the ends of the bar. Each arm has a row of holes. Moving the end link to a different hole changes how stiff the bar acts, which shifts the balance of grip between the front and rear of the car. That adjustment is part of what lets the suspension go from road race to commute without changing parts.
I did the routing and the calculations, working out the bar stiffness at each hole and balancing front to rear across the settings with a calculator I built myself.
1.18 g on street tires
Holman Moody reported the TdF Mustang cornering at 1.18 g in testing at VIR and Lime Rock. The unexpected part is the tires: that was on street tires, not track tires.
I also designed sway bars for Holman Moody's S650 Mustang. The rear is splined like the TdF bars. The front is a bent bar, designed with a 3D scan as a reference.
★★★★★“We used Atrick several times now for prototyping and engineering work, as well as electronic design work. Each time, the product was exactly as needed, and performed perfectly. One of our higher profile projects was to engineer, prototype and test a suspension for a track car, which had a lot of corporate eyes on it. The end result was a car that exceeded anyones expectations, and ultimately wound up in production and available at any dealer. To say this was a success is an understatement.
In another project, we needed to develop a proof of concept which included mechanical and electrical design work, with complex components and programming. The prototype was a success and hopefully this will also go in to production. If your company needs prototyping, product development and engineering expertise, Jay and Atrick is the only place you need to call. You will find highly experienced and skilled folks that will absolutely deliver the best product and on time.”
