Tuning group fifteen52 introduced the TrackSTer, a performance concept based on the Ford Focus ST, at the Chicago Auto Show. The TrackSTer is included in the team-up between Ford, Los Angeles-based fifteen52, and racer Ken Block named Project ST. Two other tuned Focuses will debut this year as part of Project ST.
The TrackSTer is meant to add track-ready performance while still being laid-back enough to be used on the streets. It features a short-throw shifter and performance exhaust from Ford Racing.
It also gets a more powerful clutch, bigger brakes, and Quaife limited-slip differential that are all developed for the Focus ST-R race car program. Aside from that, fifteen52 enhanced the Focus ST with forged internal components, a reflashed engine computer, and a bigger intercooler from Monotune.
In a statement, racing driver Ken Block said that collaborating with fifteen52 for this project was an “obvious choice” since both Ford Racing and Mountune have come up with “a potent package” that combines on-road performance with on-track performance.
It’s not clear if fifteen52 is planning to get their TrackSTer on sale, or if these parts will simply be sold for customers to install on their own.
Even if the TrackSTer was introduced at the show, it won’t stay on display during the Chicago auto show’s public days. The standard Ford Focus ST is powered by a 2.0-liter turbo-four engine with 252 hp.
It makes use of a torque-vectoring system to suppress under steer or wheel spin by applying the front brakes. However, the limited-slip differential may cancel out the need for that electronic system.
