TB Performance chassis braces were one of the first things I did my my Fiesta ST. Why? Because: 1) They're relatively inexpensive, 2) they're easy to install, and 3) they won't void your warranty (if you're worried about that sort of thing). If you're a new owner of a FiST, these allow you to get even more response & performance out of the already aggressive chassis WITHOUT putting any additional strain through the engine or drivetrain. And if you've had your FiST for a while, even better, because it's gonna spark-up the driving experience, tighten up response, and remind you of how rad your car actually is & why you bought it in the first place lol.
TB TRACTION BAR /// FIESTA ST
The TB Traction Bar will...
1) Reduce wheel-hop.
2) Reduce torque-steer.
3) Improve cornering.
It does this by tying together THE DRIVER + PASSENGER A-ARMS under the chassis, thus strengthening & bracing the front suspension… and eliminating deflection.
WHEEL HOP: Wheel-hop occurs when you launch a car, and there is a deflection in the A-arms. Grippy surfaces can magnify wheel-hop, but the premise is: On launch, the front bushings in the A-arms deflect downward, and the rears deflect upward - violently & abruptly. And it creates a rhythmic, uncontrolled up/down banging, known as ‘hop’. But by tying together the driver & passenger A-arms, the system is strengthened exponentially, and deflection is hugely reduced. The same principle applies for torque steer.
TORQUE STEER: Torque steer is a general area of complaint with front-wheel-drive cars, and the TB Traction Bar really assists in nullifying the problem. One of the main causes of torque steer - is when the A-arms shift under the initial high load of power/boost being delivered to the front wheels. It’s much like wheel-hop, but the deflection is horizontal rather than vertical. With the TB Traction Bar reinforcing this section of the vehicle, it prevents the deflection of the A-arms.
CORNERING: Last but definitely not least, is lateral grip - aka cornering. During aggressive cornering, the A-arms flex side-to-side under load. Because the TB Traction Bar is preventing that deflection, that lateral flex is strong-armed… and kept in check. The result is better lateral grip, and a more responsive car.

And BTW - if 'who you buy from' matters just as much as 'what you're buying'.... let it be known that Danny Check of TB, is one of the most solid dudes you'll ever find in this industry. He's born & raised near San Diego, totally down-to-earth, a helluva rock-climber, and super passionate about the daily-lifestyle side of car culture & ripping around in fun cars. He will not put a part into production if it does not improve the vehicle.
