![]() ![]() The strength of the new rearend and internals combine with the adjustability of the new S197 suspension components to open up a whole new world of performance. The finished product provides LaSala with more consistency and adjustability - not to mention safety - than he ever had with the factory suspension configuration. The shock is going to control how long it takes to reach that point.” The car at ride height is a certain height, and then a car at extension is at a certain height. I’d say suspension adjustments are more of a big change, and then small changes will be made in the shocks. We can control the amount of time it takes to get to the extension by the shock adjustment. Small adjustments will be more in the shock we have a shock travel sensor on there, so we can see how long it takes the shock to reach extension. “The big adjustments really show you if you’re going in the right direction or not. “You can watch the shocks and everything based off of your run, overlaid on your regular datalog, so your time, like how long you’ve been on the transbrake, how much boost and RPM, you see it all together. He is past making significant changes, trying to dial it in based on what he’s learned so far. He is confident in the changes because of his data acquisition capabilities, as the car is equipped with a MoTec M150 ECU. After that, it’s actually moving over,” says LaSala.Īs you might imagine, this is not good when you’re running mid-7-second elapsed times at 180-plus mph. Its job is to keep the differential centered in the car, but the problem is it’s only centered at ride height and maybe an inch up and an inch down, relative to the center. With the full extension of the car, the diff would probably move almost an inch from side to side because of the Panhard bar. As the car goes up and down, the diff moves side to side. “We removed the factory Panhard bar - it isn’t exactly good for a car with extension because the Panhard bar mounts to the frame on one side, and then it’s mounted to the diff on the other. Both uppers and lowers are constructed from chromoly tubing and high-quality Heim joints.Īlthough in factory form, the S197 suspension can be made to handle quite admirably, even at the dragstrip, when you step up to the level of LaSala’s machine, there is one critical issue - the Panhard bar. and offers several mounting positions, similar to the housing-side mount. The upper control arm body-side bracket is from Racecraft, Inc. Team Z Motorsports delivered the fabricated housing without the lower control arm mounting points Lamana designed his own lower control arm mounting brackets to work with this specific vehicle for a couple of reasons. These include moving the rear shocks into an advantageous location, switching the dampers to a set of double-adjustable units at all four corners, completely replacing the front suspension, a new 9-inch rearend housing from Team Z Motorsports, and more. Optimizing the S197 suspension for somewhere around 2,000 wheel horsepower on radials involved many changes. It’s tuned by Jay Meagher at Real Street Performance (Brett’s place of employment) and runs on One Ethanol fuel. ![]() With the help of Don Lamana at ProFab Performance in Hudson, Florida, LaSala mapped out a plan to change the car up for the 2021 season.įor reference, the car features a stock-displacement, Fast Forward Race Engines-built Coyote featuring Manley Performance internals, GT350 cylinder heads, custom cams, Plazmaman billet intake manifold, Plazmaman air-to-air intercooler, and twin 7675 Precision turbos in a custom turbo kit. He recently dove headfirst into updating the S197 suspension and altering the traditional three-link geometry to get a better handle on the car. His transmission-building skills have served him well in the community as he’s known as one of the go-to guys for making vast performance improvements to the 6R80 transmission.Īs he has stepped up the Snot Rocket’s efficiency at the track, he’s made incremental improvements to the car overall. His “Snot Rocket” twin-turbo S197 has been at the forefront of Coyote performance for many years. ![]() Florida racer Brett LaSala is well-known in the Mustang community. As the racer steps up a car’s horsepower capabilities it’s wise to start improving the suspension to match. For a racer, exploiting every last possible area for performance improvement is a rite of passage. ![]()
