Speedtech Performance USA frame brace kits prevent the sloppy, unpredictable feel of a weak body frame. You can increase rigidity by linking these braces to the strong structural undersides of your chassis. The braces are constructed from 1.5 in. DOM steel tubing that's computer designed, machined, and CNC-bent for consistent fitment. Speedtech Performance brace kits offer the reinforcement your race chassis demands.

Looking for the ultimate set of performance spindles? Speedtech Performance AFX Performance spindles are here to get the job done! GM musclecars are known for having poor geometry from the factory. They rode relatively smooth and did well in straight line drag race situations, but high-speed cornering was less of a consideration in their designs. With today's technology, correcting these issues with control arms helps, but is only part of the equation. Speedtech and ATS have taken an entirely new approach to improving the less-than-optimal factory suspensions of the A, F, X, G and B body platforms by scratch-designing the focal point of the steering and suspension geometry: the front spindles. They will drop your ride height 1 in. for a more aggressive stance and lower center of gravity. Relocated steering arm mounting points are custom-designed for each individual vehicle to improve Ackerman and bring bump-steer numbers down to nearly zero. The spindles feature a Corvette ZR1 sealed, maintenance-free hub; it's heavy-duty, and the large bearing pack offers a stronger load capacity--able to handle the abuse of street and track driving. Speedtech Performance AFX Performance spindles and the ZR1 hub combination do not alter the factory track width or bolt pattern, allowing standard wheel fitment. Brake mounting is based on the C5/C6 Corvette and accepts factory Corvette brakes or packages from multiple manufacturers, including Baer, Wilwood, and others.

Speedtech Performance USA billet body mounts solve those problems you may be having with the original body mounts on your car. Worn rubber body mounts enhance body roll and give handling a sloppy feel. If you're replacing your suspension components, these body mounts with their solid aluminum construction are ideal. They're CAD-designed and CNC-machined in-house to exact tolerances from T6061-T6 billet aluminum and then anodized black for maximum durability. Speedtech Performance USA billet body mounts also include all Grade 8 hardware needed for installation.

Replacing upper control arms is one of the quickest ways to enhance the handling performance of your vehicle. Speedtech Performance USA tubular upper control arms are designed with improved geometry and Delrin bushings to help your car navigate the curves and corners. They're lighter, so the unsprung weight aids in acceleration. Heavy-duty ball joints and hardware are included to ensure long life under extreme conditions. The control arms are CAD-designed and constructed from CNC mandrel-bent 1.25 in. diameter and .120 in. wall DOM tubing. All components are laser-cut and CNC-machined for exact tolerances, TIG-welded, and then powdercoated gloss black. Speedtech tubular upper control arms come assembled complete with 304 stainless steel cross shafts, greaseable Acetron GP Delrin- type bushings, performance ball joints (including forged housings), full spherical pins and CV-style dust boots, urethane bump stops, and Grade 8 mounting hardware.

Offered as a high performance direct replacement for the flimsy and cumbersome factory sleeves, Speedtech Performance USA billet tie rod sleeves are designed to eliminate flex and the possibility of jumping threads. They are easier to adjust and they protect the tie rods from the elements--which typically cause factory sleeves to rust. Speedtech sleeves are CAD-designed and CNC-machined in-house, assuring quality and consistency in every set, and then black powdercoated for protection.

The ability to properly set up the chassis and tune to individual track conditions is one of the basic fundamentals for achieving low lap times. Adjustable spring rate, ride height, and shock dampening is a vital part of that tuning process. True coilover shocks allow for all these to be done in one easily adjustable package, while avoiding issues where other coil and shock combinations fall short. Speedtech Performance USA created the complete Chicane coilover kit for a variety of Chevrolet, Buick, Oldsmobile, and Pontiac cars from the 1960s and '70s—so that coilover shocks can be installed and put to use in your factory frame! Designed to be welded in place of the factory upper shock mount, these kits convert the factory shock mount to a double sheer coilover mount for use with coilovers with a T-bar lower mount. Unlike other kits on the market, being able to make tuning adjustments without removing any components from the vehicle was a primary design goal for the Chicane coilover kit. It allows easy on-car adjustment of ride height, rebound, and compression. Since the factory upper control arm mounting bracket remains unaltered, engine removal is not a requirement for installation. Welding of the Chicane coilover kit is basic and straightforward—and can be completed by a certified welder within an hour. The complete kit includes QA1 double adjustable coilover shocks. Complete Chicane kit includes: * 2 weld-in double sheer laser-cut cages with formed stiffener plate * Coilover spacer * QA1 adjustable coilover shocks * Spanner wrench and thrust bearings * All necessary hardware

Speedtech Performance USA rear suspension systems utilize Articulate technology on the upper and lower trailing arms to rotate laterally while the suspension travels through its normal range of motion. This greatly reduces bind and maintains better geometric curves. Delrin bushings throughout eliminate the flex of rubber and squeak of urethane. Speedtech's chassis-mount adjustable sway bar allows the bar to work at its full potential. With the available added feature of a bolt-in true coilover shock conversion, you'll be able to tune your suspension to reach its max performance! The base rear suspension systems include Articulate adjustable no-bind upper and lower trailing arms, Delrin bushings, adjustable 1 in. tubular rear sway bar, Grade 8 hardware, and instructions. They feature QA1 double adjustable coilover shocks, allowing for 19 setting positions for both compression and rebound settings—that's a total of 361 different valving combinations! Precision-machined PTFE/bronze-wrapped pistons on 5/8 in. hard chrome plated rods are encased in clear anodized, lightweight aluminum housings. Left-hand threads avoid shock separation when adjusting your ride height. Speedtech systems are available for a variety of vehicle applications from the 1960s and '70s.
