Steeda "Stop the Hop" Street Starter kits help you eliminate wheel hop and stay within your budget. These kits contain the best three components to rid your Mustang of this menace, provide the fundamental foundation for ultimate traction and suspension compliance, and address the issues with factory IRS subframe mounting. Want to "Stop the Hop"? Get a Steeda Street Starter kit. Kit components: * IRS subframe alignment dowel kit -- Fills the factory bolt hole voids with CNC-machined Delrin® inserts that will square up the rear subframe to the chassis and limit side-to-side and front-to-back movement of the subframe that is present under hard acceleration and braking. * IRS subframe bushing support system -- Patented 8-piece kit designed and made in-house from billet 6061 aluminum and features stainless steel hardware. Fills all the factory voids in the IRS subframe mounting locations, preventing up-and-down movements of the subframe. * IRS subframe support braces -- Made in-house from chromoly steel, these 5-point braces with a simple bolt-in design support the factory subframe by directly tying it into the chassis at key mounting locations, utilizing factory mounting locations on the factory frame. They support the front factory mount and the lower control arm mount as well. Kit benefits: * Eliminate wheel hop while not increasing NVH * Eliminate subframe movement * Simple installation * Squares subframe to the chassis * No permanent modifications

One of the most effective ways to improve the stiffness and handling of your vehicle is to box the factory chassis. Hellwig Frame FX kits makes it easy for you. Rather than taking considerable time with measuring, cutting, and fitting steel panels these kits simplify the process effectively. Some vehicles have an open C-channel chassis that's only 3 in. wide at the top and bottom. This design is inherently weak in handling torsion and marginal in bending. Frame FX kits double the width of the tension side of the frame rail and close the area for dramatic increases in torsional and bending stiffness. They're comprised of 14 pre-cut 10-gauge steel panels matching the thickness of the factory frame--and fit into the weak points of the factory chassis. Hellwig engineered another panel that adds an extra mount to tie the floor to the chassis, furnishing even more strength to the entire car. In addition, brackets are provided to mount the transmission crossmember, with enough adjustment to accommodate nearly any drivetrain configuration. The increased strength via Hellwig Frame FX kits results in improved handling and ride quality, while retaining the factory chassis and mounting points.

The 1967-69 F-body was designed in an era when high performance driving and modern tire technology weren't as prevalent. Their unibody chassis, while innovative at the time, can flex and twist under stress, particularly when cornering aggressively or accelerating hard. QA1's bolt-on subframe connectors offer a simple and effective solution to this common issue. They tackle the flex issue by increasing frame rigidity, leading to a significant improvement in handling performance—especially during cornering, acceleration, and braking. The tubular design connects the front Camaro/Firebird subframe to the rear subframe, providing additional structural support and stiffness to the chassis. Additional details: * Included solid body mounts and hardware further reduce chassis flex. Their aluminum construction offers a noise-free alternative to polyurethane. * Thoughtful design: The QA1 subframe connector contours to follow the body lines for a factory-like look without sacrificing ground clearance. * Easy bolt-in installation makes the upgrade hassle-free. * Fitment notes: Does not fit convertibles.
