Steeda Stop the Hop Street Starter Kits

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

Steeda Hardcore Differential Support Brackets

Steeda Hardcore differential support brackets are engineered to dramatically strengthen the factory independent rear suspension by locking the differential in place and redistributing load away from the vulnerable front mounting ears. Developed to prevent housing damage under hard launches, these heavy duty, bolt in brackets reduce wheel hop, minimize pinion rise, and significantly limit differential movement so more power is transferred to the ground instead of being lost through bushing deflection. Steeda's triple shear mounting configuration eliminates the factory single shear weakness, increasing load capacity and durability, while upgraded hardware adds an extra margin of safety for high traction tires and aggressive driving. Ideal for performance focused builds, Steeda Hardcore differential support brackets deliver improved drivetrain stability, consistent launches, and enhanced reliability when traction and power are pushed to the limit

Dinan Carbon Fiber Strut Tower Braces

Dinan carbon fiber G8x strut tower braces provide additional rigidity and sharper handling to the chassis by reducing flex under hard cornering conditions. With more control, spirited driving becomes easier and infinitely more enjoyable. The lightweight braces are designed with maximum function in mind—and include linking structural elements that completely change the OEM 2-piece strut bar set into one blended system that offers additional strengthening against flex. Not one to take a back seat to functionality, aesthetics are also elevated beyond simple steel bars into striking carbon fiber (matte or gloss) with accents that tie in effortlessly into the highly geometric and angular factory engine bay for an OEM+ feel. The imposing carbon fiber braces can be installed in a matter of minutes and used in conjunction with either the stock or Dinan intake systems. While the braces were designed to specifically tie into the latter for a harmoniously balanced and unified appearance, they can also stand on their own and elicit nearly as equally an impressive visual. Product details:: * Improved chassis rigidity * Decreased flex during cornering * Lightweight: 5.6 lbs. lighter than stock (Dinan carbon fiber: 2.8 lbs. vs. OEM steel: 8.4 lbs.) * 2x2 twill carbon fiber with inset aluminum mounting points for increased strength and improved visual appeal * Designed to mesh seamlessly with the Dinan cold air intake, creating an aesthetically unified engine bay * Bolt-on installation using factory mounting hardware
