Lockout your rear IRS subframe on your S550 and S650 Mustang with an IRS Subframe Support Brace System from BMR's suspension! The subframe of your Mustang can deflect under hard acceleration, causing slower and inconsistent launches. BMRs IRS Subframe Support Brace System (CB762) improves the performance of your vehicle and is designed for street performance, drag racing, and handling applications. When performance is a must, rely on BMR's suspension!

Reduce Wheelhop, bushing deflection, and cradle movement on your S550 Mustang with a Level 1 Cradle Bushing Lockout Kit from BMR's suspension. Built from 6061-T6 billet aluminum and stainless steel, BMR's CB010 Cradle Bushing Lockout Kit is designed to reduce cradle bushing deflection, which is one of the biggest causes of wheelhop. BMR's CB010's billet aluminum upper bushing lockout rings capture the inner bushing sleeve (front and rear) and the outer lip of the bushing cup on the cradle (front). The lower bushing locating washers (front) capture the bottom portion of the bushings' inner sleeves. By capturing both parts of the bushings' inner sleeves, movement on any plane (fore/aft, lateral, and vertical) is nearly eliminated. BMR's suspension designed the CB010 Cradle Bushing Lockout Kit for any application. This 100% bolt-on kit use existing boltholes and hardware, allowing for easy installation with simple hand tools. Once installed, the Cradle Bushing Lockout Kit reduces bushing and cradle deflection with nearly no change in NVH. (During BMR's testing, no change in NVH was observed without accompanying modifications.) BMR's suspensions CB010 Cradle Bushing Lockout Kit allows you yo affordably and effectively lessen wheelhop, bushing deflection, and cradle movement. Throughout testing, BMR has seen about an 80%-90% reduction in fore/aft and lateral cradle bushing deflection. A car with no other mods and stock tires that isn't driven overly hard is going to see a 90% or higher reduction, while a more race oriented S550 with sticky tires will see slightly less of a reduction. Launching the test vehicle at over 7,000 rpm on drag radials, BMR'saw about an 80% reduction in bushing deflection. Through the testing BMR has seen a 95% or greater reduction in vertical deflection in all testing situations. When performance is a must, rely on BMR's suspension! Installation time is 1-2 hours. Proudly made in the U.S.A.!
