What good is horsepower if you can't put it to the ground?\u003cbr\u003e\n\u003cbr\u003e\nJared took a trip over to BMR Suspension in Seffner, FL with our 2018 Mustang GT (aka Project Goldmember) to get the “Kelly Aiken” treatment. While there, we were able to pick Kelly's brain on the IRS and it's components. He has a surplus on knowledge on these cars from not only his own car (even planting GoPros underneath to monitor the suspension's activity) but also from the vast amount of fast cars using BMR Suspension, including 2 of the fastest IRS cars in the country.\u003cbr\u003e\n\u003cbr\u003e\nBased on his experience, we asked him to pick out what he felt were the most beneficial components for these cars, the \u003cstrong\u003e“Bread \u0026amp; Butter”\u003c\/strong\u003e as he calls it in the video. The following components will support cars going well into the 8s and those wanting to see low 1.2-1.4 60's (If you're faster than that, they have components for that, too!)\u003cbr\u003e\n\u003cbr\u003e\nIn an IRS car there are a couple of issues to address. The first issue is that the entire cradle assembly will move\/rock. In our 2018 A10 car, Kelly was able to point out just how much movement there is in a factory setup. The factory cradle bushing has a small lip on the top which is a limiter. On our car, when we launched it at the track, this limiter was hitting the chassis, leaving a witness mark on the body from the cradle moving\u003cbr\u003e\n\u003cbr\u003e\n\u003cstrong\u003eCB005 – Cradle Bushing Lockout Kit\u003c\/strong\u003e\u003cbr\u003e\nDesigned to eliminate cradle bushing deflection \u0026amp; wheelhop\u003cbr\u003e\n80%-90% reduction in fore\/aft and lateral cradle bushing deflection\u003cbr\u003e\nComes with spacer rings to lock out the top of the cradle bushing so that it doesn't deflect at WOT\u003cbr\u003e\nComes with lower bushing mounts to eliminate lower bushing movement, keeping it from dipping down \u0026amp; causing the pinion to rise\u003cbr\u003e\n\u003cbr\u003e\n\u003cstrong\u003eBK081 – Spherical Lower Control Arm Bearing\u003c\/strong\u003e\u003cbr\u003e\nDesigned to eliminate cradle deflection \u0026amp; wheelhop\u003cbr\u003e\n“One of the most important \u0026amp; overlooked components” -Kelly Aiken\u003cbr\u003e\nFactory bushings are molded from soft rubber \u0026amp; contain voids\/air pockets, causing movement of the lower control arm during aggressive launching\/driving. The solid spherical setup eliminates these voids, therefore eliminating the control arm movement.\u003cbr\u003e\nAlso keeps the wheels from moving forward due to bushing deflection at WOT\u003cbr\u003e\n\u003cbr\u003e\n\u003cstrong\u003eBK051 – Differential Bushing Lockout Kit\u003c\/strong\u003e\u003cbr\u003e\nDesigned to eliminate the voids in the stock differential bushing setup\u003cbr\u003e\nLocks the differential movement so that breakage of driveline components is avoided\u003cbr\u003e\n\u003cbr\u003e\nIf you're going to do the differential bushings, we HIGHLY suggest upgrading the hardware while you're in there. Not only are the bolts themselves stronger than the OEM pieces, but the kit also plays an integral role in limiting differential movement. In the rear bushing, the stock bolt has a ton of play in it as it is a smaller diameter than it's location. This causes the diff to be able to move, as shown by the bolt being off center in our car, which in turn changes pinion angle, causing vibration \u0026amp; driveline parts carnage (like us breaking our driver's side axle on Project Goldmember). This play in the bolt also leads to the bushing \u0026amp; cradle actually slicing\/cutting the bolt when the car is loaded up \u0026amp; launched. No bueno! Then there is the front bushing setup, which is a threaded design from factory. Because the bushing sheer strength is relying on the threaded part of the bolt, it is much weaker than if it were to rely on the shank (or solid) part of the bolt. These are all helped with the hardware upgrade kit.\u003cbr\u003e\n\u003cbr\u003e\n\u003cstrong\u003eLP-550179 – Extreme Differential Bushing Hardware Upgrade Kit\u003c\/strong\u003e\u003cbr\u003e\nDesigned as an upgraded version of BMR's RH017 Hardware Upgrade Kit\u003cbr\u003e\nUpgrades both the front \u0026amp; rear differential bushing bolts to stronger pieces\u003cbr\u003e\nSleeve placed in rear diff bushing eliminates void from factory\u003cbr\u003e\nFront bushing threads are drilled out \u0026amp; bolt is replaced, with bushing sheer on solid part of bolt and a nut in the rear, which is roughly 70% stronger\u003cbr\u003e\n\u003cbr\u003e\nContinuing on, the following components will allow more fine tuning of the rear suspension:\u003cbr\u003e\n\u003cbr\u003e\n\u003cstrong\u003eTR005 – Double Adjustable Rear Toe Rods\u003c\/strong\u003e\u003cbr\u003e\nStock stamped steel pieces equipped with eccentric bolt slip \u0026amp; pivot under load, changing the alignment of the rear wheels\u003cbr\u003e\nBMR pieces keep geometry better during suspension arc due to offset spherical bushing\u003cbr\u003e\nCome with lockout plates for the mounting point to eliminate the eccentric bolt from factory that turns\u003cbr\u003e\nAllow for a wide range of adjustment\u003cbr\u003e\n\u003cbr\u003e\n\u003cstrong\u003eTCA048 – Vertical Links\u003c\/strong\u003e\u003cbr\u003e\nLight \u0026amp; strong, while still offering bushing compliance \u0026amp; no increased NVH\u003cbr\u003e\nLimit range of cradle movement\u003cbr\u003e\nOnly vertical link on the market that has ability to grease\/service the bushings ON the car\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: #3399ff;\"\u003e\u003cstrong\u003e\u003cspan style=\"color: #3399ff;\"\u003e\u003ca href=\"https:\/\/www.lethalperformance.com\/info\/tech-tips-bmr-s550-rear-suspension-components\" target=\"_blank\"\u003eFor more info CLICK HERE!\u003c\/a\u003e\u003c\/span\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNote\u003c\/strong\u003e: Vertical links do not fit:\u003cbr\u003e\nMach 1\u003cbr\u003e\nGT350\u003cbr\u003e\nGT500\u003cbr\u003e\n2024 GT \u0026amp; Darkhorse w\/ rear brembo brake upgrade\u003c\/p\u003e","brand":"BMR Suspension","offers":[{"title":"Default Title","offer_id":47954758762754,"sku":"LP-S550BB","price":769.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0787\/0618\/0354\/files\/breadbutter.jpg?v=1785025294","url":"https:\/\/www.lethalperformance.com\/products\/bmr-suspension-2015-2025-mustang-bread-and-butter-package","provider":"Lethal Performance","version":"1.0","type":"link"}
