Almost daily here at Lethal Performance we are asked what the best & most important components are to upgrade in the rear suspension for the 2015+ S550 Mustangs. What good is horsepower if you can't put it to the ground?

Jared 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.

Based on his experience, we asked him to pick out what he felt were the most beneficial components for these cars, the “Bread & Butter” 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!)

In 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.

Sounds intriguing right?

Check out that video here:

I was looking at the BMR BnB I and BnB II kits actually. Can you clarify why one would get one kit over the other? In my comparison, I found that both kits have 6 items each but some differences...

-both have the same cradle bushing lock out
-both have the same double adjustable rear toe rods
-both have the same vertical links
-both have spherical lower control arm bearings but different part #s

-BnB I has differential bushing lock out, BnB II does not
-BnB I has extreme differential bolt upgrade kit, BnB II does not

-BnB II has IRS bracing system, BnB I does not
-BnB II has knuckle toe link bearing, BnB I does not

So some questions I have...
1) Which one is most like Steeda's "Stop the Hop" kit?
2) Will both BMR kits help our cars handle better on the road course/track? Not looking for drag strip performance. [I've got a GT350R]
3) Does BMR have an equivalent to Steeda's 2-Point G-Trac brace?

Thanks
