Eliminate Wheel Hop and Deflection. We know you love how the Independent Rear Suspension of your S550 Mustang can handle the tight curves of a long, twisty back road. We also know you are not at all thrilled with the serious wheel hop issues that the factory IRS suffers from under rapid acceleration. Well SR Performance has come up with the solution with their IRS Tie Down Kit. SR Performance designed their IRS Tie Down Kit to reduce excessive bushing and cradle deflection, the main culprit of wheel hop, to greatly improve traction for quicker more consistent launches at the track and on the street.

Tubular Steel Construction. SR Performance manufactures their IRS Tie Down Kit from MIG welded, heavy duty, square tubular steel for superior strength and rigidity. This kit is then complete in a durable, black powder coated finish for enduring corrosion resistance and aggressive good looks.

No Increase in NVH. The SR Performance IRS Tie Down Kit is engineered to dramatically minimize cradle bushing deflection with little or no increase in NVH (Noise, Vibration and Harshness). Because there is no discernible change in NVH, this SR Performance IRS Tie Down Kit is ideal for street, performance and race applications.

Straight Forward Installation. The SR Performance IRS Tie Down Kit can be installed with just basic hand tools in about two hours. This IRS Tie Down Kit utilizes the existing stock mounting points with no welding, cutting or extra modifications required. Please note that an alignment, by a qualified shop, is suggested after installation.

Application. The SR Performance IRS Tie Down Kit is designed as a direct bolt-on upgrade for use on 2015 to 2018 Fastback Mustangs equipped with the factory Independent Rear Suspension (IRS), including the V6, EcoBoost, GT and Shelby GT350 models. Not intended for use on Convertible models.

Will this fit with the steeda subframe installed? Thanks Jerry

  • This tie down kit would have no problem fitting with the Steeda subframe installed.

Aside from being $20 less expensive, how does this compare to the BMR cradle lockout kit in quality and performance in reducing wheel hop?

Michael

  • This will be a better bang for your buck, however the BMR kit will be the better option between the two.

Will you need rear alignment after this installation?

    Good product

    Easy to install. Helped with wheelhoops, but did not eliminate them. Do not expect that it will core 100 of wheelhoop.

    Noticeable difference/fast install

    Noticeable difference in handling and wheel hop. Install is fast and straight forward. Installed while doing Eibach Sportline springs. Easily one of the first mods you should do before any other mods.

    What..a..pain

    Build quality was less than perfect. The paint was chipped in places on delivery and one of the welds was missing paint completely. Not a huge deal since this part is never seen, but worth mentioning. Pro tip: if one of your front subframe bolts won't line up loosen the other three main bolts and it should be easier to get into position. I had to do this and it was still a pain to get everything buttoned up. This install can take 30 minutes or 10 hours. It all depends how your subframe is lined up from the factory. Haven't had a chance to truly test if the wheel hop is gone but I assume from other reviews it did the job

    SR Performance IRS Tie Down Kit

    Had the steeda sub-frame braces before, but I like these ones better, I like the fact that they hold the frame down at the actual points where it connects to the car, rear feels more solid than before, not that the steeda didn't work, but that these ones do a better job in my opinion

    SR Performance great parts

    I must really praise SR Performances for their quality and price. I've now install their lowering springs and IRS Tiedown kit.....both items fit perfect and made my 2015 mustang ecoboost look and perform as they said it would. Lowering my suspension 1" on all corners made for a much improved stabile ride...corners great,reduced hard braking dives. And the IRS Tiedown kit reduced wheelhop almost completely. Feels great. A must for all 2015 mustang ecoboost.

    SR IRS Tie Down Kit

    I installed the SR IRS tie down kit this past weekend and I am very impressed with the product. The TIG welds look fantastic and the part feels incredibly strong. The car feels MUCH more planted and there is less wheel hop. Off the line, there is less spinning and more power to the ground. HIGHLY recommend this for your S550!
