Steeda IRS Subframe Bracket Kits

Steeda's IRS subframe bracket kits provide an immediate improvement in handling and eliminate the flexing of the IRS subframe mounting bracket. The rear suspension subframe of the 1999-2004 Cobra attaches to the car via a cantilevered bracket. The outer half of this bracket is completely unsupported and flexes significantly, leading to less predictable handling as the entire rear suspension system shifts under the car. Steeda's support kits reinforce the bracket and eliminate flexing. Overall handling and responsiveness are improved and wheel hop is reduced.
