You asked and Steeda listened! The team here at Steeda went hard to work when we started fielding calls of the rear subframe being misaligned from the factory and there being no solution with the BMR CB005 / SR Performance IRS Tie Down kits. So here you have it, Steeda’s new S550 IRS subframe alignment kit for the BMR CB005 / SR Performance IRS Tie Down kits!
The S550’s subframe mounting holes are very large compared to the subframe mounting bolts. Since there is a large difference in bolt and hole size, the subframe can be mis-aligned from the factory up to 1/2″ left to right. The Steeda S550 Mustang IRS Subframe Alignment Kit is made from CNC-machined Delrin to avoid putting two dissimilar metals next to each other like the competition, preventing corrosion. Delrin is also less weight then aluminum or steel inserts and therefore keeping performance in mind. The Delrin sleeves slide into the subframe mounting holes, and fill the extra space left between the subframe mount and bolt from the factory.
Our Steeda S550 Mustang IRS Subframe Alignment Kit guarantees that the subframe will be bolted to the same location every time it is lowered. Eliminating the need for unnecessary alignments.

Note: Note: An alignment is needed upon initial installation, due to the fact it could have been mis-aligned from the factory and with it now being squared in the chassis, some adjustments might need to be made. This part is designed to fit with BMR CB005 & SR Performance IRS Tie Down Kits.
