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 2015 Mustang Steeda IRS Subframe Alignment Kit is made from
CNC-machined Delrin to avoid putting two dissimilar metals next to each
other, 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 2015 Mustang Steeda 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: 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. Product
