Steeda noticed a lot of Mustang owners had rear subframes misaligned from the factory, by up to 17mm either way. Steeda went to work and created our must-have S550 IRS sub-frame alignment kit! After all, who wouldn't want their rear subframe locked centrally where it belongs? Homologated / Certified for European use

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 Sub-frame 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 aluminium or steel inserts and therefore keeping performance in mind. The Delrin sleeves slide into the sub-frame mounting holes, and fill the extra space left between the subframe mount and bolt from the factory.

Our Steeda S550 / S650 Mustang IRS Sub-frame Alignment Kit guarantees that the sub-frame will be bolted to the same location every time it is lowered. Eliminating the need for unnecessary alignments.

Note: An alignment is needed upon installation due to the fact it could have been misaligned from the factory and with it now being squared in the chassis, some adjustments might need to be made.

Great Wall Shelves – Sturdy, Easy to Install, and a Fantastic Value!
Size: 4 pcs: 15.7*5.7, Color: White
I’m really happy with these wall shelves! They’re sturdy, well-built, and hold up perfectly under weight—no concerns about them sagging or bending. The installation was super simple, and everything was clearly labeled with no missing parts, which made the whole process smooth and stress-free. I love that they come in a set of four, making them perfect for displaying books, plants, or decorative items in multiple spots around the room. The design is sleek and minimal, so they fit in with pretty much any style of decor. Overall, these shelves are a great value, and I would definitely purchase them again. Highly recommend if you’re looking for reliable and easy-to-install shelving!

Just Ok.

They look nice but they aren’t sturdy and do not hold much weight. I’ve bought better ones on Amazon.
