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.

Poor footbed but otherwise good.
Size: 10, Color: British Tan/Dark Chocolate/Natural
Comfortable. Replaced mediocre footbed that has no arch support with something else and it is now great. True to size.

Look and feel awesome!
Size: 11.5, Color: Optic White/Opti
These are awesome shoes - look great really, really white and clean! Love how comfortable they are - and soooo light. I was a little worried they'd get dirty easily, but I've been able to keep them clean. Fit as expected. If you're looking for a great, comfortable, and affordable shoe, check these out!

Great shoe, comfort
Size: 11.5, Color: British Tan/Ivry
Love these shoes, they're super comfy. Laces stayed tied all day. I wear them in a business casual environment, or if I'm going out for a nice meal with my wife. They look good, the color is unassuming and neutral. they also elevate my height, I feel like it gives me an inch or so more versus regular shoes. This is my second pair!
