Tired of eating front wheel bearings on your S550??

Steeda has a kit that moves you into the PP2 / GT350 style HD 4 bolt front hubs.

Adding these to the wish list!

Looking at these killer 2-piece rotors but man are they spendy!

Steeda Mustang GT Performance Pack 380x34mm Front & 330x25mm Rear Two-Piece Rotor Set (2015-2023)

The 380 x 34mm front 15 rotors (555 6032) weigh 15.4 pounds per pair less than OE solid 1-piece front discs, while the 330 x 25mm rears (555 6033) are 4 pounds per pair less than OE.

Not sure about the durability of a slotted design for track use though.

I've also looked at them a few times but not a chance they fit my snack bracket. Will be ordering new track pads and smooth plain rotors for front of the PP2 before track season comes.
The above kit basically turns front spindle n hub into PP2 spec.

That Steeda kit is a good deal compared to using OEM Ford parts purchased in Canada ... a quick tally of the two hubs and knuckles comes to around $2K CAN with the club discount, pre tax.
