If you're looking to upgrade your braking system without sacrificing wheel size, the Baer SS4+ rear brake kit is a solid choice. This setup features a robust S4 4-piston caliper paired with a 13-inch, 2-piece rotor that's both slotted and drilled, giving you that extra bite when you need it. Plus, the zinc plating adds a layer of protection against the elements, so you won't have to worry about rust creeping in.

One of the things I really appreciate about this kit is the attention to detail. It comes with stainless steel brake hoses, which are a must for durability. The calipers are designed with D.O.T. compliant dust and weather seals, so they’re built to handle whatever Mother Nature throws at you. And let’s not forget about the quality bearings and NAS high-grade stainless hardware that come pre-assembled with the rotor. This isn’t just a slap-it-together kit; it’s well thought out.

This SS4+ is specifically designed for those 17-inch wheels, so if you're rocking a set of those, you’re in luck. It’s a great option for anyone who wants to keep that stock look while still having the ability to upgrade to larger wheels down the line. Just keep in mind that park brake cables aren’t included, so you’ll need to source those separately.
