If you're looking to upgrade your braking game, this front brake system from Baer is a serious contender. It’s got the 6S 6-piston Monoblock caliper paired with a hefty 14-inch 2-piece rotor that’s been slotted and drilled, plus it’s zinc plated for that extra layer of protection against the elements. You’ll appreciate the stainless steel brake hoses included in the kit, along with calipers that come with D.O.T.-compliant dust and weather seals. The bearings are top-notch, and the NAS high-grade stainless hardware means you won't have to worry about rust or wear.

This setup is designed specifically for 2003-2007 Cadillac CTS spindles, so you know it’s going to fit like a glove. And let’s talk about the 6S and 6R R-Spec calipers—they’re Baer’s flagship models, crafted from a single piece of US-sourced 2618 forged aluminum. That’s some serious quality right there.

Why go for the Extreme+?

• It’s got that US-made forged MonoBlock caliper that really stands out.
