If you're looking to amp up your classic ride's braking system without losing that vintage vibe, the SS4+ is where it's at. This setup features a robust S4 4-piston caliper paired with an 11-inch two-piece rotor that’s not just slotted and drilled but also zinc plated for durability. You won’t find any flimsy parts here; we’re talking stainless steel brake hoses and calipers that come with D.O.T. compliant dust and weather seals. Plus, the bearings are top-notch, and the NAS high-grade stainless hardware means everything stays secure and reliable.

What’s great about the SS4+ is it packs all the muscle of Baer's bigger systems but fits snugly under 15-inch wheels. So, if you’re rocking a classic Chevy and want to step up your brake game, this is the perfect choice.

Fitment:

• Works with 1958-1968 GM Fullsize Stock Drum Spindles
• Also compatible with 1963-1965 GM Y-Body Stock Drum and Disc Spindles
