Overview
The Baer Brakes 4302483FR is the dual SS4 Plus Deep Stage rear brake kit in Fire Red, made for GM 10/12 bolt C-clip rear ends whose housing ends are fitted with C-clip eliminators. Four S4 calipers clamp 11 inch vented two-piece rotors that are slotted, drilled and zinc plated.
The SS4 Plus Dual Deep Stage is built as a drag race system for heavy, fast cars that may also see street use. Each of the four calipers uses 1.375 inch pistons in hard anodized aluminum with stainless steel abutments. High friction pads designed for drag race applications come with the kit.
Key features
- Four S4 calipers in Fire Red, each with four pistons
- 1.375 inch pistons, hard anodized aluminum with stainless steel abutments
- 11.0 inch vented two-piece rotors, slotted, drilled and zinc plated
- Billet aluminum hats drilled for 5/8 inch wheel studs
- High friction pads for drag race use, FMSI DR1
- Fits most 15 inch and larger wheels, manufactured in Phoenix, Az
Plumbing four calipers
Four calipers add more connections than a single-caliper rear, so line routing and fittings deserve extra time. Each caliper needs a clean, straight path that clears the axle, control arms and suspension travel. Bend lines by hand where needed and keep them away from exhaust heat and moving parts.
Bleeding a multi-caliper system takes patience. Work in a consistent order, usually starting farthest from the master cylinder, and keep the reservoir full so air is not drawn back in. Pedal feel should be firm before the car moves. Fluid that has absorbed moisture from age should be replaced, since it boils at lower temperatures under heavy braking.
- Use brake-rated lines or fresh flexible hoses
- Check each fitting for seepage after bleeding
- Compare wear across all four pads

Vehicle fitment
The kit fits GM 10/12 bolt C-clip small car pattern rear ends whose housing ends have C-clip eliminators. Match your year, model and trim to the fit before buying.
Rear ends with other axle flange patterns fall outside this kit’s fit, so compare your vehicle’s axle type first.
Installation notes
The rotors are pre-assembled with NAS high grade stainless hardware, and mounting hardware comes with the kit. Four calipers mean more brake line connections than a single-caliper setup, and hoses are not included. Because the calipers clamp a heavy car’s full braking load, have the finished installation inspected before first use.
What’s included
Four S4 calipers with 1.375 inch pistons, pre-assembled 11.0 inch rotors with stainless hardware, mounting hardware and high friction drag race pads.
Not included: brake hoses and a park brake.
