Overview
The Baer Brakes 4302481S is an Extreme Plus rear brake system from Detroit Speed (DSE). It is a general fit for the GM C6/DSE floater rear. Its silver 6S caliper is a forged one-piece monoblock with six pistons, clamping a 14 inch rotor.
Baer assembles the hubs before they ship, with all bearings and races installed and packed with Redline synthetic grease. The system is ready to bolt onto the control arms once it arrives. Stainless steel pistons are staggered to reduce uneven pad wear, and dual seals guard against dust, weather and pressure.
Key features
- Forged one-piece monoblock 6S caliper with six pistons
- Staggered pistons to minimize uneven pad wear
- Stainless steel pistons, abutments and noise suppression clips
- Dual seals for dust, weather and pressure
- Two-piece slotted, drilled, zinc-plated 14 inch rotor with billet aluminum hat
- Minimum wheel diameter 18.0 inch, manufactured in Phoenix, Az from US sourced materials
Clearance and wheel fit
Bigger calipers and rotors need room. A six-piston caliper and a 14 inch rotor take up space inside the wheel, so check clearance between the caliper, the rotor and the wheel spokes before mounting. Confirm the wheel meets the minimum diameter for the system and that the tire sidewall will not rub the caliper at full steering lock.
Control arm and axle geometry also matter. Hub and bearing assemblies that arrive pre-built still need correct torque on the axle and proper alignment after installation. Floater axles carry the wheel load, so check the hub seal and bearing play after the first drives. Ride height changes can alter caliper clearance, so recheck fit after suspension work.
- Measure caliper clearance to the wheel barrel
- Check brake hose length through full suspension travel
- Torque the wheel and hub fasteners after the first drive

Vehicle fitment
It is a general fit for the GM C6/DSE floater rear. Check your year, model and trim with the fit before buying.
Other rear axle designs are outside this kit’s fit, so check the axle type before buying.
Installation notes
The hubs arrive with bearings, races and Redline synthetic grease already installed, so the work centers on bolting the system to the control arms. Because the minimum wheel diameter is 18.0 inch, confirm wheel clearance over the 6S caliper and 14 inch rotor before mounting. Rear brake components should be installed and checked by a qualified shop.
What’s included
The complete rear brake system described above: a 6S caliper, a 14 inch rotor with billet aluminum hat, and hubs with bearings and races installed.
