What Is the R1 Concepts eLine Brake Kit?
The eLine series is R1 Concepts' range of complete brake kits. Each kit pairs rotors with pads made for the same vehicle, so you do not have to match parts from different brands yourself (Walmart, 2026).
Kits are sold by vehicle and axle. A front kit, for example, includes 2 rotors and 4 pads, and many kits also include a hardware kit (Walmart, 2026).
R1 Concepts is a US brake parts brand that sells rotors, pads and full kits for cars, trucks and SUVs.
What Comes in an eLine Kit
| Kit type | Rotors | Pads | Hardware |

| Front or rear kit | 2 | 4 | Included on many kits |
| Front and rear kit | 4 | 8 | Included on many kits |

eLine Rotors: What Makes Them Different
R1 Concepts says eLine rotors are made to meet OEM specifications for durability and stability, using G3000/G11H18 cast iron (Walmart, 2026). G3000 is a common grade of automotive cast iron used by many original equipment rotors.
The rotors have a non-directional finish. This is a surface pattern of fine cross-hatch marks instead of circular lines, which helps new pads bed in faster and more evenly, leading to quieter and smoother stops (Walmart, 2026).
A good comparison is sanding wood in several directions before painting. The paint grips evenly instead of following one grain.
eLine Pad Options
eLine kits come with different pad compounds depending on the kit. Listings show two common options:
- Optimum OEp pads: an OE-style formula that is asbestos-free, low dust and fade resistant, with shims for quiet braking (Walmart, 2026). This is the daily-driver choice.
- Performance Off-Road pads: offered on kits for trucks and SUVs used off road (Walmart, 2026).
Check the pad name in the listing title before you buy, so you get the compound that suits how you drive.

How to Install an R1 Concepts eLine Kit
To install an eLine kit, confirm the part number fits your vehicle, clean the hub, fit the rotors and pads with the hardware, torque everything and bed in the new parts. Follow these steps.
- Match the kit's part number to your vehicle's year, model, trim and axle.
- Lift the car safely and support it on jack stands.
- Remove the caliper and bracket, and hang the caliper so it does not pull on the brake hose.
- Remove the old rotor and clean rust from the hub face with a wire brush.
- Clean the protective oil off the new rotors with brake cleaner.
- Fit the rotor, then the bracket, new hardware and pads. Lubricate contact points as shown in our brake grease guide.
- Torque all bolts and wheel nuts to specification, pump the pedal until firm, and bed in the brakes using our bed-in guide.
