Detroit Axle Drilled & Slotted vs Rear Kit — Which Is Better?

Price — Detroit Axle Rear Kit Wins

The rear kit undercuts the drilled & slotted by. A small gap for a 4-wheel set, but meaningful if budget is tight.

That could cover brake fluid or shop labor. In a safety-critical part, spending slightly more may yield confidence, but the rear kit proves value without skimping on ceramic pads.

Budget-focused DIYers doing a rear-axle replacement will find the rear kit an unbeatable dollar-per-brake proposition. If you're upgrading all four corners, the drilled kit's premium buys fade resistance.

Rating — Rear Kit Edges Ahead

4.6 stars against 4.5 stars seems slim, but across 22,452 reviews it signals real-world satisfaction. Buyers report smoother, quieter stops.

The rear kit's higher rating stems from consistent, quiet performance out of the box. Owners praise the ceramic pads for low dust and smooth engagement from the first stop.

If you value a hassle-free install and immediate performance, the rear kit's 4.6-star average — with over 22,000 reviews — makes a compelling case.

Review Count — Drilled Kit Leads on Trust

29,825 reviews provide a deeper validation pool, especially for a safety component. The drilled kit's extensive buyer feedback covers more fitting variables and long-term wear.

A larger review base means more real-world data on rotor warping, pad life, and noise across different climates. Reassuring for drivers in snowbelt regions facing salt and temperature swings.

If you're risk-averse and want the most-proven option, the drilled kit's 29,825 reviews act as a safety net. The rear kit is still strong at 22,452, but the sample size advantage is clear.

Rotor Type — Drilled & Slotted Dominates

Drilled and slotted rotors are engineered for performance. The holes evacuate gases and water; the slots sweep away debris, reducing brake fade by up to 20% during hard stops.

On mountain descents or highway panic stops, the drilled kit maintains bite when standard rotors might overheat. For spirited driving in a G37 or 370Z, that's the edge you feel.

The rear kit's solid rotors work fine for routine commuting, but they won't match the fade resistance or wet-weather response that drilled rotors provide.

Pad Material — Both Use Ceramic (Tie)

Both kits include ceramic pads, which produce 35% less dust than semi-metallic and operate quietly. That's a win for keeping alloy wheels clean and commute cabin silent.

Ceramic also lasts longer in light-to-moderate use, though it may sacrifice a bit of initial cold bite compared to semi-metallic pads.

For daily driving across US suburbs, ceramic is the right call — less noise, less dust, and still plenty of stopping power for any legal speed.

Wheel Coverage — Drilled Kit Goes All Four

A 4-wheel kit replaces rotors and pads on every corner, restoring balanced braking. The rear kit only addresses half the system, leaving the front untouched.

Mismatched wear between new rear and old front brakes can cause pulling and uneven stopping. If your front rotors are worn, you'll need to source a separate front kit, adding cost.

The drilled kit's completeness makes it the one-and-done solution for a full brake overhaul. The rear kit suits specific need: when only the rear is due.

Best For — Different Missions

The drilled & slotted kit targets Infiniti and Nissan sports car owners seeking an upgrade over OEM. The rear kit is designed for Ford and Lincoln full-size car owners needing rear replacement.

If you own a G37 or 370Z and enjoy spirited driving, the drilled kit is the obvious upgrade. For a Taurus or MKS daily driver, the rear kit aligns with normal maintenance.

Fitment is the deciding factor — always verify your vehicle's exact model and year. The two kits have no overlap in compatibility, so choose based on your car, not just preference.
