Land Rover Range Rover Sport Big Brake Kit Upgrade / TTSPORT Classic 8610

The new Range Rover Sport doesn't lack power — the 5.0-liter LR-V8 makes 375 hp and 510 Nm, and the supercharged version pushes 510 hp and 625 Nm. What it does lack, like most mid-size and full-size SUVs in this class, is a stock brake system built to match that output against a curb weight north of 2.5 tons. Owners of these vehicles routinely report soft pedal feel and fade under repeated hard stops. This car's owner addressed it with a TTSPORT front six-piston / rear four-piston kit, plus a dedicated rear parking brake caliper.

The Problem: A Heavy SUV Outrunning Its Stock Brakes

Big, powerful SUVs like the Range Rover Sport carry a lot of momentum, and stock brake hardware sized for everyday driving can run out of margin quickly once you add spirited driving, towing, or repeated mountain descents into the mix. That's the core issue with heavy platforms generally — it isn't that the factory calipers are poorly made, it's that piston count, pad area, and rotor mass are all sized for a lighter braking task than what a 2.5-ton-plus SUV with 500+ hp actually demands.

To close that gap, the owner went with a matched front-and-rear TTSPORT kit rather than upgrading only the front axle, which keeps braking bias balanced instead of overloading the rear brakes relative to the new front bite.

Vehicle & Kit Specs

Why It Works

• Front six-piston forged caliper: more even clamping across a wider pad gives a more linear pedal and stronger, more consistent bite than the stock caliper.
• Larger 410x36mm front rotor and 380x28mm rear rotor add mass and surface area, which means more heat capacity to resist fade on repeated hard stops.
• Matched rear four-piston caliper with its own dedicated parking brake caliper keeps front/rear brake balance correct instead of overworking the rear.
• The full kit fits behind the car's stock 21-inch wheels, so there's no need for spacers or a wheel change.
