XYZ Racing Hollow Rear Brake Kit — Tesla MODEL 3 PERFORMANCE (2017-2020)

The Model 3 Performance carries close to 1,850kg, and on a circuit its rear axle works harder than most EV owners expect: regen tapers as the pack heats and the battery fills, handing repeated heavy stops back to the friction brakes the standard rear setup was never sized to absorb. The XYZ Racing Hollow Rear Big Brake Kit for the Tesla Model 3 Performance (2017-2020) replaces that rear hardware with a larger, vented package built to take the heat.

This is a rear-axle upgrade, a matched pair of left and right corners, for owners running track sessions, fast B-roads or repeated high-speed motorway stops, where the original rear discs glaze and the pedal goes long. The two-piece floating disc trims rotating and unsprung mass while the bigger swept area gives the rear brakes the thermal headroom the car’s weight and instant torque demand.

What this rear brake kit does for your 2017-2020 Tesla Model 3 Performance

After fitting, the first thing you feel is a firmer, more consistent pedal on the second and third hard stop, the point where the standard rear brakes start to give up. The larger vented discs shed heat faster, so rear bite stays predictable through a full track session instead of falling away after a couple of laps. Three pad compounds let you match the car to its use: Street for daily commuting, Sport for spirited road and occasional track work, and Racing for sustained circuit abuse. Because the kit adds rear thermal capacity, brake balance stays steadier under threshold braking, which settles the back axle as you trail into a corner. The two-piece floating disc also cuts rotating mass at each rear corner, a small but genuine gain on a car this heavy.

About the Hollow rear brake kit

XYZ Racing builds this as a bolt-on big brake kit for the rear axle, pairing oversized vented discs with a fixed multi-piston caliper sized for the Model 3 Performance’s mass. The discs use a two-piece floating construction so the friction ring expands against an alloy bell to reduce thermal distortion and rotating weight without surrendering swept area or heat capacity, and the vane design pulls cooling air through the rotor under sustained load. The caliper body is a hollow-cast forging as standard, with an optional Hollow Racing upgrade rated to 1000C and a two-year warranty for circuit use. Caliper finishes run at no extra cost across Red, Yellow, Gold, Black and Anodized Black, with a Custom Color in any Pantone for £150 plus premium polished-forged and candy options, so the hardware visible behind an open wheel can be specified to taste; disc faces are drilled or slotted at the same price, and the centre bell upgrades to a five-colour anodized two-tone or titanium at checkout. The three friction options, Street, Sport and Racing, cover everything from a quiet daily compound to a high-temperature pad that holds together on circuit. It is engineered specifically to address the weak point of a heavy, fast EV: rear thermal capacity under repeated heavy braking, where regen alone cannot carry the load.

Fitment for the Tesla Model 3 Performance (2017-2020)

This kit is the rear-axle fitment for the Tesla Model 3 Performance built between 2017 and 2020. It is position-specific to the rear, so pair it with the matching front kit if you want a balanced upgrade across both axles. Confirm your build year falls inside the 2017-2020 span before ordering, then choose your caliper colour and pad compound when you order.
