All Probite performance brake discs are sold as pairs for total performance across the axle, they are made to exact standards to match or outperform the corresponding OEM parts for your vehicle.

Compatibility: BMW M340i/M440i G20/G21/G22/G23 2018-
Disc Size: 345mm
Depending on your vehicle compatibility, Probite discs are either solid cast-iron or internally vaned to give structural ventilation through a network of directional or geometric channels that enhance the cooling properties without reducing the structural integrity of the disc.
Probite offers a higher friction coefficient than standard brake discs, giving better braking with every pedal movement, whilst still complying to ECE Regulation 90.
Benefit from visually enhancing designs that are built to give direct replacement fitment for easy installation – no additional bolts, no servo adjustments and no adaptor kits.
Probite products undergo rigorous quality control and testing procedures to ensure unbeatable anti-crack and anti-warp characteristics with every disc.
All Probite discs include 'ProCoat' - the black-phosphate coating that protects against corrosion and grime whilst also helping alloy wheels and calipers to stand out more.
ProGroove
The ProGroove range covers increasing concentrations of perfectly geometric grooves and slots that act like an intense braking fan, whisking away high temperatures and offering excellent pad-refreshing properties for aggressive compound pads.
ProCombo
The ProCombo discs bring the best of both worlds together in an eye-catching and car-stopping combination. Swirling designs of dimpled surface-machinings are alternately matched with grooves or slots to combine improved gas and thermal reductions with a fresh friction surface to the pad that bites harder with every pedal press.
ProHook
The range of ProHook brake discs offer various levels of hook intensity to lift and sweep away gas, debris and moisture with every disc rotation. The advanced machining of the hook allows every driver to find their perfect match depending on their driving style.
*Please Note: Not all designs of each disc are kept in stock and some can carry a lead time of 7-10 working days. Please contact us before ordering if you need your brake discs urgently. We will contact you within 1 working day of ordering with a lead time if there are any delays.*
