Fast-road pads give more bite and less fade than standard pads while still working well from cold. Track pads cope with much higher temperatures but can be noisy, dusty and need heat to work at their best, so they suit cars that see regular track use.

If your discs are worn close to their minimum thickness, scored or lipped, replace them with new pads. Fitting new pads to worn discs reduces performance and shortens pad life. Pad and disc kits make it easy to do both at once.

Yes. New pads and discs should be bedded in following the manufacturer's procedure – usually a series of firm stops from speed without coming to a complete halt – to lay down an even layer of pad material and get full performance.

Most manufacturers recommend changing brake fluid every two years. If you do track days, a high-temperature fluid and more frequent changes help prevent a soft pedal under heavy use.

Big brake kits need a minimum wheel size and enough caliper clearance. Check the minimum wheel size on the product page against your M340i (G20/G21)'s wheels, or ask our team to check before you order.
