Apec Black Brake Disc (DSK3990B)

Apec Brake Discs like this Brake Disc DSK3990B feature the OE quality you expect when changing such a vital component on your vehicle. Innovation is the ultimate means of providing that quality, through methods that are entirely unique to the company. Apec Brake Discs distinguish themselves with lasting product value at the manufacturing level. They are produced using cutting edge technology, and every part is tested to homologation protocols that assess braking performance over a range of temperatures and pressures.

Key criteria such as disc integrity, thermal cracking, and disc thickness variation (DTV) are observed and synchronised for performance with every purchase. Apec Discs have hubs and edges coated for a like-for-like replacement. Unlike OE parts, however, the friction surfaces are masked and uncoated to prevent brake pad contamination, boosting braking efficiency.

All Apec Discs are supported with a 3Y36K warranty guarantee so you can face the unexpected without worry.
