TDMi 6 Piston Big Brake Kit

TDMimports 6 pistons Big Brake kits are designed for high performance street and track usage. All TDMimports big brake kits are designed to directly bolt on to stock spindles for quality OE like fitment. 



In order to have a reliable brake system, TDMimports calipers are built using a very high standard in material choice. TDMimports utilize 6066 billet alloy and T651 heat treatment process which is 30% stronger than standard 6061 billet alloy and less likely to deform during extremely high temperatures.  On the other hand, our brake caliper pistons material uses 7075 billet alloy with T651 heat treatment. T651 enhances the durability and longevity twice that of a standard heat treatment process.

Kits with with our 330x28 and 355x28 come with our Jumbo caliper to fit the wider sized rotor.


To meet above average standards when producing reliable brake discs, TDMimports selected better quality FC-25 steel mixture with high cast carbon. This process increases our maximum capable temperature to 900 Celsius.  This provides a higher level of stress and temperature to be achieved without excessive material expansion or distortion. In current markets, most rotors are made of a lower grade steel, for instance FC-20 and FC-22 have a heat expansion by as much as 1.2-1.5mm when reaching temperatures of 500 Celsius.  However, TDMimports’ rotors will only expand by around 0.45 cm in comparison. 

2-Piece Rotors

TDMimports replacement ring is made of FC-25 steel mixture with high cast carbon. Single piece rotors are made of the same material. For the Alloy Hat, TDMimports selected 7075-T6, forged and hard anodized in a champagne color.
