About the racing brake pads , we have a variety of formulations suitable for different application environments.
1) Street , we have low dust, and then no abnormal noise, we call SD formula
And this is similar to DS2500, which we call the SN formula
We also have a more expensive, for luxury cars, more comfortable feeling of large friction, the initial section will not be very hard, will not nod, but the friction in the middle and back section will be very large, very linear, we call SF formula
2) Track day, we have a lot of friction, but a lot of dust, we call ST formula
Less dust, high temperature resistance is also OK, but the performance is average, we call DR Formula
3) Racing Track , high friction sprint race formula, we call ZZ formula
Low friction endurance formula, we call SR formula
There is also a pure rear-wheel formula, which we call the RT formula
ZZ SR is Track Racing
DR ST is high performance Street
SF SN is high friction Street
SD is low powder and no noise Street
