Yes this 4 piston GT M front kit is engineered specifically for the 19841987 FERRARI TESTAROSSA rear axle at OEM ride height. If your car is lowered more than 25mm or has non standard wheels under 19, contact us first. What's the difference between GT M, GT S, GT R? All three use the same physical caliper body; they differ in internal piston size, pad compound, and rotor pattern. GT M is the street oriented base tier, while GT S and GT R add progressively more aggressive track capability. Are brake pads included? Yes one set of Brembo street performance brake pads is included. Optional upgrades to Pagid, Ferodo, or Schaffen compounds are available. What brake fluid does Brembo recommend? DOT 4 meeting Brembo's specification (minimum dry boiling point 260C). We recommend Motul RBF600 for street and RBF660 for track use. Do I need wheel spacers? No all Brembo GT M kits are designed to fit within OEM wheel offset and caliper clearance specifications for this fitment. A minimum 19 wheel is required.
