VTT E9X/E8X Rear Drag Brake Conversion Kit

VTT ultimate E8/9X ultimate rear brake conversion kit

VTT is happy to announce its new rear brake conversion kits for the E8X/E9X platforms. We take what already exists on the market, and make it much more complete, and much more performance-oriented while keeping the clearance for those 15” wheels. This kit replaces your rear brake rotors and calipers to fit 15″ wheels. It includes lightweight VTT calipers to go from the single-piston factory caliper to race-inspired 4-piston calipers. While dropping up to a whopping 20 LBS of unsprung weight off the back of your vehicle!

 The kit consists of:

• 2 Rotors (Plain Or Slotted) Plain are Centric 125 Series, and Slotted are Genuine Stop-Tech rotors
• 2 VTT 4 Piston Calipers
• 1 set of high-performance VTT Brake pads Race
• All hardware required for the swap, including brackets. bolts, and adapter fittings
• Stainless Steel upgraded rear brake lines.

MANY MORE AGGRESSIVE BRAKE PAD COMPOUNDS EXIST FROM VARIOUS MANUFACTURERS, AND YOU CAN TAILOR TO YOUR NEEDS.

6-PISTON DYNAPRO PAD STYLE 6712

4-PISTON DYNAPRO PAD STYLE 7812

These kits will bolt directly onto the chassis specified, BUT many different 15” wheels in many different offsets exist, we cannot guarantee this will clear your wheel/tire combo without some clearance. We can 100% say they clear Weld RTS 15×10 as this is what we tested on.

Please note modifications MUST be made to the vehicle to fit this kit. You must remove the rear brake dust shield
