Anti Squat Adjustment Brackets:

• Mount the bracket to the subframe using small M14 bolts to achieve minimum anti-squat. Tightening torque: 110±5 ft-lbs.
• Mount the bracket to the subframe using longer M14 bolts to achieve maximum anti-squat. Tightening torque: 110±5 ft-lbs.
• Moving the Lower Control Arm upwards will increase anti-squat.

Installing the Toe Arm

The FDF Toe arm sub-assembly for Corvette C6 is common for both left-hand and right-hand sides.

Installing the Knuckle

FDF Billet Knuckles for Corvette C6 are specific to the left-hand and right-hand sides. The image shows the left-hand side component.

• Verify all bolts are torqued properly.
• Flip the shim to change camber.
• Tightening torque for knuckle mounting points: 105±5 ft-lbs.

Installing the Dual Caliper Bracket

FDF Rear Dual Caliper brackets for Corvette C6 are specific to the left-hand and right-hand sides. The image shows the left-hand side component. A single caliper bracket option is also available for using the OEM foot brake and an aftermarket hand-brake.

Step 4: Reassembly

• Double-check all connections and fastenings for security.
• Ensure every bolt and nut is properly tightened.
• Reinstall the wheels and brakes.
• Lower the car back to the ground.

Step 5: Alignment and Adjustment

Recommended Alignment Specifications:

• Camber: 0° to -1°
• Toe & wheel size: Based on individual preference.

These are recommended specifications; adjustments can be made based on individual preference.

• Do not exceed Heim joint adjustments. Each Heim joint should have a minimum of 1 to 1.5 times its diameter in thread engagement within the arm (e.g., a 3/4" Heim joint requires approximately 3/4" to 1 1/8" thread engagement, which is 12-18 threads).
• After installation, obtain a professional alignment from a shop specializing in drifting setups to optimize angles for drifting and ensure the best handling and response.
• Adjust grip kit components as needed to fine-tune steering and suspension for your preferred drifting style, prioritizing safety and performance.

Toe Adjustment: Move the washers up to adjust toe gain based on preference. Tightening torque: 90±5 ft-lbs.

Step 6: Test Drive

• Before extensive use, conduct a test drive in a safe area to evaluate the car's response to the grip kit installation. Note any issues, unusual noises, or handling quirks that may require further adjustments.
• Document any issues and necessary adjustments during the test drive. Address these before engaging in aggressive drifting.
