James Barone Racing Rear Sway Bar Install

The install of the James Barone Racing rear sway bar for the Gen2 Mazdaspeed3 is straightforward and shouldn’t take more than 20-30 minutes.

Before you begin the install make sure the vehicle is securely supported!

1. Remove the two 17mm nuts connecting the control links to the stock rear sway bar (44-60n*m, 57-75lb*ft). There is one nut on each side of the vehicle. If the threading on the control link turns with the nut you will need a 5mm Allen Key to secure it while you loosen the nut.

2. Remove the four 14mm bolts from the two brackets holding the stock sway bar to the chassis (68n*m, 50lb*ft).

4. Use the supplied grease and apply it liberally to the inside of the supplied bushings. Assemble the new sway bar with the supplied bushings and brackets.

5. Begin to install the new rear sway bar putting the control links in the desired hole on the sway bar. The hole closest to the front of the vehicle is the stiffest setting. The hole closest to the rear of the vehicle is the softest.

6. Put a drop of loctite on each of the four 14mm bolts and install them into the brackets holding the sway bar to the chassis. LEAVE THEM LOOSE FOR NOW! YOU WILL COME BACK AND TIGHTEN THEM LATER!

7. Center the sway bar in the brackets by sliding in left or right and ensure the gap between the control arms and the outside edge of the bushings is equal on both sides. (Picture after instruction #10)

8. Now go back and tighten the four bolts connecting the sway bar to the chassis that you had previously left loose (68n*m, 50lb*ft). (Picture after instruction #10)

9. Apply three drops of loctite to each of the control links, apply one lock washer on each control link, then put the 17mm nut back on each control link (44-60n*m, 57-75lb*ft). Again, you may need a 5mm Allen Key to properly torque these.

10. Install both supplied locating collars on the new sway bar, on the inside of each bushing. Slide each collar closer to the bushing until there is about the thickness of a piece of paper between the collar and the bushing. Once they are both in the correct place us a 3/16 Allen Key to tighten them evenly.

James Barone Racing Rear Adjustable Camber Arms Install

These adjustable camber arms are necessary to bring rear camber back into spec after lowering because lowering significantly increases negative camber, causing excessive tire wear. They also allow up to 3 degrees of negative camber for auto-x and road racing. These adjustable camber arms fit both the Gen1 and Gen2 model Mazdaspeed3s.

This install is straight-forward, but can be difficult without the right equipment.

IMPORTANT: THE CAMBER ARMS ARE NOT IDENTICAL. THE ADJUSTING END FOR EACH ARM SHOULD BE LOCATED AT THE WHEEL OF THE VEHICLE, AND THE JBR LOGO SHOULD BE READABLE FROM THE REAR OF THE CAR.

NUMBERS IN PARENTHESIS FOUND IN THE FOLLOWING INSTRUCTIONS ARE TORQUE NUMBERS TO BE USED WHEN RE-INSTALLING. THE FIRST RANGE OF NUMBERS ARE MEASURED IN NEWTON METERS. THE SECOND RANGE OF NUMBERS IS MEASURED IN POUND FEET.

1. Remove the 17mm bolt connecting the stock rear upper arm to the wheel and brake assembly (76-102n*m, 57-75lb*ft).

2. Remove the 17mm bolt connecting the stock rear upper arm to the frame (76-102n*m, 57-75lb*ft). Removing the bolt can be difficult. A long 17mm open or box ended wrench will be helpful. There is not enough room to fit a ratchet. Once the bolt is out you can remove the arm from the vehicle.

3. Lay the stock arm on the ground and lay the corresponding adjustable arm on top of it. To make sure they are lined up correctly use the two bolts you removed from the vehicle and thread them through both arms. Once the adjustable arm is lined up with the stock arm tighten the jamb nut to lock it in place.

4. Installation is the reverse of removal. If you have trouble installing the new arm due to tight clearances I suggest using moly grease and a soft mallet to slide the arm into place.
