TEIN is the exclusive distributor for Australian made SuperPro brand of polyurethane bushings. We recently got some SuperPro roll center adjusters in stock. One of the guys here with a new EVO X decided he wanted a set so I took pictures of his install. Since the front lower control arms needed to come off this was the best time to also upgrade the front arm bushing as well.

Here is a picture of all the new parts.

SuperPro RCA for EVO 8/9/10, Part # SPF-FPR-004

SuperPro Polyurethane Bushing for front lower control arm – front inner, Part # SPF2418K

Remove ball joint to hub bolt, disconnect swaybar link and two bolts securing the inner points of the lower control arm.

Pop the dust boot off and remove the C-Clip. An extra set of hands makes things easier.

Easiest and safest to use a hydraulic press to remove the OEM ball joint. Other option is a rent or buy a ball joint tool kit. Note that on the underside of the arm a small ring of aluminum may break off or stretch when the ball joint is pressed out – this is normal.

OEM ball joint removed. Cleanup any heavy scratches to the arm (there should not be any if the press was used properly).

Here you can see the OEM ball joint next to the new SuperPro unit. The SuperPro unit has a taller base instead of a taller shaft like other manufacturers. This makes it more rigid.

Press in the new RCA. Make sure the RCA sits all the way in which will make the groove for the C-Clip flush with the top of the arm.

Install the C-Clip.

Pressing out the front inner bushing. Takes a little creative positioning to get everything to line up perfectly.

Cleanup the arm from any scratches and install the new SuperPro bushings. Use plenty of grease and insert the two bushings first. Then grease the pin and use a vice or press to push it in.

Arm installed. You can clearly see the height difference. Make sure to torque all bolts to factory settings.

This bolt should be tightened and torqued while the car is at 1G so that the bushing’s natural position is at ride height and not full suspension droop.

You will notice that the SuperPro kit does not include new taller tie rod ends. According to SuperPro engineers new tie rod ends are not needed but due to high consumer demand SuperPro will be including new tie rod ends in the near future.

Lastly have an alignment done as both camber and toe will have changed.
