I think they say no, but it would be wiser to have it done anyway considering the price is so small and the cost of tires is so great relative. Lets see what RR racing says.

To be on the safe side get the alignment. Prior to doing the USRS, I would aim for zero toe to save the front tires, but when you install the USRS you tend to gain caster and toe out, so it really depends what alignment you start with prior to USRS installation. Bottom line, if in doubt, check front toe alignment to be on safe side.

We include thorough instruction, but I will post some info later today or tomorrow.

If I understand correctly, this is a simple remove and replace type of task? With an alignment recommended to be done? Is new hardware provided? Thanks in advance...

Everything you need, other than basic tools, is provided. The bushing/housing/shaft/thrust washer come pre-assembled and pre-lubed, you do not need to do anything.

Installation is just like installing the stock bushing, except when you insert the USRS, you first torque it down lightly, then adjust the pre-load bolts on the side of the housing, and then you apply final torque spec on the bolts that attach the USRS to the subframe.

Removal & Installation step by step (no need to remove wheels, car can be on lift, jack stands, or ramps):

(1) Removal of the Original Equipment (OE) bushing. Using a 22mm & 17mm socket, remove the 2 bolts that attach the lower control arm (LCA) bushing housing to the sub-frame. Using a 14mm socket, remove the 4 bolts that attach the 2 sub-frame reinforcement brackets.

(2) Using a 22mm socket, remove the nut located at the end of the LCA spindle.

(3) Once the bushing/housing assembly is loose, it can be removed by using a pry bar to press down on the trailing end of the LCA as shown in the picture below. This will give enough clearance to slide the OE bushing/housing off of the LCA spindle.






(4) Slide the USRS onto the spindle. Install the brace, and loosely tighten all bolts to 10 ft-lbs of torque.

(5) The USRS has two pre-load adjustment bolts. Carefully and loosely tighten bolt pre-load bolts until they come to a stop.

(6) Apply an additional ¼ turn to each preload adjustment bolt.






(7) Check to make sure that you cannot easily insert the 0.020” feeler gauge between the thrust washer and the poly bushing. If the gauge can be inserted, apply an additional small incremental turn to the preload adjustment bolt.

(8) Apply the final torque to the USRS-to-subframe bolts and spindle nut, and you are done!

Thanks for posting this. This will the DIY guys or the techs at the shops/dealerships.

Thank you very much for clarifying the installation process.

Great DIY, thank you. Is it possible to update with torque values?

Please post your opinions when you are done . Eager to get an idea of what a number of people feel. Mine should be shipping out tomorrow.

eddyisf

can't wait to install mine as well put my order in on Friday i hope i get them soon

also put in an order for the air/oil separator but i think there on back order

imp0rted1

just placed an order! hope to receive soon!

thanks for the DIY tips!

RR racing needs to post up a videos of their bushing in action. Im sure it coming soon

Those that have installed this recently:

1: Have you gotten the car aligned with these bushings?

2: How far were your specs out of alignment after the install?

Trying to determine how quickly I need to get it in the shop to get it aligned. Thanks

Which part is thrust washer and poly bushing are you talking about for the gauge feeler? Please clarify and torques spec for those bolts. Thanks!

Excited to get mine this week. Going to to the Air /Oil seperator as well. Curious to see how much oil that thing will catch with all the track days and triple digit speeds I do regularly.

Still looking for more feedback on the feel of the car with the new bushing .
