Installing LCA bushings on the 8th gen Si

Changing the LCA bushings is a good way to improve your car's launch. It will help with keeping your wheels straight and reduce (or eliminate - depends on the bushings you use) wheel hop. Engine mounts will not eliminate wheel hop.

Is a fairly inexpensive mod and if you do the installation yourself, you get to save a little bit of money as well.

What do you need!?

You do not need a lot...

That's about it!
The most difficult part will be to press out the old bushings and press in the new ones.
You can always leave this part for someone else to do. Is usually one hour job at your local mechanic shop (as long as they have the press).

As a side note, torque traction bars will do the same thing but on the 8th gen Si, the sub-frame design doesn't allow this set-up.

What next!?

Lift up the front of the car on jack stands and remove the front wheels.
You will have to remove both control arms from the car and to do so, you need to remove a couple of bolts and nuts.
There is a total of 6 bolts and nuts that needs to be removed:

The control arm slides out with a little bit of tiny effort. Just be patient and do not force it out.

If you are unlucky like me, the nut from the end-links might give you some trouble. The driver side was stuck and nothing seemed to remove it. We've end up cutting it and replacing it with a new one.
Btw, since I am speaking of end-links ... a good brand to replace our end links is Moog. They seem beefier than stock ones and allows you to install "nipples" (you dirty minds ... :) ... or is it just me!? :| ) to replace/fill up the end-links bushings with grease. Pretty neat!

And then!?

Well, this is a good time to inspect the control arms and make sure all the other bushings that you are not planning to replace are in good condition. Hell, you can even paint the arm if you wish - you know, to make it "Look cooler bro!" :).
After that, get the control arms to a press and have them replace the old bushings with the new ones.
Once this is done, install everything back on (in reverse order). Make sure you tighten all the bolts properly (check and double check) then go out and do some test runs.

As an advise, put in all the bolts and nuts but do not tighten until all are in and you make sure the arm is properly installed. Once everything checks out OK, tighten everything.
Also, put some grease on the new bushings - be generous with it too.

Put back the wheels and head out for a test drive.
The steering should be a little "sharper" and car should be a little bit more responsive when launching it. Also, depending on the bushings you are using, the wheel hop should not be present anymore
Don't confuse wheel hop with wheel spin :). Wheel spin can only be cured with better, stickier tires.

I will do my best to get to all of you!


I am NOT a professional mechanic. Everything I do I gathered from my experience and from other car enthusiasts.
