Thread: WHiteline KCA303M

Hey fellas I just picked up a set of the whiteline caster bushings. These are the motorsport version.

I bought them online from upscale automotive. They got me the bushings for 86.81 shipped. I'm not sure if there is a place to get these for a cheaper price, but I just thought I'd share this with others. I ordered them on sunday and they got to me today. They ship out from somewhere in PA not South Carolina where Upscale is located.

Awesome find dude! Thats a great price too. Im really thinking about going with these myself! Besides changing caster and moving it on a B13, what are the benifits of these? Would they be practical? I have no doubt they are total quality. Are they made of a harder Polyurethane compound than the Energy Suspensions? Im guessing the Energy Suspension Bushings keep the control arm set up in the same place, from what I see and am learning is these move the hole outward changing caster. Would these be benifitional to those of us that are lowered slighty? Any Info would awesome thanks!

SHawn B has a suspension thread that explains the benefits of the increased caster. You should take a look at it. Mike Kojima aka choaderboy2 went over the benefits of these a few years back. I'm not sure if Mikes threads are on this forum but you can definitely find them on the original sr20forum.

Sorry man I'm not 100% on all the benefits of these. I just know they improve the handling of the car. The ES bushings do not alter the location of the control arm while these shift the rear shaft of the control arm toward the wheels.

When you move the rear of the control arm to the outside of the car it will increase toe-in. The whiteline caster bushings do this. Give you moar awesome positive caster.

After installing these, you should probably get an alignment done.

Is it safe to say that if you install these and already have a perfect alignment,that all you would need is a toe adjustment?

Or is there a preferred formula for aligning after putting the whitelines on?
i.e. different toe,caster/camber settings?

Whenever I install something that would change geometry of the suspension, I would do an alignment. A replacement, not so much. i.e. worn ball joint merits a replacement control arm or a blown shock absorber, no alignment for me. But an upgrade that changes what was, yes, I would perform an alignment. Just my opinion.

Here is a direct link to the Section on bushings.

Down on the bottom is Whiteline, and a direct link to the Kojima thread and information.

As you can see, Mike K highly recommended them for anybody on the street or a track. After that, I did not bother with the details/engineering, I simply bought a set. I bought Superpro, but IIRC Superpro manufacturers them for Whiteline, or vice-versa.

Mine have been on my car since my Hyperco/AGX install, maybe 5-6 years. Still working perfectly doing whateverthehell it is that they do.

This is fantastic Information- Thanks to all! So Im assuming that by getting These Whitline caster bushings, this would not affect the installation of a Progress control arm brace, or a Whiteline 4 point underbrace right? Just wondering since its moving the control arm for caster- just wondering.

It does affect the angle of the pivot bolt. I had to use a round rasp to wittle down some of the hole on the pivot bracket and the Whiteline brace hole (the round bushing side). It's not much, but it's just enough to not allow the bolt to slide easily in there. Don't force it in there or you'll booger up the threads.

Nice! Once again- Fantastic information- thanks dude! Yeah i figured that the installation on these bushings would somewhat affect the install of either one of these braces- good info to know for all others that are planning the same install- its not exactly plug and play. Thanks again!
