What are even the point of these things? I'm looking into getting a buddy club racing spec suspension since my friend is now a distributor for them, and the upper pillowball mounts are an additional 250...

this is going to be for a mostly street driven car that will see weeekend autocrosses and drag strip trips, with maybe 2-3 road course events, and will be put to sleep for the winter...

thanks

 

nope. not necessary at all.

pillow ball is just their way of saying spherical bearing. its useful for macpherson type suspension where the dampener acts as the strut which means it connects the hub directly to the chassis and angles up as the wheel moves up. in this type of suspension, that angular movement is relieved by the use of the spherical bearing. honda double wishbone suspension is specifically designed so the dampener is not the direct load bearing member of the suspension and isnt so affected by changes of camber as the wheel moves up. so its really not useful or necessary, but sure sounds impressive saying you spent the extra $250 for JDM pillowball mounts.

 

lol thanks for the explanation

i need to go buy butt padding for the 12/8 K spring rates now

 

my opinion differs as usual around here....

you want to minimize deflection , soft oem rubber shock bushings are mush , spherical bearings have zero deflection , I would say if you are running those rates PB mounts would be very beneficial.

they arent just bling , they serve a purpose and do a very nice job at that.

 

i understand, but this is my summer daily.... for the price u pay for them versus the amount of "real" events i'll be attending I don't know if they are worth the extra 250?

i can always pick them up later on right

Oem honda shock mount bushings are like gummy bears. I can grab the top of my shock and move it around, granted slighty, but this is with one hand. I got a set of ES upper shock mount bushings I'm going to put in another set of shock mounts. Type R bushings are supposed to be alot better, with a thicker metal sleeve, harder rubber, and less actual rubber.

 

if you want stiff bushings, get type R bushings. they are different. theres a pic of em in some other thread a long time ago.

12K 8K rates and a "daily" ?

have fun there Mr. overkill.

 

it should be an adventure

My street Hondas and most of the racing ones that use a pin style (normal Honda) upper mount have stock rubber upper shock mount bushings in good condition properly mounted. On a wishbone suspension car, the top pin rubbers simply locates the top of the shock rod and are not weight bearing whatsoever. I have used urathane bushings periodically but find no need to on the street and prefer the better isolation on rubber for the street. I would not even consider a "pillow ball" style mount on such a car (especially street) and think they are silly and misdirection of money that could be better spent for something that did something beneficial. My .02.

 

Thanks for jumping in, Lee. This was a topic I was hoping to cover in a phone conversation, but this will save us both some time.

For a racing-only application (autocross), it seems that one would want immediate response from the shock for low frequency, low piston-speed events like body roll. This would favor the use of higher durometer bushings, from harder rubber to urethane and all the way up to metal bearings. But those same hard bushings would remove the isolation from high frequency, high speed events. Ripples, rumbles, and small bumps. More "noise" to the shock, if you will.

So, my question is, which is more important? And does it depend on the type of shock you are using (monotube, twin, etc.).

My Koni 28's came with spherical bearings in the bottom. Is that a bad thing, a good thing or does it not matter?

I ask because I am trying to decide what to do bushing-wise on the Civic with the revalved Koni Sports.

Thanks!
