Has anyone tried out the PCI bronze bushing kit? Is it better than sphericals?

Here is link. You have to scroll about half way down for a pic.

I personally had the first prototype set installed on my car. They are amazing. I instantly felt the difference in steering input and response. These are definitely a great buy and very easy to rebuild if ever damaged or worn out, unlike sphericals where it would cost a whole lot more.

Feel free to PM me if you are interested in a set.

Talked to Jeff and ordered a set last night. Thanks.

Great!

can you explain how they are designed? theyre not like sphericals they say, but are they similar to OEM? or poly? pics dont show much detail.

So they're metal on metal. I mean metal on bronze. Kinda like bronze valveguides. They must press in i guess, and it seems like wear would be an issue.

Yes, the bushings are pressed into each other. Rebuild kits cost $25 bucks and can be done easily with a press. Im currently on the prototype set still, which was installed about 9-10 months ago. No problems at all, no play. I track my car monthly and still daily drive it.

in for info

so its just a straight up uniaxial metal bushing?

no compliance like rubber, no articulation like spherical?

hmm... methinks wear could be a definite issue, especially on something like the front LCA bushings. The shape of the LCA is supposed to resist fore-aft wheel movement (like during wheel hop), which I'm sure this type of bushing would greatly reduce. But do it enough, and you could end up with tons of play in the bushing, whereas a rubber bushing would continue to deflect and then return to normal shape.

And still daily drive it? Wow.

Ever tried delrin bushings? I've never actually seen a car shod with bronze bushings, but I have seen autocross cars using delrin, and the drivers reported NVH equivalent to or greater than sphericals. Since neither bronze nor delrin allow compliance of the bushing itself, I imagine the ride quality to be similar.

Hi, this is brian with PCI. Yes that is correct. Only on the front can these type of bushings be used. Over the past several years I've tested many types of bearings/bushings. Sphericals are great, but for this application if maintanence is ever required its going to be expensive and difficult to replace. Delrin or any other simaliar bushings are just not strong enough for this application. Ive made several sets and they dont last very long. I believe the bronze bearing is the way to go whenever it can be used.

This kit is has a black zinc plated cnc steel sleeve that presses into the arm. the bronze bearings then easily press into the sleeve, the bronze bearings can be removed and installed from the sleeve without a press, just a flat head screwdriver and a rubber hammer is all you will need to replace bushings. Though you shouldnt ever need to replace them, they're very strong! and if you do i will sell them very cheap.

The bushings can be pressed in offset to increase castor, up to 3.5 deg with the hard race upper arms, and 2 deg with stock.

Good for road or drag racing. For drag racing this will have the same if not better effect than tracion bars.

Interesting, sorry if this is off topic but would be giving it positive or negative castor for the reduced wheel hop and if so by how many degrees?

This is not a bad option, glad i found this thread

I'd like more info on this please.

I'm running swapped UCAs with adjustable caster (castor is a bean/oil) for 4*, but I don't see how an offset UCA bushing could change caster without suspension binding.

I don't think think the UCA has binding issues. If you offset the bushing, the UCA can be moved forwards or backwards.

Ditto. Beat me to the reply.

Which would put the LCA's lower shock mount out of alignment with the upper shock mount, which could make that bushing bind.

upper ball joint

eg6vtec1

Trust me theres no binding. the lca will move forward a 1/4" which changes the angle of the shock less than a degree, you got nothing to worry about.

You can get positive or neg but why would you want negitive?

PatrickGSR94

Ball joints have nothing to do with the angle of the shock with respect to horizontal (the bolt that goes through the bushing/shock fork should be nearly horizontal).

If you can get 2 degrees caster on the knuckle by moving the LCA forward, the shock is going to be close to that same angle. The knuckle has upper and lower ball joints, but the shock mounts to the LCA with that rigid bushing. That's why I'm saying that binding could be an issue.

Moving the upper ball joint backwards to achieve positive caster doesn't really affect anything else. But with so many things attached to the lower control arm, moving the lower ball joint forwards almost always raises the possibility of binding.

eg6vtec1

Well I can assure you there is no binding. I have bolted everything up shock installed without the spring and cycled the suspension freely with no binding. You think i would make something that binds? how dumb do you think I am? LOL

beanbag

never mind, I thought we were still talking about the uca

blinx9900

did you just quote yourself and then make it look like you cleared some confusion up for yourself?

PatrickGSR94

Well that's cool, I'm just saying the possibility is there.

brian, weren't we talking about using a spherical in the place of the bushing the fork goes through?
