If anyone wanted these, you should have jumped on the 10% off they had.

What's up with them charging $700 dollars to ship these to the USA? Shipping in UK is only ~$50.

What a fucking rip.

(Sorry if this has already been discussed)

The pricing on the website isn't right. If you call shipping is a lot less. az_240 got his for $1100 shipped.

Let us know if they accommodate the e-brake 'n all the lines. I'm happy with my purchase and have been running them a while. I have the version 1, or the one where they failed to accommodate the z32 ebrake. Btw, if you're interested in sphericals bearings rather than the subpar bushings you can contact tower240sx. Otherwise those bushings should be ok to use.

To the poster that mentioned the moonface roll center adjusters, they do some good if you plan to just keep your car stock. But you can save more money just by raising your car. Just my opinion.

Hey COOL! Thanks for the info that's much more reasonable.

GripTerror · 02-08-2011, 06:04 AM

I want PBM's spindles and LCAs front and rear yo

mysharonna · 02-08-2011, 07:57 AM

I had the same question about shipping when I bought them. I just emailed them and shipping came out to ~$90.

Thanks mmdb, I'll get a hold of him and see what he can do. I was just going to run the stock bushings for a while and then switch them out later to save $ and also to see if they are really that bad for drifting. I imagine for road racing where you are holding a line through a long sweeper you would notice more of a difference.

That's the housing you will need for the high misalignment spherical bearing.

Sorry for the late response, but I'm pretty much over cars right now and have barely been on any car websites lately.

Well I happened to have an extra OEM bushing laying around so I measured it. I, unfortunately, have lost my calipers so I had to use a measuring tape. They appear to be ~29-30mm in diameter and obviously they use a 12mm bolt.

Sooooooooo......why wouldn't this work?

They should fit right in and only require some custom misalignment bushings.

singlecamslam · 02-08-2011, 07:58 PM

Doesnt Def sell a complete rear spindle bearing kit? Or it this just a cheaper alternative, i didnt see a price on the link. Looks very doable

how you plan to center them in the arms and keep them from moving?

bushing ODs need to be held to .0001" to work.

They're 22 bucks a piece, so $132 for both rear spindles. You wouldn't be able to just slap them in, but maybe something cost effective can be done.

What do you mean the OD need to be held to .0001 to work?

I figured to center it you could just use two pieces of tubing to make sure its lined up in the middle. Say the hole on the spindle is 30mm wide, the bearing housing is 12mm wide, so two 9mm pieces of tubing made flush with the outside of the spindle hole would mean the bearing was centered. Some red lock tight on those pieces of tubing would help keep the bearing from moving.

Not sure how that idea sounds, but it doesn't seem too terrible. I'm no engineer, just trying to figure out more cost effective ways for people willing to get their hands dirty. No disrespect to Def or Skull Works at all, they make an excellent product. I have their Z32 shock mount sphericals and I love them.

plus the misalignment spacers
don't know if something is available off the shelf that would work

first few bushings we made where a few thousands too high on the OD
they warped/crushed when I pressed them in onto the upright

Loctite 620 is what you what you'd want to use

95KA-Turbo · 02-09-2011, 07:03 AM

Ah I understand now. Thank you for the advice.

The misalignment spacers are the only thing I am still mulling over. My friend's dad owns a machine shop and I can get some stuff made there super cheap. I just have to draw it up in a format they can use.

articdragon192 · 02-11-2011, 01:01 AM

So, I had a few questions in track. Like, how does it affect the car? What give and take is there from widening or narrowing the track? I ask this because on my Z32 I have pushed out the rear a good amount from stock and the front is pushed out as well, but no where near as much as the rears, when compared to stock. And I'm just trying to see if I'm screwing with something too much and if evening out the change in track, front and rear, would be more ideal.

nieko · 02-11-2011, 01:12 AM

I think the only real change is your center of gravity.

But i'm sure the other bro's will come in with much more input. haha

I know the front will affect/increase your scrub radius.

Then, for both, it will increase the leverage on your suspension, effectively altering the motion ratio of your suspension slightly. Someone correct me if I'm wrong.

I don't think it's something to be too worried about in my opinion.

I'll save you some time. There's no off the shelf bearing that will fit into the Z32 upright bushing bores.

The misalignment bushings will need to be custom as you're also finding.

It's a lot of machining trying to do it the way you're thinking. I know, I bought the stuff and almost went through with it. Easier to just get stuff made to work with the stock uprights... which at that point, you might want to look into just buying a set of super sweet RUSBs and making your life easy.

PoorMans180SX · 02-17-2011, 08:25 PM

Boxed my LCA's today.

Knuckles are next. Just for fun because I'll be ordering DW knuckles in a couple months.

Anyone have any more feedback on whatever setups they have? Alignment tweaks maybe?

dont you generally want to remove the bump stop? why did you not box the arms higher up to the bushing? and what thickness you used, looks like 14 gauge to me?

PoorMans180SX · 02-18-2011, 05:58 AM

I used 1/8in plate. I don't even know what guage that is hah, but it's basically the same thickness as the control arm.

I wanted the bumpstop just for an extra safetey measure, as I'm pretty low and I don't know where the tie rod end is going to go when I modify the knuckles. I don't really think I'll miss two degrees of steering lock.

Also, I didn't want to heat up the rubber busing too much by welding close to it. If the bushing had been out, I would have welded farther up. They were new control arms and I didn't feel like pressing the bushing out to gain marginally more strength.

nieko · 02-22-2011, 07:57 PM

Soooo

ms!3 · 02-22-2011, 08:03 PM

Ive always wondered how you adjust caster from the shock? seems like it would just make the shock angle different, not actually move the wheel base -/+.

nieko · 02-22-2011, 08:40 PM

Bro... Changing the shock angle IS caster. lol

ms!3 · 02-22-2011, 09:22 PM

lolololol, i thought actually moving the wheel base was changing the caster?

im guessing wheel base is another subject. excuse my ignorance.

articdragon192 · 02-22-2011, 11:23 PM

On Macphearson strut, the angle of the shock is the caster.
On multilink or double a-arm suspension, the angle of the line through the upper and lower pivot point when compared to a line perpendicular to the floor is your caster angle. The angle of the shock does not affect caster in these two scenarios.

nieko · 02-23-2011, 12:59 AM

haha simple mistake I suppose.

You are thinking the actual pulling of the wheel forward is the caster.

Pulling the wheel forward, means the shock angle is changing.

haha

Caster, YAY
