Whiteline Com-c top mounts

If that's the case, I bet it could be fixed by just adding a thin smaller diameter washer to the assembly so that the load is carried by the inner race of the bearing only.

I'm curious as to why they would design the spring perch like this in the first place, especially when the impreza perch already existed with a better (IMO) design. If they wanted to do away with a separate washer, just make the attached washer conical.

I was having binding issues when I did my install back before the washer issue was well know. I used some washers from a hardware store which alleviated the binding issue but still gave me popping. It could have still been applying pressure to the outside of the bearing, but I'm not wasting another Saturday experimenting until there's a known solution. I have a pair of Impreza conical washers waiting to do it right when the Top Hats are shown to work correctly.

Just got another email back, after I tried to order...

Good to see they're trying to fix the issue, and doing the testing before rushing back onto the market.





Hi Mike,


At this stage the tops are still getting the development of the washers and are in a few cars being tested before we sell them again.

We will hopefully have them back on the shelf in about 6-8 weeks time.

Camber bolts are below.

KCA416
Front Camber adjusting bolt kit - 16mm
The biggest adjustment range up to +/- 1.75 deg. Unlike other “friction” lock designs we use a positive toothed lock washer which mean NO SLIP. Simple to adjust & lock time after time with out sli... <read more>
Adds +/- 1.5º camber
AUD $ 94.95 inc tax

Hmm I wonder how thick there washer will be. The current impreza washer is to thick for use with the konis and it raises the car. I have pics of the 3rd set I just took off the car the bearing casing has lots of wear marks on it. I also noticed the bearing casing on the oem top hat is made of thick rubber not metal. So maybe the rubber seal has some flex in it that the metal casing does not. In the pic below you can see the bottom of the top hat I just took off. you can see the wear on the bearing casing it self showing that the conical washer of the oem top hat below is digging into it. not good. below that is the stock wrx conical washer you can clearly see that the flat spot is only the size of the inner part of the bearing where the oem is much larger and does not taper.

Funny, I was just thinking that. I wonder how long it'll be before the OEM part design gets changed, or if it will. If this is effecting the whiteline parts with the same bearing other then the seal, it's sure to have some effect on the OEM parts.
@Racecomp Engineering Andy or Myles, if you have the parts handy, could you take a look and give an educated guess about the machine-ability of the built in washer? Do you know of any reason why the older two piece design wouldn't work, ie. is it taller? Thanks

I must have quoted you mid edit.

It looks like there's two spot welds holding that flat washer to the OEM perch. Do you think those could be drilled out and the washer removed. Allowing us to just get the conical washers?

I'm sure whiteline is going to do there best to give us a proper fix for this, just trying to explore options.

I'm thinking of same thing but wait until Whiteline give their result.

I ordered a new set of upper spring perches today to test out on. Should be here Friday. So we will know soon.

As I saw the pictures in this link http://forums.nasioc.com/forums/show....php?t=1757339, the method to remove welded flat washer and add a conical washer could work.

This is exactly the reason I just bought new spring perches so I can try and remove that extra welded on washer.

This is something I was thinking of trying, or machining my own washer.

I have access to a lathe, I could just leave the washers in place and machine them. I'd just create a taper at the top and simulate the conical washer. Can you, or anyone for that matter confirm that the top hats are concentric? The pic of the FRS/BRZ top hat looks like it is, but the older design clearly isn't. And I just don't remember mine sufficiently to make a decision. I have a set of the older style com-c's here that weresent to me accidentally, I might try them if this could work.

Also, I know I'm getting way off topic here, but I remember reading somewhere about the effects of having the spring offset from the strut, but I can't remember what it was. Anyone remember?

Does the old ccoms have a rubber bearing seal like the oem top hats or a metal casing like the new ones?

They do, but guys were going through them almost as often as the new style so I don't think that will be enough protect the bearing without ensuring the load goes where it's supposed to.

So everyone using coilovers with the conical washer isn't have any issues? Is that correct?
