I think the issue would be that you would RAISE the front of the car 5mm if you used it with stock shocks......

something thats not an issue with coilovers as you can just lower the perch.

I see, so how do you recommend those of us with stock shocks and RCE yellows to keep the Com-C's from binding up with the OEM welded flat washer? Is it possible to use WRX upper spring perches without the welded washer and then use the OEM conical washer to allow them to contact the right area of the Com-C inner bearing? That way the ride height isn't changed.

Either way, I think something needs to be in between the upper spring perch and the Com-C's. They were hitting each other over bumps when I used the Com-C's. I think that the FLAT-ness of the OEM welded washer is also not playing nicely with the angle it's attacking the Com-C bearing due to the increased negative camber added.

[ATL BRZ]

I don't want to have to buy coilovers just to use the Com-C's without destroying them or compromising the ride height given by the RCE yellows.

It's reasonable to expect the combination of parts included in the RCE suspension starter pack to all work together or at least be tested to ensure this kind of issue doesn't arise.

Adding a conical washer on top of the OEM spring perch MAY solve your issues. It will add maybe 5mm of ride height though. You can't use the older Impreza spring perch because the spring diameter is not the same.

The WL tops were tested on our car and have been working fine on many cars. The fact of the matter is, and I'm sure you'll agree, the quality control on both the bearings and the rubber of the whiteline com c mounts is very disappointing. I think the bearings you received were bad, and I think the rubber in your tops was deforming too much too. Frankly if I were you I would not feel comfortable running the WL tops anymore and we're a little disappointed ourselves. At this point I would recommend group n tops with the AVO control arm bushing, which is what we are running now. If you want to try the conical washer on the OEM perch with the com c tops, its worth a shot but if you want to get rid of them we would like to help.

FWIW, a video of the stock top hats while turning the wheel while stopped showed the exact same behavior.

Oh ok, well that makes sense. I'm going to install the washers tomorrow morning (just got them in today) and I'll see if there was any change. The mount spins freely when out of the car.

i thought i'd just continue here rather than starting a new thread regarding my issue with Com C and KW.

i had the above installed by a mechanic on Friday with the Subaru conical washers and it was fine for a few days. then after getting alignment done today, the right hand side is making knocking sound while turning. the alignment guy only undo the 2 big bolts at the bottom of the strut and didn't touch the strut top. he got me to turn the steering while putting his hand on the Com C rubber and he said he could feel the knock from it. does this mean the bearing is bad now?

thanks in advance.

Is it a loud PING sound?

no, it's just "knock" "knock" "knock" as i turn. the rubber seems to be in proper shape (ie. not like the video posted by OP).

It's your helper spring slipping on the coupler to your main spring possibly. Lube it with teflon spray.

thanks. let me try this. very much appreciated.

would lithium grease be ok to lube? i have a spare can at home.

Sorry that's actually what I meant. Use sparingly due to dust/dirt attraction. You can also try WD40 type stuff since it might actually get between the spring and plastic spacer.
