Are there any front camber plates that are guaranteed to be quiet?
 

My last car I installed Ground Control camber plates, and after a while I got clucking noises.

I want to add front camber, but I really REALLY want to keep the solid, noise-free ride I have now with the stock top hats.

Not worried about NVH, just don't want any clunking or knocking over bumps.

I'm running Enkei Raijins 18x8.5 45 offset, and I'm looking for 3-4 degrees front camber.

I'll use camber/crash bolts if I can get to my goal.

You should start with crash bolts and see if that does get you what you're looking for. Plus it's a cheaper route to start with. I had a ground control setup in my WRX, it only clunked if I bottomed out. That was all in the struts/springs though.

By the way NVH stands for noise, vibration, and harshness it seems you are worried about noise since you are asking for a quiet ride.

I got the HVT camber plates. So far at 8000 miles of driving and about 15 autocrosses - completely noise free operation.

You won't get anywhere near -3* with just one set of bolts. Bolts in the top hole will get you about -1.5*. I'm at -2* with offset bolts in the top hole and slight slotting of the strut.

Another concern might be clearance between the tire and spring perch. Are you running coilovers, or stock diameter springs? I have 17x8 +45's and almost zero clearance now with -2*.

Our RaceSeng CasCam plates make no noise.

I've had mine on a couple months now. I was expecting noise and a significantly shittier ride, I've been pleasantly surprised.

Have had my Raceseng CasCam setup on V3 for almost a year. No noise.

I second the raceseng plates. Have them on with the RCE T2s, and Enkei Raijins 18 x 8 +45. Currently at -3 front camber with adjustment left on the plates but I did use the slots on the T2s.

Raceseng CasCam here and only get noise at full lock, which I suspect is actually coil bind.

My Ohlins top mount is noise-free, I suspect my uninstalled Raceseng CasCam will be the same.

Clunking/knocking is a sign of a loose nut or bad bearing, something that is either from poor design or poor install. Even the best camber plates will clunk if they aren't installed right. My Ohlins did that when I first put them on, it wasn't on tight and clunked out of the driveway.
