I was just about to respond saying I know about the Michelin man, he was just no where to be found.

I've been reading this thread with some interest. My 228i THP has just 6300 road miles, maybe a little enthusiastic at times, but nothing really hard, and certainly no track time. The outsides of my front PSSs are scrubbed to hell already, and no little Michelin Man visible (I can see it on the much-less-worn rears).

REAR


I ran the fronts at around 33psi (32 indicated on the iDrive) until recently when I upped them to 37 (35.5 indicated) which certainly improved both the road noise and the steering feel, but there's no accounting for lack of camber...

With just street driving you are a good candidate for the lower control arm and tension strut replacement. This is one modification that will save you considerable money over time with fewer Michelin Pilot Super Sport purchases.

I'm planning Dinan springs and bumpstops. I haven't quite talked myself into the LCAs yet.

Then sand down the spot really well to get rid of any burs and spray paint it to protect it from the elements.

I would actually feel more comfortable doing that over narrowing the perch. It should not require you to take that much material off.

Anthony and Walker you guys are such wusses. Just increase the spring diameter the manly way:

I've done that to one of my cars. It was 20 years ago...don't judge me

I'll give it a go this weekend

Well your choices are either continue to put Mr. Michelin's children through college or pay BMW for some control arms!

I though those wheels you sold me looked a little crispy on the inside.

That's what happens when you're an Army private on a very low income

Hope the wheels worked out for you

Fair point. Still trying to settle on a shop near me that I trust to do all this.

To accommodate the stock isolator properly, the nose needs to be machined 2mm smaller/thinner. I don't know if 2 out of 11 is a big deal here. The perch itself (on its load bearing surface) is a good bit thinner than 9mm though...

Some videos of the noise I experienced without the isolators installed:

Good God, that is not how a $45-60K car should sound. I could never tolerate such noise in any of my cars except for one that used for track-only duty. How some of you can tolerate that noise and the obvious issue of spring bind blows my mind. Why can't Vorshlag just machine the perch to make the isolator work? I know Vorshlag makes high quality parts, but DAMN, their egos can really get in the way of making a good product for a street car.

Since Vorshlag won't revise the perch, perhaps go to a machine shop and have them modify the perch as necessary.

Rather than machine the existing aluminum plate I would have the machine shop make a new plate with a narrower perch using 7075-T6 aluminum. That way you could make up any potential loss of strength with a stronger more corrosion resistant aluminum.

Reminiscent of Dinan and their objecting to customers' complaints of rattles, suggesting the some customers are more sensitive to the normal noises associated with camber plates. Dinan finally came around and is finalizing a solution. Hopefully Vorshlag will too.

Vorshlag has notified me they're re-designing the perch to better accommodate the stock isolator and spring. They'll be sending me a new set of plates to evaluate.

Kudos to Vorshlag for going the extra mile here: apparently, they went back and put their initial testers under an interrogation lamp , wherein the testers confessed to hearing the same things as I did.

That's great news! Glad I will have an alternative if this Dinan fix doesn't work out.

Just remember camber plates is a race car part you are using on the street so a noise here and there should be expected. If there is a flaw in the design, that obviously should be fixed.

I'd say "fair enough", but I think this is a cop-out.

The vendors for every plate I've tried have all claimed that their products make no noise (implying street-ability), but none have really delivered on this promise, instead retreating to "well, it is a race part..."

I realize now that you can't expect a spherical bearing to be noise free in this application, no matter how tight or how big.

This platform really needs a solution for the street, though. Everyone I talk to about their F-series car, whether they track it or not, complains about outer front tire wear. I suspect that a fully streetable camber plate (e.g. fixed at -1.0deg or -1.5deg with a urethane or rubber top bushing) would sell like hotcakes.

I must say mine don't make anywhere near the noise yours do in that video. Worst i get is a very slight rattle at low speed (stock perch and springs with dust boot in place). Have they improved at all over time?

installation of the stock isolators fixed the issue covered by my video

the slight rattle at low speed is what I'm griping about: you'll find that you'll be able to hear it at nearly any speed over rough surfaces, and that it will become worse over time, ultimately requiring replacement

Ah right, i see.

The only concern i have regarding the design is the less than optimal perch configuration with the isolator in place. Which could prove costly to amend even just replacing that part (when they update it) on this side of the pond. If i don't encounter any major issues with it, ill probably leave it be.

Luckily most of the roads i use are in pretty good condition, bar the odd pothole here and there. Its mainly going over speed humps where the rattle really reveals itself, but I'm finding it entirely liveable atm. Tyre roar and wind noise go some way to cancel it out at highway speeds, and its more or less imperceptible with music playing. Saying that, i wouldn't want it to get much worse than what it currently is being a dd. So as long as these prove to be durable and long life, ill be a happy camper.
