Let's hope so! I think I might go for a drive

I'm pretty sure I have those collared nuts so I guess I have more purchase than meets the eye. I'm wondering why my installers didn't mention the issue when they put everything on. [emoji849]

Yeah they increase caster and camber, here's a quick shot of my alignment with those.

I'm not at all sensitive to tramlining so I can't comment on that with these mounts. I wouldn't even know how to detect it.

Well feels pretty good so far but I getting a high frequency vibration at speed on the hwy. I'm thinking my wheel bearings are toast. I also have some cupping on my tires per the bmw tech but I'm not sure if that could cause the vibration.

Does your car dart around at all on the highway, trying to find its way into the ruts of the road?

Wheels are balanced? Have they thrown any of the weights?

Should be. I've had 2 wheels replaced now brand new OEMs and had them installed at a tire shop so they should be good to go.

I guess I could go and get everything rebalanced as that's not much money.

No and I don't think I've ever experienced that in any car. The roads but pretty bad in NC but I've never seen visible ruts except when it's only slightly wet outside.

Also for vibrations, 9/10 times it's wheel or tire related. Also check the side to side play, there is a certain spec for that on E46 and even the slightest amount of rust on the hub face can cause vibrations.

If you bought your tires at Discount Tire they give you free balancing for the life of the tires.

Yes! Biggest qualm with the E46 was the lack of Bluetooth functionality. If I get to experience what everyone else has, I will be a happy boy! https://uploads.tapatalk-cdn.com/202...a7b0f59378.jpg

Well its been a bit of a headache getting everything working properly. Didn't realize my ZHP had the iPod adapter installed, which can really mess with things so I'm still working on getting that removed with those pesky round pins. Thankfully, at the moment, I have everything working as it should thanks to Ted, who provided excellent customer service and answered all my emails and questions, many of which were due to my incompetence [emoji28]

Unfortunately, I broke my center AC vent getting it out to make space so waiting on a replacement. Gonna try and remove the glove box to get better access behind the radio in order to have it sit flush like from factory. Currently the mass of wires really prevents that.
