Nope. I just saw the title and shared my experience.

dummy.

As far as the noise, I had contacted AKG when I had the first set. The customer service was great and they had informed me to clean and lube them again. Then after a certain period of time, the noise came back and they sent out another set of the fcab. I installed those based on their advice and lubed them with the supplied lube. The issue returned shortly so I ditched them and went with the Z4M fcab.

The issue from what I could tell was the inserts that go into the outer portion of the bushing and slide on the end of the control arm have excessive play and this resulted in the bushing having movement forward and back.

here's the funny part - i bought those bushings from you, remember? i have had them installed on my sedan for about 18 months now, with zero issues. maybe you've got weird control arms?

LOL.

Well glad to hear you don't have any noise or issues with them. Maybe the end of the control arms is different. I never did measure the thickness of the aluminium.

Oh my, yes. Check your giubo and CSB coupled with diff and subframe mounts - It really is smooth as glass.

Ok great! What's CSB?

must be the beefier Canadian ZAM Arms..

Carrier Support Bearing. the one in the middle of the driveshaft.

I've had the AKG 95A FCABs installed a few months ago. I haven't heard anything yet. Was it noticeable with the windows closed?

Just got back from getting the front ball joints and tie rods checked. All good, but front brake lines are not in the best shape, so going to replace those right away. ATE the way to go from what I hear?

While up on the lift I did notice there was a rectangular hole (maybe 1" x 3" or so) in what looked like a flywheel casing. Looks like some kind of cover should be on there but I can't find the part anywhere.

Does anyone know what that is called exactly or have a part number for me?

The hole is for the factory brake cooling ducts.

You might consider stainless steel brake lines as a replacement. I got my set from Turner Motorsport, they were StopTech branded.

Slater jump in and correct me if I'm wrong, but I think the ATE are already stainless (just not showing it). They run like $50 for the pair up front, which is all that was cracking on my car (rears were in good shape).

Although I did find these at ECS for $60 for the pair, but I would lose the lifetime warranty you get from FCPEuro.


But if you all think I should do all 4 corners, ECS also has this kit for the whole car for $100 compared to $125 for the stoptech kit

Should I be changing/flushing the brake fluid at this point as well?
