Which monoball RTAB to go with?

[Grke46m3]

I went with turners because they where on sale. They use a oem lemforder Benz ball joint. Went in nice as easy and you can tell it’s snug. But you can’t go wrong with any of the companies that use a oem balljoint.

Just got SDWs on Obioban's recommendation. Hooping to install and align car next week.

ethan They have switched - I confirmed with John and then I put the BW's in over the winter and have driven ~1,000 miles with them. No clunking. Press-fit of the aluminum carriers is tight! I need something substantial to press them into the trailing arm. I haven't even thought about them since installing, which is a good thing.

👍 Good news.

I put Bimmerworld units in my track car. They clunked immediately. Then I found Obioban's thread on m3forum.net in which he investigated the Indian-made balljoints used. Sure enough, when I pressed the BJs out, the races were jammed from the factory. I replaced them with Lemforder balljoints and all was well. The housings themselves are pretty nice pieces.

I don't know if Bimmerworld has switched to a new balljoint yet, and I like their products generally, but steer clear unless you can confirm.

Syncro Design Works on my car. I did not notice any increased NVH but I did notice the huge improvement in how planted the rear end feels. Great customer service too.

I have Fall Line Motorsport ones in my car.
I haven't driven it enough yet to give any impressions but they look nicely made.

Monoballs basically are ball joints instead of bushings, right?

Correct.

Went with the Synchro Design Work monoballs because they are sealed units as well. The NVH has not changed much but the rear end really tightened up.

Very pleased with my SDW's.

Syncro Design Works are really nice

A differentiation between the bearing designs is one piece vs two piece housing.

Turner's is one piece and they claim on their website (no idea if this is true) that this leads to longer life of the ball joint inside.

SDW, BimmerWorld, Ground Control, etc. are all two piece.
