Monoball thrust bearings and rear trailing arm bearings worth it?

Wyatt is right. It does not make it heavier. It feels more go kart like? You get immediate, positive feedback through the steering wheel on every turn. And yes, more confidence under heavy braking.

It is not really an expensive upgrade, so I think the downside is limited. I cannot imagine a scenario (unless you want to go off roading in an M3) where you’d want to take them off after installing. So give them a shot and see if it solves it for you.

after installing my GAS monoballs and new arms, which was SUPER easy to do, I'll say that if your factory thrust arm bushings are in good condition, you will notice next to ZERO difference in steering feel by switching to monoballs in most driving situations (except for maybe some places on a race track). There is simply not enough load to notice a difference in normal street driving. It's like saying you can feel a 3hp gain on a 400hp car. Your brain wants to believe it can feel something, but it really cant.

I'll have to see how the monoballs feel at 100% braking power with track pads at 150mph, which is the reason I wanted them.

When I changed to GAS monoballs my tension arm was only 10-20k kms old. Relatively new still. I did feel the difference in turn-in response, steering feel (slight), and less nose dive under braking (big).

I thought they were in back order…
