Who do we like for trac-spec FCABS these days?

[Fresh1179]

I had two sets of Powerflex fail on me before I learned my lesson and purchased the Turner Monoballs. No slop in the fitment and no noise. I’m enjoying them.

This AKG FCAB has 37 track events on it over the course of 5 years.

I wouldn't get PF or AKG. They're just not going to last.

I think the only options worth considering are, in order of harshness...
Stock (trouble free, reasonable service life, silent, soft)
Rouge engineering (trouble free, reasonable service life, not solid)
Turner monoball (best design but seems to have very hit and miss build quality-- noisy for many, but not all... and the noise is from fitment slop, not the monoball)
Bimmerword trackcabs (no experience with these, so can't comment further)

I also used a hydraulic press. Both were just fine when cold. The passenger side one only popped once the car warmed up and the exhaust heated it.

Have to be very careful when pressing these in. If it goes in the least bit crooked the bearing is going to bind and result in a popping noise.

If it’s popping then it wasn’t pressed in straight. It’s harder than you think. Really have to use a press on a stand.

I used a member by the name of TheFly to press them into OE lolipops. He did a bunch of them, I believe he used a hydraulic press.

I tried a set of these as well and had binding/popping on the one next to the exhaust once the car warmed up. Haven't tried them again since. Was this the same issue you were having?

Yup!

The design is good but the QC/QA is horrible. Went through 3 sets of these and then gave up.

There is some misconception with these being a “sealed bearing”. Usually sealed bearings do not need to be greased. But the old grease has to go somewhere, namely past the seals. Some on the old forum (myself included) were getting bent out of shape that when they greased it that is was getting passed the seals. IMO this is normal and you should grease it until grease exits around the whole bearing.

There is also a troubleshooting document that Turner published, they don’t include it when you buy it. I would ask for it before you install as these things are very sensitive to binding under load and position on the control arm.

When greasing them grease supposed to come out around the seal. I usually grease them every oil change but I change oil once every month during track season so it more often the usual. They are every sensitive to binging, got to make sure they are going straight in when installing them. I had great success with them so I can’t complain.

Yes those are it.

I have the Turner FCABs. They require maintenance and have seals. I’m assuming they labeled them as sealed bearings meaning they have seals and not that they are leak proof.

I pressed them in myself into OE housings. Haven’t had an issue with them so far. I get better feel through the steering wheel. Not sure about tire wear but so far so good.

I ran OE FCABs before and had good results.
