RTAB limiters

[Jembo]

.... but can I fit the limiters with out new bushing? ( oem or poly )

You can... though on a 50k car are likely to be shot.

Some prefer OEM bushes + shims (otherwise known as limiters), some just fit polybushes & some poly everything in sight

Out of interest, other than polybushing the ARB’s & main RTAB, any other of those robber joints you’d suggest getting done (with pics if possible)

Cheers

fcab's rtab's and arb bushings (front/rear) make the most difference in handling imho and are quite easily changed.
the rear upper/lower arm and subframe bushings give some more feel in the chassis, so you can feel a bit more accurate what the back end does.
But they are hard to exchange compared to those other bushings.
The rear diff bushing (on non z4m at least) is also a known failure point.

i have powerflex rear bushings no problems so far ! just use enough grease they will make noise if you not use enough grease

Are there any guides on performing the RTAB limiter install on the Z4?

I can't seem to find any.

It’s exactly the same process as the RTAB’s, they just slot into the space, even if a real squeeze with new bushes & limiters

There is a guide on here somewhere & you need a special very expensive alignment tool... here’s jantekin using his one while I helped change his RTAB’s

I don't suppose anyone has a set they can measure? Ive got a lathe so I'd like to make my own without having to take the car apart to measure up
