RTAB Replacement Essential? (I searched...)

Hi there,

First off, I searched the forums, but couldn't find a real clear-cut answer to this question. Any insight would be appreciated.

I have a 2000 323i, 115k miles, 5-speed. I've replaced most suspension parts, including adding heavy duty Meyle bushings to the front just recently.

Decided to have OE M3 RTAB installed, but my mechanic told me that he has never seen RTAB go bad on a street car and that it's really going to make a negligible difference. Is this true? Should I save my money or have the upgrade done anyway?

Thank you.

What on Earth would possess him to

1. decline work

&

2. Think that an 18 year old piece of rubber is as nice as it was from the factory?


edit: just rent a tool and diy in a couple hours. save $$$.

Yeah, that was my thinking. He's actually a great mechanic and, in fairness, I think he was just suggesting that most of the time it isn't necessary. I'll probably install them because I agree that any original rubber on a nearly 18-year old car should be replaced.

Thank you.

Right? I had a machanic refuse to change the inner and outer rear control arm bushings once. He tried convincing me that they "never" go bad. I guess some mechanics only do jobs they feel like doing? Lol

I understand saying if something just isn't bad yet but saying something just doesn't go bad seems somewhat ignorant of ask me...few things last forever

RTABs are one of the more common failure points. Upgrade with either Lemforder M3 RTABs with delrin limiters or a poly set.

Biggest lie ever. The RTAB is one of the (if not the most) crucial part for BMW handling and is the part that deteriorates fastest. See here: http://forum.e46fanatics.com/showthr...680&highlight=

yes they wear out. the rubber may look pretty decent when removed but they have deminished in their hardness. going M3 rears would be a good upgrade.

as mentioned, people with the tool (home made or rented) can do this job and is one of the more common DIYs on the E46 suspension.
