A lot is asked of the BMW bushing system. that is why they wear quickly.
Actually with my AST 4100's you can get a pretty decent ride out of the STi. I honestly wouldn't say my sport suspension 3 series has ever been that comfortable, even before the struts blew out of it. I'd say its spongy\washy and always has been.

cars are built to a price point. that AST suspension costs more than many used E46s.

also you can't compare a beat used e46 suspension to a new factory fresh BMW e46 suspension. that's the whole point of this: its a high wear item and needs periodic replacement.

i am sorry your e46 handled poorly.

mine does not

Congrats hopefully we can get back on topic and figure out why ours do not.

I put in the guibo and swapped the front and rear tires since they were different brands. I didn't see much of a difference in the steering tightness since mine was already tight but it runs pretty straight now with very little wander. I'm thinking it was the tires in my case. I should have driven it more after the guibo install before swapping tires just to see which fix worked. Maybe I'll try swapping the tires back to see if it gets worse. At any rate I'm MUCH happier that the car stays in its own lane!!

My tramlining was fixed by a few things: new tires, proper alignment at BMW and a new steering guibo. Even when I swapped out my entire suspension for new parts it still tramlined quite bad. My RTAB are original and will be replaced this fall. I also didn't notice a difference in my steering feel with the guibo.

Too true

And noisy when the grooves start to wear.

Changing RTABs makes a massive difference. What you might think is front end instability could actually be your RTABs pushing your car around, requiring steering adjustment to keep it straight.

See Mango's links for suspension refresh info. I've done the majority of the work and it makes a massive difference regardless of how good you think your set up is prior to the refresh
