OP has an XI, so the reinforcement plates should already be there, right?

Absolutely.

My car didnt come with them and now my strut towers are mushroomed. Ive put them on to prevent further stressing and deformation of the towers. I would highly recommend them if you dont have them. Mushrooming is a problem with all e46's. In fact, I now have the fenders tearing away on both sides. It pisses me off that they didnt design these into the car. Structurally, its a weak point, it seems.

I dont know if the Xi has the strut plate or not from the factory. Its best to check visually. You will see them by looking at the top of the tower.

The rear plates were put on the Z3, so I dont think the Xi would have had them from the factory.

These plates cost very little and will prevent very expensive repairs if/when your tower/shock mounts mushroom or crack.

Front reinforcement plates come with the xi's...thank goodness we have our own forum. Rears do not and could be added (I bought some today).

I am late to this topic am currently going through this. I would get coilovers if I were to do this again. The OEM design of the strut is prone to spring rusting because it drains poorly. Installing coilovers will get rid of the problem. Not to mention better product in terms of weight savings, ride height and damper rate adjustments to fit your needs.

My Eibach springs cost me around $400. Koni shocks around $300 to $400. Labor now $150 X 2 = $300 because I found out about the broken springs when installing new shocks. You end up with almost the same cost and end up with a better product at the end of the day.

Coilover ride quality is a lot worse than a traditional setup, especially if your buying a low cost (same as spring/shock) coilover set.

OK, here's what I learned...coil overs offer many good things but daily driver ride and keeping the ability to install chains if necessary isn't on the list. Bilsteins are the likely best alternative to stock and offer a little stiffer ride but nothing near performance oriented (read: track days) shocks & struts.

My original symptoms were confirmed today by one of the two dealers I trust. My shocks & struts are just fine, no leaks, proper compression & rebound, springs are all good too. OBTW, dealer said that the 99 & 00 springs were either a different part number or changed possibly due to design issues. My 01 springs have not been an issue and rarely break...just his opinion and based on 25 yrs BMW service. He inspected the entire underside of the car and only found the following two issues...

First, my trailing arm bushings are shot and need replacing. This requires a four wheel alignment. Interestingly, he noticed that the rear adjustments for (I believe) toe in was set to max in one direction. He suggested that I'd likely prematurely wear out the inside tread of my new Conti tires if left alone. I could see exactly what he was talking about because he allowed me to accompany him throughout the inspection.

So instead of replacing my shocks & struts I only need the trailing arm bushings and an alignment.

Just replacing the bushings & end links will make a difference.

OP doesn't listen to advice. He was told numerous times earlier in this thread that coilovers and Bilsteins would cause a major compromise in ride quality, which was one of his parameters in post #1. It took him until the 48th post to believe it. It will be many more posts until he believes his shocks are blown.

Regardless of the stubbornness, his thread has been full of very informative information.

Dreamliner - I had a really sarcastic response but decided not to bore the others with our banter. I'll take your advice to a degree and ask the mechanic to go for a test drive with me on several different road surfaces and speeds. However, his up close and personal inspection did not reveal the need for new shocks and/or struts. But let's see what his 25+ years of BMW service can offer after a test ride.

For God sake man, the guy could have easily recommended new shocks/struts and made a bunch of money on installation (I plan to supply parts) but did not. So many Fanatics point their finger at the dealer and here is one who is doing a good job and gets blasted.

Define ride quality. H&R coilover costs $1200.

http://www.ecstuning.com/BMW-E46-325...Overs/ES10821/

I paid $700 total for Eibach springs and Bilstein HDs. Plus $600 for 2X labor because you never know if your rear springs are toast. Why wouldn't anyone looking at this spend an extra $200 at the end of the day for a much better set up? BMW aftermarket parts are so cheap compare to Porsches..

I would not call BMW ride quality as a good ride. Your definition is subjective. OP should get what he wants as deemed acceptable to him.

Evidently, OP likes the ride of blown shocks.
