Good/Bad news...

There are other considerations to go along with the upgrade. Fearing I may be attacked by resident experts (seems popular in this thread), I'll lightly touch on a couple things.

Lowering and adding stiffness affects other components - applied physics. Researching will outline additional recommended parts you may want to add. Basically, new rear shock mounts including reinforcing rings are often used. On the front strut towers some beef them up using aftermarket stiffening products as well. These aren't expensive and have nothing to do with performance more preventing existing parts from failing from additional forces that will be applied. Mushrooming strut towers or tearing rear shock mount body metal. Don't forget camber adjustments and a proper 4-wheel alignment should be on the list.

A good rule is everyone here wants to help and posts things they feel are useful. Few are experts and base their opinions on their personal experience or just what they've read from other non-experts. Ride comments or best results are subjective to that particular poster and not necessarily right for you. Question everything and when in doubt, continue researching. True BMW parts suppliers will clearly show different part numbers for XI's vs. I's when looking up OEM goodies that may differ. That would be your first clue something is different with the part in question. Some guys are too busy insulting each other and not supporting their all knowing comments to demonstrate much value here. That is unfortunate.

Very well put, every time post a topic on this forum either i'm being screamed at or someone else is. It's not my intention to cause any havoc on here...just looking for advice and inputs

Only reason people are "screaming" in this thread is because you were provided the wrong information to go and purchase $1k in wrong parts that won't fit your car. I apologize if that comes off as attacking but just trying to get the right information to you so that you can make an educated and knowledgable decision on which parts to buy.

WK, well said.
