YUANTUO Convertible Roof Top C Column Repair Kit Fits for BMW E46 323ci M3 330ci 325ci 2000-2006 Replace 54317135351

After installing I noticed it was much tighter/didn't fit the same way as the other side and it seemed like it would brake if I fully raised the top. I made sure I had installed it correctly and matched the other side and eventually noticed the string is not as long as oem. At first I thought the spring just needed to stretch but after comparing the one I removed to this one I realized it was about an inch too short.I ended up using one of the old brackets and a zip tie to extend where the spring attaches which actually worked very well since I could tighten the zip tie to the right length/tension.The other problem was the top string where a screw goes through the loop at the end of the string. On the side I needed to replace the loop was too small to get the screw through but the other side which I didn't need seemed fine. I was able to get another zip tie through there instead.With the use of zip ties and some headliner adhesive the top looks great now, but properly sized string would have saved a lot of headache. I'd try a different brand.

Overall fit is great however due to the crimps installed at factory I elected to discard crimps and utilize existing cabling as it made the install much simpler. My cables were in fine condition it was the plastic flaps that had busted.

So for the part, this worked great. But my issue is the tape that sticks it to the material is way to weak. I ended up having to uninstall the whole thing and put heavier tape just to get it to stick. Wished I wouldve known this the first time. Or the mfgr should put better tape on it.

A little thinner plastic than the original, but not bad. There are no instructions, so make sure you remember or diagram how the strings attach. Strings seem a little tight at first, or maybe the spring just needs to stretch a little bit. All in all, I'm satisfied. 1/3 of the price of the OEM.

Have to play with opening/closing top in order to access that small screw with spring tensioner, but size is correct. Used 3M double sided heavy duty tape, did not trust the one installed.
