Go w/ OEM or aftermarket struts and brakes?
So I was hit with a MASSIVE estimate, my front struts are leaking, I guess due to hitting too many severe potholes, tech recommends changing the rear shocks as well. My brake pads and rotors are at the bare minimum and need replacing also, all 4 are worn. I'm looking at over $5K including tax.
Did anyone do these jobs and have any advice (keep using OEM or recommended aftermarket brands/parts)? I'm over 200,000kms (~124,000 miles) and these are my original brakes/struts/shocks [did I get good life out of them?]. TY. |

I have only tried Koni FSD dampers, and like them over worn OEMs with stock springs. I would say that any variable frequency damper should be on your short list. But they need to be Z4 e89 N54 specific of course.
As for brakes it depends on your application. For light track use you can go far with stock rotors, performance pads and performance brake fluid assuming you get EUR rotors in Canada. |

For brake pads and rotors, I would definitely not go with OEM. There are many options out there that are cheaper and better than OEMs. Tire rack is a good place to start to check your options, there are many.
No need to get fancy with big brake kits, slotted, or drilled rotors for street applications, it'll just be for aesthetics. Get a pad that is designed to keep noise and dust minimum while working well in cold temps. If you want to keep the adaptive suspension then you'd need to get the OEM ones. Otherwise get a good aftermarket coilover like KWs, bilstein, H&R, etc. However, with an aftermarket one you'll need to do the EDC (electronic damping control) delete else you'll get an error code. All coilovers are adjustable, so you can keep it at stock height and keep the damping on the softest setting. Although it will be more firm than OEM. Just because a suspension has a higher spring rate and is more firm does not mean it is less comfortable. Stiffer + better damping > soft ride + crappy damping. But honestly if you don't want to deal with all that stuff like EDC delete, height adjustments, and manual damping adjustments, I would just get the OEMs my 2 cents, best of luck! |

Anyway, does it make sense that total cost will be around CAD5,000 (about USD3,900) to have all my suspension and brakes replaced?
I'm confused about the brakes part....Should it just be the old pads replaced...Why do I have to replace everything? |

The programming is cheaper than buying the cancellation units. Just note that you don't want to go to the dealer and get complete software updates, as that will erase the programming. So ... if you decide to go do the programming route, and you have a later model car, suggest you go to BMW and get the latest updates, then have the programming done. Filippo
