Need advice on brake parts replacement for my E60

[AamirAtl]

Hi, I have a 2007 550i and the front rotors have visible grooves. When stopping you can feel extreme vibration. Car stops fine though. Though iDrive says I have over 10K miles remaining on both front and rear pads, I'm thinking of changing them so I don't have to deal with the annoying vibration each time I hit the brake pedal.

Would like to know a few things:

- Should I replace both front and rear pads at the same time?
- Resurfacing/turning the front rotors is not an option so I will have to replace them. So again, should I only replace fronts or both front and rears?
- OEM pad prices for me are $110 front pair, $129 rear pair
- OEM rotor prices are $296 front pair, $344 rear pair (expensive for me)
- Sensors are $22 each times 2
- Can I use existing sensors or need new?
- Should I buy the above from the dealer or buy OEM from another source or buy aftermarket?
- If aftermarket, can you advise what brand and where? (Links would be great).

Car has 147k, got oil leaks fixed recently, would like to keep it for a while, is my DD.

Thanks for your help.

I always buy all of my brake parts for my E30 or E60 from Pelican Parts or ECS tuning. I just did full rear brakes on my E60 using parts from ECS Tuning. OEM brake parts are highway robbery and totally unncessary in my opinion.
