:dunno: Uh? you are right, there is a mistake here, 51770421056 is the right part for 21"s and 20"s., Cant be sure about the other part even though dealer confirmed that.

ctgilles,

Where did you buy the wheels and how much did you pay for them?

Marius Knur [mr-exclusiv*at*gmx.de]

A 22 hour round trip, €100 diesel, €12 for the BMW Museum (I just had to go since I was in Munich :D) and €3109 for the wheels. They cost €3800 including tax but I bought them on the company so without VAT.

He's a very correct person. They were balanced and fitted with 285/325 Dunlop SP Sport Maxx Runflats :thumbup:


51770421056 is correct. €83 + 21% VAT at my local dealer = CHEAP :wow: and not very BMW-like :D Funny how nobody believed it since it was so cheap LOL

I was hoping it was a US dealer, then I'd call them up to ask some details. Here is my GUESS, I think you need the 20" flares kit which is the -056 and if you have 21" wheels then you'll also need the -390 kit which will give you wider rear flares? I think. This is just my speculation based on the parts involved (see below). Please feel free to correct the info anytime.

Interesting..
What have you done with your previous wheels.

Did they buy them over or are you keeping them for in the winter

They have Continental RFT winter tyres mounted. What a difference in ride quality lol :rofl:

Retrofit kit, wheel arch extensions 21" 51710007390
 

Hello,

Has anyone ordered the Retrofit kit, wheel arch extensions 21" 51710007390?

Are the deflectors just a wider version of the little mini mudflap thingies in front of the wheel well?

Thanks.

Is there a how to installation guide for the wheel arch extension kit and what is recommended to make for an easier install?
