Ordered a set about a week ago, I'll try post some pics when they are installed

I have a 2005 bmw 525i in silver...looking at making a similar look to your car accept with a carbon vinyl roof and M5 front....

Do you have any more pics by any chance, your car looks clean

 

Go with KW. I have had them on my last two vehicles and I love them.

 

im on bc coilovers, very comfortable even at that height =D, and yes im in australia

 

Wow loving your ride! May I ask what front you have on? Is it m5 + hamman lip?
Also how many inches have you lowered it? What size rims + tire profile aswell?! Perfect man!

 

Heres my M5 and I wouldnt go any lower.

 

Yea your fitments perfect! Perfect stance! I love the concave rims too...Wish I could get them for a decent price here in Aus

Are they 20'? Do you mind telling me your fitment?

thanks for the pic man its sexy!

 

The wheels are 21" ADV1 deep concave with aggressive offsets, 21x9 fronts and 21x11 rears. I have Michelin Pilot super sports and they run a tad wider than cheaper tires but grip very well. Thanks for the compliment. There are some cheaper concave designs but then weight of the wheel and durability might be compremised.

GL on your search.

 

That looks sick! Perfect ride height. Any rubbing? Did you have to roll the fenders?

 

 

+ 1 For BC's. I have them on my e46 Touring and e60.
