i need help with e70 rims please...

[ilir 206]

i have a 2008 e70 3.0 and it comes with the stock 18" runflats 5 stars..... i wanted to upgrade to the 21" 128 wheels however on the bmw catalogue it states that there only in combination with the self leveling suspension.... whats that about? i dont think i have the self leveling suspension ..... i guess that means i cannot install them?? any advice? knowledge? thank you.

self levelling suspension not required. 21 should be fine with the stock suspension. in australia there is no such requirement. hope this helps

Thanks for the response even my local bmw dealserships didnt give me a straight answer some said i had to get bigger control arms or i wouldnt be able to get a proper wheel alignment im looking for some feedback from others before i make the change from 18 to 21. Once again thanks for the input.
