ADV1 Wheels 20" front and 21" back is that OK?

[ThorstenAlbers]

Hi Guys,

i got my ADV1 Wheels delivered today and the dealer gave me the advise to NOT RUN them in that combination.
Of course they maybe carefull to say that is OK, but i am afraid that the differential may brake?

Does anybody have a technical understanding?

The wheel specialist told me, that there are a lot of huracans out with that wheel combination, he is such convinced that nithing happens.

We have members that have this combo for over an year now, no problems so far. Install them and post up some pics

We've never had a customer come in with a Huracan that DID NOT opt for the 20//21 setup. As long as you run the correct tire setup you will be good. Dealers are always going to lose their minds when you buy anything that's outside of the dealer haha

Dealer has a valid concern without knowing the full details of what the wheel ratios will be after new tires are introduced. With AWD cars you need to mind the rolling ratios between front and rear as you could throw off the viscous coupling (google that if you want to learn more , in the 580 you do not need to worry, you didn't mention which car. That said tons of people have been running the 20/21 fitment without issue, apparently the ratios are close enough.

Having personally had experience with different wheel weighted Gallardos, I knew the last thing I wanted was more weight, so I stuck with the 20" OEM sizing, which also allowed me to use my OEM tires and sensors, a good 2k + savings. And frankly, I think the meaty 20" rear looks just fine on the H, especially if you have pot hole filled roads like we do in Chicago. One last think Ill mention on the 20's if ordering new, be sure you get the Lambo specific 20's, TireRack has both a true OEM and a like OEM sized tire...they are very different, costs are about same. The true OEM tire will have the Lambo "L" script on the sidewall.

My car on 20's all around....

I have 20/21 setup and love it.
