I found a set of 19" Audi A7 wheels for a good price locally, wondering what you guys would think of them on my 2012 IS350, or my brothers 2014 GS350? I would probably coat them gunmetal. I like a very clean OEM look, and don't want anything that will look too big.

Thoughts?

 

seller says they're 19's but they may actually be 20's after looking them up.

 

you're in the wrong section, and aren't the Audi wheels a different bolt pattern so I don't think you'll be able to mount them unless you have adapters.

 

Sorry, but yes they are 5x112. So an adapter will be needed.

 

I was actually debating if fitting Audi or Mercedes wheels is possible and...yes it is very much so. You will need hub rings from 66.5 mm to 60.1 mm to correct the hub size and the set of wobble bolts or in case of Lexus wobble nuts also called PCD variation lugnuts.
It's not a new idea at all, been around for years,

The bolt pattern measurement is from the center of the #1 bolt to the center of the #3, #2 to #4, #3 to #5 etc. So instead of 114.3mm it's 112, divide that by two since two lugs are sharing the distance of the 2mm and you only need a little more than 1mm for each side so it's not that far off and a very reasonable solution.
Hub centric rings have no bearing on the effectiveness or safety of these specific bolts. They are very important for centering the wheel to the hub so the wheel is aligned and there is an even distribution of pressure to each lug. If it is off center because you are missing a ring you will feel a slight vibration and the uneven distribution of stress to the lugs could potentially snap a lug, loosen the lug or damage the lug seat. But the function of the ring is 99% fulfilled when the wheel is properly torqued to the hub.
The other important thing to keep in mind is that you need to have the correct seat for you rim. (ball seat, conical seat) and the the rims you are planning to put on have holes big enough to accommodate the lugs.
I have yet to read anything negative or bad happening because of them. Russ @ Raderworks knows his stuff and there is a ton of VW Audi folks running them.

If the wheels you plan to install have high offset around 50 and up you could go with wheel adapters.

Thank you for the response! Very informative and helpful!

 

Wanted to add that some Audi models have smaller center bore diameter of 57.1mm, if you want to use those the center bore needs to be bored out 3mm to fit Lexus hub.
