The hunt for new rims A5 sportback (B8)

Hi.

I have now owned my Audi A5 Sportback 2011 2.0 tdi quattro -Proline for 6 months and i am on the move to lower it and get me some 20" rims instead of the 18" original.

This is no trackdaycar, just my daily driver so i am thinking of getting the H&R 35mm springs and a pair of RS5 rims.

I have found a pair of rims for a good price and i am just wondering how this will work out.

20" Rs rims with Mazzini 255/35/20
8.5jx20 et:25, 66.6, 5x112

Will this work or may i run into any problems with this?

Thanks
Fredrik (from Sweden so have some mercy on my grammar 🙂 )

They'll work but at 8.5J ET25 you might want to look into some spacers for a flusher fitment. Use www.willtheyfit.com for a nice calculator. Also I wonder if the rolling circumference of your choice of wheels might be off a little but the calculator will show if that's the case too.

Lycka till!

This was a package deal i found for sale "private" so therefore i had to check first.

What is the "best" possible sizing to get a proper flush fit without using spacers?
I will check the page and compare with what i have today to get the correct wheel size for the rolling circumference, i did actually not think about that... is it 3% it can be off from what is stated in the registration papers from the factory?

The sportback might differ from my coupe so you might be best off taking your wheels off and checking their specs before measuring horizontally the distance between the tire and the wheel arch and decide on a distance you would be happy with for how much further out you would like the wheel to sit.

For my coupe there is a slight offset difference from front to rear for a flush fitment, but off the top of my head I would look at a 10" wide wheel with the offset as close to ET30 as possible and you'd probably need a small spacer at the rear. Also, for a daily, the -35mm H&R springs will be extremely low (I had them on mine) and I recommend the KW HAS kit or the H&R -25mm springs on every single lowering thread asked here.

Not sure about the allowed circumference % difference from OEM, it might be 3% but of course you would like to get it as close as possible.

Regards

Perfect, i have now checked the link you sent me and looked around on some different sites etc. and i am now looking for both 19 or 20" wheel with 9,5 or 10" width and an et between 25 to 30.
I am aware of that i may need to play with a spacer if needed but that is no problem for me.

Regarding the springs i appreciate the feedback, i have seen some H&R with different specs that states -25 front and -20 rear, maybe that will be a better fit so i can use it daily?

Tack för att du svarar på mina frågor
