Ideal offset for a B5 A4

[Rhynolite]

What would be the ideal offset for an A4 so that the wheel and tire are as close to the outside of the fender as possible?

[DarkstaR]

I'm gonna take a wild guest here as I'm unfamiliar with B5s but isn't it something like +35mm? or lower?

[MikekiM]

It depends on the width of the rim.
At a 8.5" wide, an ET35 is pretty good.

[Rhynolite]

Thanks Mike, what about straight 8"? Would it still be very close to ET35?

[MikekiM]

With an 8", a ET30 would fit exactly the same as the 8.5" ET35.

thats what i rock on my b6, The cars stance looks a lot better on the wider wheels. i couldnt take the stock wheels

[PhätTony]

how bout the s4? same?

Sounds good! :tup2:

My S4 is stock +45 offset with a 7.5" wheel. I put +35mm offset with an 8" wheel (Early B7 S4/A4 S-Line/RS6 Wheels) and needed 10mm spacers in front (to clear brakes, which s4s are bigger) and somewhere around 17-25mm in the back to clear some suspension issues (I had a spare 25mm laying around so I used that).

We should also look to putting together a list of wheel offset and wheel widths that are "safe" or "recommended"

I'll start the list, and once we get some confirmation of the specs ill post it somewhere. We will also note that on the edges of the offset #, will be more likely to run.

For example, I had the BBS RS-GT 19x8.5 with ET32 and they rubbed the inside carpet just a lil, but is still considered safe to me



B5 A4/S4
8.5" - ET32-38


B6/B7 A4/S4
8.5" - ET32-38

Found out 18x8 et 47 is a no no when slammed. Scraping on the coils! :tdown:

Should be have A4 THEN S4 because I know (at least on the b5) that the front brakes on the s4 or much bigger then the a4.

[JETTAone420]

so how well would 17" fit an s4??
8.5" upfront with et of 15
and 10" in the rear with an et of 17

You mean destroy the center diff. You could get away with 1" width deviation with the right tire setup, but anything more would kill quattro.

S4 people tend not to get staggered setups.

but offset is offset
break clearance is a combination of offset and wheel design

so it is doable then?

i dont care much for making extreme use of awd lol. i jst know i want an s4 and i want some nice rims

It's not that you won't "use" awd. You will break it, literally. You can't turn awd on and off on the s4. It's on and if there is a difference in traction from the front and rear, the center diff will struggle and break eventually depending on driving conditions (either sooner or later).

There are perfectly good quattro-friendly wheels, and some that even look staggered.

By the way that it looks

EX:

B5 A4/S4
ET: ##-##
Width: #"

It makes it look like they will fit both with clearance.

My wheels fit on the front of a b5 A4 no problem, but the b5 s4 needs spacers of u front.

My 0.02$

but see, the original post is referring to offset

the issue with your wheels is not necessarily offset, its the design of the wheel
you could find another wheel with the exact width and offset, but clears the S4 brakes

so, should specify if your trying to see which "wheels" fit versus which "offset" fits

You are a clever man.

im 19x8.5 +35 all around.

I have never heard this, and it really doesn't make much sense. Staggered widths are fine for quattro, you have a difference in traction front/rear every time you accelerate or turn or slow down. You just can't run staggered heights because the smaller end would ALWAYS be turning faster than the bigger end, which would burn up the torsein center diff. :tup:

I run 17x8 et35 w/ 225/45-17 tires, it sits pretty flush. I'll get some pictures when my car is back on the ground.

Staggered LOOKS badass, but it's true that it's horrible for the awd. When turning, diameters wouldn't matter because the diffs would open up so the wheels turn at different speeds anyway, but driving on the freeway, every wheel is trying to turn at the same speed. If the diameters of the tires are off by more than 2-3%, you can severely damage your differentials.

It's not the front and rear diffs that it affects though, it's the center diff.


I'm not sure if you're agreeing or disagreeing with me? :D

[89_16v_gti]

Its the diameter of the tires not the width. You could run a 245/60-17 in the front and a 295/50-17 in the rear and never have a problem. the diameter of those tires are the same. If you had tires with a different hight front and back that would cause the driveshafts to spin at two different speeds and you would burn up the center diff.

There we go. :)

this is the stance im gonna be going for...
