Need help with wheel offset for 2014 audi a6 c7 quattro 3.0

[rgorajia]

Guys,

I need some desperate help!

I purchased a pair of wheels (20x9 et35 to put on the stock OEM tires (255/35/20)).

Unfortunately, the offset doesn't clear the front calipers, which is odd because I know some people are running the same tire.

The tire shop said "on paper" the wheels should fit, however, due to the wheel design, the wheel doesn't fit

HEre is the wheel:

Also - we tried to make the fronts wheels fit with a 10mm spacer, however, that kicked out the wheel too much and it obviously stuck out way past the fender.

Any suggestoins/help would be much appreciated!!!!!

I'm assuming I'll have to go down on the front offset, maybe +30 or +25?

Any way I can figure this out to make sure I don't have go through these hurdles all over again?

just because the wheel is the same offset and size does not mean it will fit, it depends on the wheel design also, the spokes are probably too concave to fit the big brakes on the a6.

as far as the offset goes, running a +25 would be the same as you running a 10mm spacer, +30 would be the same as running a 5mm spacer and so on.

if you can try to get a 3mm spacer and see if the front clears, it's a bit of trial and error at this point.

if you're dead set on getting the wheels to fit you will probably need spacers then a bit of negative camber to get the wheels to fit flush with the fenders. but if that's too much work you're better off selling the wheels and buying a set from another manufacturer that will fit for sure i.e. VMR, Hartmann or AG wheels.

hope this helps.

The "tire" you are running has nothing to do with clearing the calipers or your wheel offset.

Also, you already know that +25 wont fit ie: you said you tried a 10mm spacer - the wheels are ET 35 - so you effectively already tried ET 25 and that didn't work, in that case neither will ET 30.

As stated above the problem is the wheel design you chose. Looking at the inside it has a stepped lip, which decreases the inside barrel size of the wheel, I'd say that's why it fits on paper but not in the real world. I'm assuming you can't get the wheel over the caliper?

10mm spacer did not work because it was too far out, not because it did not clear caliper. So, 5mm spacer might work if the wheel will clear caliper. I have 9.5 wheels ET35 and they are not too far out they are just right and that is 6.35 mm more than 9xET35. (like 9x28.65) Of course if his lips are real thick it might make it different. I think wheel width is measured from bead to bead? Thick lips could make the same width wheel protrude more.

The tire does matter as far as fender clearance is concerned. more stretch gives more fender clearance which would enable the use of more aggressive offset (lower number), wider tire less (higher offset number)

255 on 9 inch has no stretch, it is middle of the range for 9 inch wheel and should be almost the same on top as the 265 I am using on the 9.5. I have 1.35mm inward at edge of tread. The 10mm spacers might (probably will) work with 245 tire

So how did the story end? What was your final configuration?
